Open Caveats
CSCtz86641
Symptom: WebEx UI does not allow admin to apply changes.
Condition: After uploading TPGW certificate, click Upload button. The Apply button is dimmed, so changes cannot be applied.
Workaround: Click Apply without clicking Upload. The changes are saved.
CSCtz86945
Symptom: CTMS Call-in Number endpoints cannot extend the meeting. Only One Button to Push endpoints can extend the meeting.
Condition: A scheduled meeting with WebEx is started. Call-in Number endpoints then join the meeting.
Workaround: None.
CSCtz87144
Symptom: In the Media Control dialog box, after clicking Reset All Rooms to Default, video does not switch in.
Condition: After manipulating a meeting with both triple-screen and single-screen endpoints through the Director Control interface, the administrator clicks the Reset All Rooms to Default button. After reset, the single-screen endpoints do not see active video from the triple.
Workaround: In Media Control dialog box, after clicking Reset All Rooms to Default, click and unclick any transmit or receive icon and click Apply. Normal video switching should resume.
CSCtz87376
Symptom: After video is downgraded for a meeting, endpoints that join the meeting late are not downgraded.
Condition: Video has been downgraded for the whole meeting because one endpoint received downgraded video.
Workaround: None.
CSCtz86593
Symptom: Enabling CTMS browser security does not work after upgrade
Condition: If browser security was installed and then disabled before upgrading, browser security cannot be enabled after upgrade to CTMS 1.8.3.
Workaround: Enable browser security on current CTMS release before upgrading to CTMS 1.8.3.
CSCtz76468
Symptom: Call-in Number voice prompts are not played when a TC5 (version 5.0) endpoint that is registered to VCS dials in.
Condition: The TC5 endpoint is registered to VCS. There is a trunk from VCS to CUCM.
Workaround: With VCS 7.1X, the voice prompts do not play completely. If the user still enters the meeting number, the endpoint is added to the meeting.

Condition: The meeting is secure and the participant is receiving audio from a triple-screen endpoint.
Workaround: Upgrade CTMS to software release 1.8.4.
New and Changed Information for CTMS Release 1.8.1
Alert Management
When disk usage is close to or exceeds a user-configurable threshold, an alert email is sent. The disk threshold, and email addresses for recipient and sender are configured on the Configure > Alert Management page.
CTMS sends alert emails under the following circumstances:
•
•
•
CTMS resends the alert email every 24 hours as long as the condition remains the same. If the condition changes to one of the other circumstances that triggers an alert, the new alert email is sent within an hour of the change.
Note
Email Server
On the Configure > Email Server page, an email server can be configured. CTMS uses this email server to send out the alert emails described in the Alert Management section.
New Process for Printing SDP Keys
SDP keys are not printed in logs for security reasons. Contact the Cisco Technical Assistance Center (TAC) if you need to print them.
Other Notes
When configuring VMware on the UCS server, the same OVF template used with CTMS release 1.8 can be used with release 1.8.1.

Workaround: Click Go Back and the resources are changed correctly.
CSCtx06115
Symptom: Endpoints that support 1080p resolution are dropped from the meeting.
Condition: Set Allow Downspeed setting to No on the Manage > Default Meeting Settings page and start an active static meeting.
Workaround: None.
Further Problem Description: This issue occurs with schedule and ad hoc meetings also.
New and Changed Information for CTMS Release 1.8
Supported Endpoint Types
In CTMS release 1.8, Supported Endpoint Types in the Manage > Default Meeting Settings page is introduced. With Supported Endpoint Types, you can control the endpoint types that are supported in Cisco TelePresence multipoint and network multipoint meetings managed by a particular CTMS. By default, only these endpoints are supported:
•
For information about the latest maintenance releases, see the Cisco TelePresence System Software Compatibility Matrix, which you can access at this location:
http://www.cisco.com/en/US/products/ps8332/products_device_support_tables_list.html
Optionally, you can select "Cisco TelePresence TC 5.0 (and later) and CTS 1.8 (and later) endpoints," which supports the following endpoints:
•
•
Note
While interoperating with Cisco TelePresence TC 5.0 (and later) endpoints in multipoint and network multipoint meetings, all supported endpoint types have full audio and video capabilities.
For information on Supported Endpoint Types, see the Cisco TelePresence Multipoint Switch Administration Guide, which you can access at the following location:
http://www.cisco.com/en/US/products/ps7315/prod_maintenance_guides_list.html
TelePresence Call-in Number
Introduced in version 1.8 of Cisco TelePresence Multipoint Switch (CTMS) and Cisco TelePresence Manager (CTS-Manager), the Cisco TelePresence Call-in Number feature enables a Meeting Organizer to allow users to join the meeting from Cisco TelePresence endpoints that are not scheduled in the meeting invitation. With this feature enabled in the Configure > Applications Settings page, Bridges and Servers tab, in the CTS-Manager Administrative UI, the CTS-Manager communicates with the CTMS to obtain the CTMS multipoint call-in number and the meeting number, which is a unique identifier for the meeting. The meeting organizer then provides the participants with the call-in number to join the meeting from their endpoints. After calling in, the participants hear a voice prompt and enter the meeting number. The CTMS permits participants to join after they enter the meeting number successfully.
For complete information on this feature, see the "Cisco TelePresence Call-In Number," which you can access at this location:
http://www.cisco.com/en/US/products/ps7074/products_installation_and_configuration_guides_list.html
Note
UCS Server
CTMS release 1.8 can be installed and run on Cisco's new UCS server platform, the Cisco UCS C210 M2 server. Before installing CTMS software on a UCS C210 M2 server, you must configure the server and install VMWare.
Note
For UCS C210 M2 server specifications, see Table 4.
For information about setting up the server and installing the CTMS software, see the Cisco TelePresence Multipoint Switch Administration Guide, which you can access at the following location:
http://www.cisco.com/en/US/products/ps7315/prod_maintenance_guides_list.html
For information about migrating from a Cisco MCS server to another MCS server or a UCS server, see the Hardware Migration Guide for CTS-Manager, CTMS, and CTRS - Release 1.8, which you can access at the following location:
http://www.cisco.com/en/US/docs/telepresence/hw_migration/1_8/ct_hw_mig.html
Network Multipoint
Multiple CTMS devices can be deployed in a Cisco TelePresence topology. Starting with CTMS release 1.8, the network multipoint feature allows two CTMS devices to support endpoints during a static meeting.
The support of two CTMS devices during a network multipoint meeting provides these benefits:
•
•
•
The transition of a static meeting to a network multipoint meeting is made dynamically as the meeting begins. From the perspective of the meeting participants, the experience of attending a network multipoint meeting is the same as attending a non-network multipoint meeting.
For information on network multipoint, see the Network Multipoint Design Guide, which you can access at this location:
http://www.cisco.com/en/US/products/ps7315/products_implementation_design_guides_list.html
Event Recording
Event Recording lets you create recordings of meetings with multiple video and audio streams. You can choose which streams to record. This is useful for recording scripted corporate events, such as company meetings. The recording is initiated from the CTMS where you can control what is being recorded. After the recording is completed, you can find and download the recording from the CTRS.
Because the special events to be recorded are director-controlled and generally scripted, you can manage an Event Recording session from the Director Control UI in the CTMS Administrative UI only. The CTMS Administrative UI enables you to select the video and audio streams to record, start, pause/resume, and stop the recording of the event.
Note
After you finish recording an event, the recording is available for playback, sharing, downloading, and other tasks.
Note
For information on Event Recording, see the Cisco TelePresence Multipoint Switch Administration Guide, which you can access at the following location:
http://www.cisco.com/en/US/products/ps7315/prod_maintenance_guides_list.html
Browser Security
This new feature secures communication between the CTMS web server and the browser through which you access the CTMS Administrative UI. Browser security eliminates website security certificate warnings, which you receive if your web server is not secure.
Note
To implement browser security, you must buy a Secure Sockets Layer (SSL) certificate from a certificate authority (CA), then install it on the CTMS.
For more information on browser security, see the Securing Cisco TelePresence Products, Release 1.8:
http://www.cisco.com/en/US/products/ps8332/products_installation_and_configuration_guides_list.html
MXE Support Discontinued
In earlier versions of the CTMS release notes, CTMS 1.8 and MXE 5600 with limited interoperability was supported.
Based on recent testing, it has been determined that MXE 5600 interop with CTMS 1.8 or higher is a solution Cisco can no longer recommend to customers. As a result, support for Media Experience Exchange (MXE) 5600 is discontinued with CTMS and CTS-Manager 1.8 and 1.9.
Existing customers are encouraged to migrate to TelePresence Server for interop.
For options regarding MXE 5600, contact your Cisco account team or send an inquiry to Ravi Bansal via email: ravbansa@cisco.com.

CTMS Release 1.8 Caveat Reference
Table 7 summarizes caveats found in CTMS Release 1.8.
Caveats for CTMS Release 1.8
CSCtt44841
Symptom: When a CTS 1.6.x endpoint tries to join a Cisco WebEx-enabled scheduled meeting supported by a CTMS 1.8, the endpoint is dropped with the following alarm:
ALARM_INTEROP_NOT_SUPPORTED. Call not connected. The endpoint is unable to join the meeting because it does not support interoperability..
Condition: See Symptom.
Workaround: None.
Further Problem Description: The system message that displays does not specify the type of interoperability that is not supported. The call was dropped because the CTS 1.6.x endpoint does not support Cisco WebEx interoperability.
CSCuc05549
Symptom: CTMS crashes and is unable to process calls.
Condition: CTMS version 1.8.x. UDP is configured between Unified CM and CTMS.
Workaround: Change SIP trunk configuration between Unified CM and CTMS to TCP.
Further Problem Description: If UDP is set on the SIP trunk between Unified CM and CTMS, calls may not get processed.
CSCua83891
Symptom: When a CTS endpoint with 2048-bit security certificates tries to join a secure CTMS conference, it will be dropped. If it tries to join a scheduled (best-effort) meeting, the meeting and the endpoint will be downgraded to non-secure.
Condition: This affects the newer CTS which comes with manufacturer installed 2048-bit security certificates.
Workaround: Use best-effort or non-secure meetings.
CSCts99571
Symptom: System capacity is down to 34 ports with Cisco MXE Media Processing Modules.
Condition: Place 45 ports via MXE to a CTMS running software release 1.8.
Workaround: Use a CTMS running software release 1.7.x or earlier.
CSCtw78534
Symptom: Extend Multipoint Meetings and Start Meetings Early features do not work at the same time, so meetings cannot be started early or ended late.
Condition: Both Extend Multipoint Meetings and Start Meetings Early are enabled at the same time.
Workaround: None.
CSCtx69314
Symptom: Logs cannot be downloaded from the CTMS Administrative UI, and remote_account creation fails.
Condition: CTMS /common file system is set to read only. CTMS 1.8.0(1026) on MCS 7845-I2 that has been upgraded.
Workaround: None.
CSCtu33601
Symptom: "null" and `Go Back' are incorrectly displayed when changing device security to Non-Secure.
Condition: With CTMS in secure mode, go to Unified CM > SIP Profile Settings tab, change the Device Security from Secure to Non-Secure and click Apply.
Workaround: Click elsewhere in the CTMS Administrative Web UI and the setting is changed properly.
CSCtu03710
Symptom: Newly configured and upgraded secure CTS 1.8.x cannot join secure CTMS meeting.
Condition: In a rare situation with packet loss (such as in a bad network) the protocol of key exchange cannot finish between CTMS and CTS.
Workaround: Ensure the phone device configuration on Unified CM has Disable Speakerphone and Disable Speakerphone and Headset checked (enabled) and the PC Port option disabled, then retry joining the meeting from the endpoint.
CSCts99446
Symptom: The Director Control set eventcontrol entry source CLI command does not work as expected.
Condition:Director Controls are enabled, a meeting is started and the set eventcontrol entry source command is issued to lock new participants to seeing a specific existing participant. When a new participant joins, they do not see the existing participant as expected.
Workaround: None.
CSCts35244
Symptom: Adding a recording server results in a null pointer exception error in the CTMS web UI.
Condition: In the Configure > Recording Server page, click New and enter a value. Press Enter (instead clicking Save).
Workaround: Click Save instead of pressing Enter.
CSCtt70572
Symptom: An endpoint is allowed to join a meeting and the meeting is downgraded to a lower quality, even though Allow Downspeed is set to No on the Manage > Default Meeting Settings page.
Condition: Allow Downspeed is set to No on the Manage > Default Meeting Settings page of CTMS. An endpoint configured with quality of 1 MB joins a meeting with quality of 1.5 MB and the meeting downgrades to 1 MB.
Workaround: None.
CSCtu22309
Symptom: TelePresence Call-In Number prompts become squeaky.
Condition: If there are more than 5 endpoints, the prompts can become squeaky for new users joining the meeting via the TelePresence Call-In Number.
Workaround: None.
CSCtt20160
Symptom: Active speaker video switching from Movi (now called Jabber) taking more than 20 seconds in a multipoint call.
Condition: Establish the multipoint call using the CTS1000, EX90 and Movi keep switching the active speaker by speaking from each end point observe the video switch from Movi to other parties in the bridge.
Workaround: None.
CSCtl56527
Symptom: In a meeting with two single-segment endpoints and one triple-segment endpoint, the participants displayed by each single endpoint generally appear simultaneously in the center and left segments of the triple endpoint. However, in a network multipoint meeting, participants displayed by each single endpoint might compete to be displayed in the center segment of a triple endpoint, leaving the left and right segments blank.
Condition: This issue can occur if each single endpoint is supported by a different CTMS device in a network multipoint meeting. In this situation, each single endpoint is basically competing for the active speaker video in a triple endpoint, leaving the left and right segments blank.
Workaround: There is no workaround if no additional participants join the meeting. However, if more participants join, all segments of the triple endpoint will display participants.
Further Problem Description: This issue is a user experience issue in terms of optimally filling all segments of a triple endpoint. It does not affect any other functionality of the system.
CSCtl80292
Symptom: In a Commercial Express environment, after CTMS registers to CTS-Manager for the first time or after a new license application, the CTMS segment count is updated properly and shown on CTMS UI as expected. However, the updated CTMS segment count is not updated on CTS-Manager.
Condition: See Symptom.
Workaround: From the CTMS Administrative UI, register manually with CTS-Manager again. This action forces a segment update with CTS-Manager.
Further Problem Description:
1.
2.
3.
4.
5.
CSCto12827
Symptom: If an endpoint tries to join a locked CTMS meeting, Cisco Unified Communications Manager (Unified CM) may respond with "400 Bad Request" instead of "480 Temporarily Unavailable" or "486 Busy Here."
Condition: The described symptoms could occur under the following conditions:
•
•
Workaround: None. This issue will be fixed in an upcoming CTMS release.
CSCtq40875
Symptom: After a CTMS is added in the Configure > Bridges and Servers page of the CTS-Manager Administrative UI, the status of the CTMS in the CTS-Manager Admin UI is OK. However, a few minutes later, the CTMS goes into a critical error state.
Condition: See Symptom. This issue can occur if the CTMS and CTS-Manager are both running release 1.8.
Workaround: Clear the critical system messages related to this issue in the CTMS Administrative UI, Troubleshoot > System Messages page. This action should enable the CTMS to return to an OK state in the CTS-Manager Administrative UI.
CSCtr29759
Symptom: After starting an ad hoc meeting using the Manage > Ad-Hoc Meeting page in the CTMS Administrative UI, you click Cancel. However, this action does not stop the CTMS from dialing the endpoints.
Condition: This issue can occur if one or more of the endpoints added to the ad hoc meeting are already in a meeting.
Workaround: After the meeting is started, you can cancel the meeting, thereby freeing up the endpoints, by manually deleting each endpoint from the Manage > Active Meetings page.
CSCtr88752
Symptom: The video quality of a CTMS multipoint meeting is downgraded to 720p even though all endpoints in the meeting are CTS and support 1080p.
Condition: These symptoms might occur under the following conditions:
•
•
Workaround: Upgrade Cisco Unified CM release to 8.5.1 or later.
Further Problem Description: This issue applies only to Unified CM release 7.1 because this release does not handle multiple video PTs (Payload Types) in the SDP correctly. CTS sends two PTs in the order of 1080p and 720p in the SDP. Unified CM 7.1 always chooses the last one, in this case the PT of 720p and adds it to the SDP sent to CTMS. Unified CM release 7.1's method of handling multiple PTs causes CTMS to choose 720p resolution for the conference.
CSCtr92930
Symptom: An endpoint might suddenly be dropped from a meeting without record of the endpoint sending a SIP BYE message to the CTMS, although the CTMS received the SIP BYE message from the endpoint.
Condition: This issue is caused by Cisco Unified Communications Manager (Unified CM) sending the SIP BYE message on behalf of the endpoint. This behavior is the result of a Unified CM caveat, which affects the handling of the SIP SESSION TIMER expiry. This Cisco Unified CM issue is tracked by CSCts04421.
Workaround: The SIP SESSION TIMER is normally set to 1800 (seconds). To avoid this issue (until a fix is officially released for Unified CM), the SIP SESSION TIMER should be increased to the maximum value, which is 86400 (seconds) (or 1 day).
Further Problem Description: To set the Unified CM SIP SESSION TIMER to 86400 seconds:
1.
2.
3.
4.
5.
CSCts58516
Symptom: You enter the set logging disable CLI command, but it does not disable logging.
Condition: This command does not work in CTMS releases 1.6, 1.7, and 1.8 for the user account.
Workaround: None. This command will be removed from an upcoming CTMS release.
CSCts73135
Symptom: The CTMS Administrative UI is no longer reachable, and the browser provides an error message, which says that the certificate has been revoked.
Condition: This situation can occur if the SSL certificate you bought from a Certificate Authority expires while the browser security feature is enabled on the CTMS.
Workaround: Log into the CTMS Administrative command-line interface (CLI) and use the set web-security command to generate a self-sign certificate that allows you to resume logging into the CTMS Administrative UI. For information on how to use this command, see the Cisco TelePresence Multipoint Switch Release 1.8 Command Reference at:
http://www.cisco.com/en/US/products/ps7315/prod_command_reference_list.html
When you are able to log into the CTMS Administrative UI again, go to the Configure > Security page, set Browser Security to "Non-Secure," and click Apply.
After disabling browser security, you must decide whether to install a new SSL certificate or to keep browser security disabled. For information on installing a new SSL certificate, see the Cisco TelePresence Multipoint Switch Release 1.8 Administration Guide, which you can access at:
http://www.cisco.com/en/US/products/ps7315/prod_maintenance_guides_list.html
CSCtt02782
Symptom: After upgrading the CTMS from release 1.7 to 1.8, secure calls are not being completed.
Condition: This issue can occur if the following sequence of events occurs:
1.
2.
3.
Workaround: To work around this issue, do the following:
1.
–
–
–
2.
3.
CSCtt15171
Symptom: The time displayed in the Media Snapshot dialog box corresponds to the location of the CTMS server instead of the location of the CTMS administrator.
Condition: This issue occurs when accessing the Media Snapshot dialog box for an active meeting on a CTMS running any release.
Workaround: If the CTMS server and administrator are in different time zones, convert the time as appropriate.
CSCtt42155
Symptom: After launching a Cisco TelePresence WebEx meeting using One-Button-to-Push, the presenter in Room A passes the ball to a presenter in Room B. However, the Cisco WebEx Video View window continues to display "Viewing Room A's desktop" as well as the WebEx ball next to Room A.
Condition: The described symptom may occur if the presenter in each room still has the presentation cable connected to their laptop.
Workaround: The presenter in each room should disconnect the presentation cable from their laptop, then the next presenter should reconnect the cable to their laptop.
CSCtt22558
Symptom: Occasionally, the cimlistener process produces a core dump under /var/log/active/core.
Condition: The core dump can occur at any time.
Workaround: The core dump is benign, and the cimlistener process restarts itself afterward. To remove core dump(s) that may accumulate, you can set up a cron job that periodically removes them.
CSCtt28939
Symptom: When installing the CAPF root certificate on the CTMS, an error message appears saying that the file is the CTM-trust file.
Condition: This situation can occur under the following conditions:
•
•
C:\Documents and Settings\Administrator\Desktop\CUCM\CAPF.der
Workaround: Remove or rename any path elements that contain the string "CUCM".
Fixed: 1.8.1
CSCtt20570
Symptom: During a Cisco TelePresence WebEx meeting, the Cisco WebEx Video View window sometimes displays an inaccurate active speaker on the top left corner of the Video display.
Condition: See Symptom.
Workaround: None.
Fixed: 1.8.1
CSCtt44841
Symptom: When a CTS 1.6.x endpoint tries to join a Cisco WebEx-enabled scheduled meeting supported by a CTMS 1.8, the endpoint is dropped with the following alarm:
ALARM_INTEROP_NOT_SUPPORTED. Call not connected. The endpoint is unable to join the meeting because it does not support interoperability.
Condition: See Symptom.
Workaround: None.
Further Problem Description: The system message that displays does not specify the type of interoperability that is not supported. The call was dropped because the CTS 1.6.x endpoint does not support Cisco WebEx interoperability.
CSCtu07635
Symptom: In a CTMS 1.8 multipoint meeting, the video sent by a third-party TelePresence Interoperability Protocol Version 7 (TIPv7) unrestricted endpoint might not be seen on a CTS 1.8 endpoint.
Condition: CTMS 1.8 does not properly support third-party TIPv7 devices indicating unrestricted media transmission in multipoint meetings with CTS 1.8 and earlier endpoints.
Workaround: None. This issue will be resolved in an upcoming maintenance release.
Fixed: 1.8.1
New and Changed Information for CTMS Release 1.7.2
Video Quality for Scheduled Meetings
In CTMS releases before 1.7.2, the video quality of a scheduled multipoint meeting was determined by the endpoint with the lowest video quality.
Release 1.7.2 introduces an enhanced approach to determining the video quality of a scheduled meeting. From the list of scheduled participating endpoints, CTMS now determines the endpoint with the highest video quality and sets the meeting to that quality.
The video quality of a scheduled meeting is also affected by the setting of the Allow Downspeed attribute, which can be accessed in the Default Meeting Settings page of the CTMS Administrative UI. By default, this attribute is set to Yes, which means that if an endpoint with lower video quality joins a higher quality meeting, CTMS adjusts the quality of all endpoints to match the lower quality endpoint. If the parameter is set to No, an endpoint with a lower video quality is not allowed to join the meeting because of the quality mismatch.
Quality Value Displayed in Active Meetings Page
As a result of the video quality enhancements described in the "Video Quality for Scheduled Meetings" section, the value of the Quality attribute displayed in the Manage > Active Meetings page has been updated in CTMS 1.7.2. This attribute now displays the current meeting quality, factoring in the dynamic changes made by the CTMS as endpoints join and leave the meeting, and per the setting of the Allow Downspeed attribute.
Cisco WebEx User Password Expiration or Reset
A user's Cisco WebEx password can expire, or the Cisco WebEx administrator might reset their password but they never use the new password. If either of these events occurred and the user tries to start a scheduled multipoint meeting with Cisco WebEx, the phone UI displays this message:
WebEx account issue, please check your WebEx account
After receiving this message, the user must specify a new Cisco WebEx password as follows:
•
•
After specifying a new password, the user should be aware of the following points:
•
•
Cisco WebEx Via Proxy Server
Note
To maintain the Cisco WebEx server's anonymity, a precaution that provides an additional layer of security, you can set up a proxy server through which the CTMS and Cisco WebEx TelePresence gateway communicate.

Condition: This issue can occur if an endpoint dials in early to join a scheduled meeting.
Workaround: None. This issue does not affect the meeting itself.
CSCtn79160
Symptom: The audio portion of a Cisco TelePresence WebEx OneTouch meeting does not work. Also, when a meeting participant dials into a CTMS Direct Inward Dial (DID) number, they don't hear multiple beeps, which indicate a good connection.
Condition: See Symptom above.
Workaround: Restart the CTMS processes using the Troubleshoot > Process Status page.
CSCtn89016
Symptom: Unable to successfully issue utils service snmp commands in the CTMS command line interface (CLI). After entering any of the SNMP commands, the CLI prompts you for a password. After entering a single character, the SSH session hangs.

CSCtf51649
Symptom: In the Troubleshoot > Log Files page of the CTMS Administrative UI or under the /var/log/active/core directory, you notice one or more core files such as "core.10118.8.cimlistener.1289229932."
Condition: You might notice these core files after upgrading the CTMS software from version 1.6.x to version 1.7.x or 1.7.0.x.
Workaround: The cimlistener process might generate core files if SNMP traps are configured. These files are benign and do not affect any operations. Therefore, no action is required.
CSCti08961
Symptom: In the Configure > CTS Manager page of the CTMS Administrative UI, you enter a name for the User attribute that includes a blank space(s) before or after. In the Configure > Bridges and Servers page of the CTS-Manager Administrative UI, you add the same name, including the blank space(s). After refreshing the Configure > CTS Manager page in the CTMS Administrative UI, you notice that the Registration Status field says "Fail to register," while in the Configure > Bridges and Servers page of the CTS-Manager Administrative UI, the Status for the CTMS is "Error."
Condition: See Symptom above. Additionally, the CTMS is running build 1.7.0.1 and CTS-Manager is running build 1.7.0.2.
Workaround: Remove the blank space(s) from the username in the CTMS and CTS-Manager configurations.
CSCti31875
Symptom: In a multipoint meeting with 1.5.x or 1.6.x CTS endpoints trying to present, users may see a black presentation window or screen when the call is resumed after it was on hold.
Condition: This issue can occur when CTS endpoints running different software versions (1.5.x or 1.6.x) are in a meeting and the active presenter role changes from one endpoint to another. If a presentation stream is active and a 1.5.x or 1.6.x CTS endpoint connects its presentation cable, the active stream will change. If the newly active presenter places the call on hold, the previous presenter will resume its presentation stream. When the 1.5.x or 1.6.x endpoint resumes the call, a black presentation window or screen could appear.
Workaround: Disconnect then reconnect the presentation cable on the endpoint that resumed the call to retry the role of active presenter.
CSCtj92963
Symptom: A static multipoint meeting cannot be started.
Condition: On the CTMS, the set holdresume CLI command is set to false.
Workaround: Set the holdresume command to true, which is the default setting.
CSCtk58352
Symptom: After entering the URL of a CTMS in a supported browser, the Login page of the CTMS administrative GUI does not appear.
Condition: This issue can occur after upgrading a secure CTMS from software version 1.6.x to 1.7.x and deleting all security certificates.
Workaround: Perform the following steps:
1.
2.
3.
CSCtk53578
Symptom: During a secure multipoint meeting, a CTS endpoint does not display video nor receive audio.
Condition: The DTLS key exchange fails, and as a result, secure calls fall back to SDP mode.
Workaround: Reboot the CTS endpoint.
New and Changed Information for CTMS Release 1.7.0
Cisco TelePresence WebEx OneTouch
The Cisco TelePresence WebEx OneTouch bridging solution integrates the Cisco WebEx conferencing server with Cisco TelePresence multipoint meetings. When the first CTS endpoint connects to a meeting, the CTMS automatically connects with the Cisco WebEx conferencing server. The presentation and audio are automatically shared.
Cisco Media Experience Engine Interoperability
CTMS release 1.7 supports the Cisco Media Experience Engine (MXE), which provides interoperability between video conferencing (VC) endpoints. The MXE acts as a transcoder for the VC endpoints that want to join a TelePresence multipoint meeting or dial directly to a CTS endpoint.
All scheduled MXE meetings that include one or more CTS endpoints are multipoint and therefore involve the CTMS.
The following are caveats for interoperability with the MXE in CTMS release 1.7:
•
•
•
•
•
•
Cisco Unified Videoconferencing 7.1 and Cisco Unified Videoconferencing Manager Interoperability
CTMS release 1.7 supports interoperability with Cisco Unified Videoconferencing (CUVC) 7.1 and CUVC Manager (CUVC-M).
The following are caveats to interoperability with a CUVC when a Cisco Tandberg Video Communication Server (VCS) is used to dial in to the CUVC:
•
If this condition occurs, you must reboot the CUVC to restore service and place calls directly from Cisco Tandberg endpoints to the CUVC.
•
Director Controls in the CTMS Web UI
Director Controls, one of several ways to set what rooms and room segments in active meetings see and hear, was available only through the CLI in CTMS release 1.6. In CTMS release 1.7, Director Controls functionality is also accessible through the Web user interface after the feature is enabled through the CLI.
Dual-Presentation Streams
CTMS release 1.7 introduces additional quality when a Presentation Codec (CTS-HFR-COLLAB) is used. If an endpoint that is presenting includes this optional codec, two presentation streams are sent. Depending on the capability of the participating endpoints, both streams are sent at 5 frames per second (FPS) and 30 FPS, or at 1 FPS and 30 FPS. This feature adds approximately 500 kbps bandwidth to a call.
Conference Control Protocol for Web Services
CTMS uses Conference Control Protocol (CCP) to provide CTS endpoints with access to in-meeting functions, such as the participant list; room or speaker switching policies; and the lock meeting feature. CCP is delivered over HTTP or HTTPS and can be forwarded to HTTP proxies in a secure enterprise domain where direct HTTP Internet access is not possible.
Reverse Message Polarity (Smart Media)
Reverse Message Polarity (RMP), also known as Smart Media, provides CTMS with a way to classify the quality of video streams. These streams can then be targeted for quality adjustments.
Meeting Termination and Extension Policy and CTMS Resources
A meeting organizer or participant might want to extend a scheduled meeting beyond its scheduled end time. CTMS has a limited number of audio and video resources, so the CTS-Manager (CTS-Man) administrator must create a policy that determines how the CTMS handles termination and extension. This policy indicates who can extend and for how many minutes.
The CTMS administrator does not have to configure anything for meeting termination and extension to work. The CTMS accepts the configured policy from the CTS-Man and handles CTMS resources according to that policy.
Manageability Improvements
Troubleshoot > System Messages in the CTMS web interface provides a list of messages about CTMS events or conditions that might affect the performance of endpoints in a multipoint meeting. In CTMS release 1.7, a column called "Recommendation" has been added to this list page. When appropriate, a message includes a recommendation for troubleshooting the cause of the event or condition.
TIP Support
CTMS release 1.7 supports Telepresence Interoperability Protocol (TIP) version 6.0 and version 7.0.
Cisco TelePresence Commercial Express Version of CTMS Release 1.7
The Cisco TelePresence Commercial Express product bundle is delivered as a single Cisco MCS server with one or more Cisco TelePresence application DVDs, license keys, and instructions to install the product, including the recommended VMware configuration. During installation, the common infrastructure component within the Cisco applications detects the VMware and identifies it as supported hardware.
Once you have VMware installed on your system, the basic procedure to install CTS-Manager, CTMS, and CTRS are the same. You can install the CTMS and CTRS in any order once you have installed, configured, and set up licensing for CTS-Manager.
For Commercial Express versions of CTMS, the number of schedulable segments and the number of ad hoc and static segments is determined by the Commercial Express license, which is loaded in CTS-Manager. After you have set up licensing in CTS-Manager, the CTMS administrator can reconfigure the number of ad hoc and static segments to any number less than the total number of permitted segments.
Interoperability Issues
When endpoints that use a Cisco/Tandberg VCS system as a proxy dial into a CUVC running version 7.1, the CUVC audio mixer might terminate, which results in audio failure. CTS endpoints in an Interop meeting with CUVC 7.x might not see or hear video conference callers. These callers might not connect to CUVC or might be connected without audio. SIP calls are rejected with SIP return code "603 declined." This conditions occurs with or without CUVC-M in the call path.
If this condition occurs, you must reboot the CUVC to restore service and place calls directly from Cisco Tandberg endpoints to the CUVC.
This condition is noted in CSCth61621: CUVC rejects new calls when VCS is used as a proxy.

CSCtb64811
Symptom: The graphs in the Troubleshoot > System Resource page do not display any data.
Condition: This issue can occur after a network interface card (NIC) failover.
Workaround: Approximately 10 hours after the NIC failover, the System Resource page will start to work properly and display data again.
CSCtc68768
Symptom: Deleting the DNS and Domain Name values causes an error message to appear.
Condition: In the System Settings > IP page, if you remove the values for the DNS and Domain Name fields and click Apply, the following error message displays: Domain Name "is not a valid value."
Workaround:
To remove the DNS, perform these steps:
•
•
•
The DNS is removed after the CTMS is restarted.
CSCtf73377
Symptom: The CTS endpoint displays a blank presentation screen.
Condition: This issue can occur under the following conditions:
•
•
•
•
•
Workaround: On CTS endpoint C, unplug the presentation cable, then plug it back in.
Further Problem Description: This issue can occur if a CTS endpoint plugs in at 30 FPS presentation at the same time that another endpoint, which initially received the call at 5 FPS presentation, resumes the call. After this sequence of events, the CTMS and CTS can become unsynchronized as to the correct framerate of the presentation. Unplugging then replugging the presentation cable causes the CTMS and CTS to reestablish synchronization.
CSCtf82182
Symptom: The CTMS administrative GUI displays two identical warning messages for the MXE.
Condition: These messages can display if the MXE is rejected while trying to join a locked meeting.
Workaround: None.
CSCtg07495
Symptom: For a 1.6.x CTS endpoint, the MXE call statistics indicate more bandwidth than the CTS call statistics.
Condition: This discrepancy can occur for calls between a CTS 1.6.x and VC endpoint through the MXE.
Workaround: None.
CSCtg50877
(Duplicate of CSCti94915)
Symptom: Occasionally, at the beginning of a best-effort ad hoc meeting, a secure CTS endpoint may display a black screen with a secured call icon and no video.
Condition: This issue can occur under the following conditions:
•
•
Workaround: Redial that endpoint into the meeting.
CSCth44072
Symptom: A Meet-Me meeting participant, who is on hold, is dropped from the meeting.
Condition: In a Meet-Me meeting, if the caller is the only participant in the meeting and places the meeting on hold, the caller is dropped by the CTMS with the cause code 34.
Workaround: The participant must call back into the meeting.
CSCth51888
Symptom: A bulk event control request for a large meeting may generate errors. As a result, multiple alarms with the message "Failed to send msg: errno=11, errorstr=Resource temporarily unavailable" are logged into the CTMS administrative GUI.
Condition: If an event control administrator tries to modify all endpoints in a large event (using all 48 segments) in CTMS version 1.7, the alarm messages described in "Symptom" may be observed.
Workaround: Modify a small subset of endpoints at a time (<25) instead of updating all endpoints at the same time.
CSCth93803
Symptom: WebEx meetings do not start properly.
Condition: This issue can occur under the following conditions:
•
•
Workaround: After entering the correct address in the WebEx TelePresence Gateway URL field, restart the CTMS processes to force the system to accept the correct address.
CSCti14371
Symptom: In the CTMS administrative GUI, a single-segment endpoint, which was originally set as a presenter, is still shown as the presenter in a meeting that has no boardroom.
Condition: This issue can occur under the following circumstances:
•
•
•
•
•
Workaround: Manually remove the role of presenter from the single-segment endpoint, or select a new boardroom then select a new presenter.
CSCti16462
Symptom: Due to a misconfiguration, the CTMS is unable to place a call.
Condition: This issue can occur if the Unified CM1, Unified CM2, and Unified CM3 fields in the Configure > Unified CM page specify invalid or non-working Unified CMs. Under this condition, the CTMS uses the Unified CMs specified in the Unified CM4 and Unified CM5 fields, which are not supported.
Workaround: Specify valid and working Unified CMs in the Unified CM1, Unified CM2, and Unified CM3 fields.
CSCti21782
Symptom: In the Configure > Security page, the administrator clicks the Delete All or Download LSC button, and the following occurs:
•
•
Condition: These issues can occur if accessing the Configure > Security page when using a Mozilla Firefox browser.
Workaround:

•
CSCti21821
Symptom: After the system finishes downloading all log files, you change one or more log levels and the system unexpectedly prompts you to download all log files again.
Condition: This issue can occur under the following conditions:
•
•
•
Workaround: To complete the task of changing the log levels, re-access the Log Files page by clicking "Log Files" in the left navigation pane, change the log levels, then click "Apply."
CSCti26725
Symptom: In the Manage > Active Meetings page, a user deletes a large meeting with 20 or more rooms but notices that a few of the rooms are not yet deleted.
Condition: The issue can occur if the user is accessing the Manage > Active Meetings page with a Mozilla Firefox browser.
Workaround: Refresh the Firefox browser.
CSCti31875
Symptom: In a multipoint meeting with 1.5.x or 1.6.x CTS endpoints trying to present, users may see a black presentation window or screen when the call is resumed after it was on hold.
Condition: This issue can occur when CTS endpoints running different software versions (1.5.x or 1.6.x) are in a meeting and the active presenter role changes from one endpoint to another. If a presentation stream is active and a 1.5.x or 1.6.x CTS endpoint connects its presentation cable, the active stream will change. If the newly active presenter places the call on hold, the previous presenter will resume its presentation stream. When the 1.5.x or 1.6.x endpoint resumes the call, a black presentation window or screen could appear.
Workaround: Disconnect then reconnect the presentation cable on the endpoint that resumed the call to retry the role of active presenter.
CSCti38768
Symptom: The video on a WebEx Common Intermediate Format (CIF) video screen freezes momentarily.
Condition: This issue can occur when a new CIF video source is switched to WebEx.
Workaround: This issue resolves itself within a few seconds. No action is required.
CSCti53470
Symptom: A scheduled meeting using one-button-to-push dialing may cause the following CTMS error:
Call can't connect, no active meeting error
Condition: This error can occur if the meeting organizer left the Subject field blank while setting up the meeting in the email client.
Workaround: The meeting organizer should update the meeting with a subject.
Further Problem Description: CTMS does not allow a meeting with a blank Subject field. Although the meeting is scheduled successfully in the email client and CTS-Manager, the conference cannot be started from CTMS, which results in the error message.
CSCti58167
(Duplicate of CSCti14371)
Symptom: Presenter remains set even though it left and rejoined a boardroom meeting.
Condition: An endpoint that was originally set as the presenter in a boardroom leaves then rejoins the meeting. However, the CTMS Administration UI still shows this endpoint as the presenter.
Workaround: Unset that specific presenter if the presenter is in the boardroom, or select a different presenter.
CSCti62790
(Duplicate of CSCti38768)
Symptom: The System Messages page displays several instances of the following INFO-level message: ALARM_MEDIA_SSRCSWITCH_NOTIDR
Condition: This issue can occur in Interop and WebEx meetings when stream switches are frequent. Despite the frequent messages, this condition is benign, and there will be no impact to the audio or video quality of a meeting.
Workaround: Currently, there is no workaround for this issue. To remove the messages from the System Message page, the administrator can select each instance of the message, then click "Clear" at the bottom of the page. Alternatively, they can click "Clear All" to hasten the process; however, this method is not advised as other messages may inadvertently be removed from the page. Neither of these methods will affect the log files in any way.
CSCti62824
Symptom: A meeting ended at its scheduled time, but according to a system message that appeared in the CTMS administrative UI, the meeting was extended past its scheduled end time.
Condition: This issue can occur if a meeting could be extended, but was not.
Workaround: The scenario described in Symptom is benign, and no action is required.
CSCti89282
Symptom: The participant list displays multiple grayed-out VC endpoints.
Condition: When there is more than one active VC Room in a scheduled meeting, this condition can occur.
Workaround: None.
CSCti91916
Symptom: After downloading the Locally Significant Certificate (LSC), reloading the CTMS does not restart the processes.
Condition: Processes are STOPPED after you download the LSC and the CTMS is automatically reloaded.
Workaround: Either manually restart the processes, or select one of the encrypted device security settings from the Unified CM > SIP Profile Settings tab.
CSCti94915
Symptom: An endpoint is dropped from a meeting.
Condition: The CTMS' conference manager may have sent RMP EFC messages when the endpoint was in a state other than the connected state, for example, the hold state. If the conference manager sends these messages while the endpoint is in, for example, the hold state, the endpoint could be dropped from the meeting.
Workaround: Meeting participants should redial that endpoint back into the meeting.
CSCti96592
Symptom: Although a space is an invalid character for an Access Management password, the system currently accepts one or more spaces in these passwords.
Condition: The system currently accepts spaces in Access Management passwords that are being created or updated.
Workaround: In future releases, the system will not accept a space in new and updated Access Management passwords. To accommodate the future enforcement of this invalid character, we recommend that you not use a space in Access Management passwords even though the system currently accepts it.
CSCtj57730
Symptom: After upgrading the CTMS from 1.6.1 to 1.7.0, static meetings with a security policy of Best Effort change to a security policy of Non-Secure.
Condition: In the 1.6.1 CTMS Administrative UI/Unified CM page/SIP Profile Settings tab, Device Security is set to Non-Secure, and Media Encryption is selected.
Workaround:

CSCtj82894
Symptom: The first participant dials across a non-secure intercluster Cisco Unified CM trunk into a secure or best effort meeting on a CTMS that is hosted by Unified CM version 8.0.3 or above. The CTMS is configured with "Encrypted with SDP Keys." When a second participant dials in (could be from anywhere), the first participant is dropped from the meeting and the second participant is put into remote hold by CTMS.
Condition: See Symptom.
Also, the CTMS is secured with Unified CM and uses the "Encrypted with SDP Keys for 8.0.3 Cisco Unified CM" setting for the Device Security attribute in the Unified CM page/SIP Profile Settings tab.
Workaround: On the CTMS, choose the "Encrypted without SDP Keys" setting for the Device Security attribute in the Unified CM page/SIP Profile Settings tab.
CSCtj97946
Symptom: After the CTMS software is upgraded, the setting of the Time Zone attribute in the CTS-Manager page of the CTMS Administrative UI changes from its configured setting to "UTC - Coordinated Universal Time." CTS-Manager uses the Time Zone value to select this closest CTMS for the scheduled meetings. The inadvertent changing of this attribute to "UTC" can in turn cause CTS-Manager to select a CTMS that is not the closest.
Condition: This issue can occur under the following conditions:
•
•
Workaround:

Workaround: None.
CSCtk09141
Symptom: When adding a third endpoint to an intercompany multipoint call, one of the endpoints is dropped.
Condition: The CTMS is running release 1.7.0 software, and the Cisco GSR router is running release 3.7.1 software.
Workaround: When the third endpoint attempts to join the call, place the call on hold then resume it within 5 seconds if possible.
CSCtl91785
Symptom: During a multipoint meeting with Auto Lecture Mode enabled, endpoint A is the active speaker and receives a scrolling view of all participants. After Auto Lecture Mode is disabled, endpoint A continues to receive the scrolling view of all participants.
Condition: See Symptom. This issue can occur if the CTMS is running release 1.7 software.
Workaround: On endpoint A, place the call on hold, then resume it. This action should disable the scrolling view.
CSCtl91785
Symptom: During a multipoint meeting with Auto Lecture Mode enabled, endpoint A is the active speaker and receives a scrolling view of all participants. After Auto Lecture Mode is disabled, endpoint A continues to receive the scrolling view of all participants.
Condition: See Symptom. This issue can occur if the CTMS is running release 1.7 software.
Workaround: On endpoint A, place the call on hold, then resume it. This action should disable the scrolling view.
New and Changed Information for CTMS Release 1.6.4
Support for Non-CABAC Endpoints
CTMS 1.6.4 supports endpoints that do not use the context-adaptive binary arithmetic coding (CABAC) mechanism when encoding video. Those endpoints must indicate through Media Options signaling in the Telepresence Interoperability Protocol (TIP) that they are not using CABAC.
CTS endpoints must run software version 1.6.5 or later to support endpoints that do not use CABAC in meetings with CTMS.

New and Changed Information for CTMS Release 1.6.0
Upgrading to CTMS Release 1.6.0
When upgrading to CTMS Release 1.6.0, you must be running CTMS Release 1.1.2 or later. If you are running a version earlier than CTMS Release 1.1.2, update to CTMS Release 1.1.2 before upgrading to CTMS Release 1.6.0.
Standard Event Controls: VIP Mode, Auto Lecture Mode, and Boardroom Mode
In addition to VIP Mode, which was supported in previous releases, CTMS Release 1.6.0 supports Auto Lecture Mode and Boardroom Mode. All modes enable the CTMS administrator to manage the audio and video for specific events.
•
With CTMS Release 1.6.0, CTMS supports Auto Lecture Mode. When Auto Lecture Mode is enabled for a particular multipoint meeting (using the CTMS administrative GUI), the first speaker or room speaking uninterrupted for 60 seconds (60 seconds is the default) becomes the "lecturer." In Auto Lecture Mode, all sites see the "lecturing" speaker or room based on the switching policy (room or speaker). The lecturing site sees a scrolling view of all rooms in the meeting; a new room is displayed every 10 seconds (10 seconds is the default). During the meeting, if someone other than the lecturer speaks for approximately 2 seconds (approximately 2 seconds is the default), the lecturer is reset and the meeting returns to its standard switching policy. A lecturer is set again as soon as someone speaks uninterrupted for 60 seconds.
You can customize the Auto Lecture Mode default times by entering the set damping command in the CTMS admin CLI. See the CTMS release 1.6 command reference for information about this command:
http://www.cisco.com/en/US/products/ps7315/prod_command_reference_list.html
•
With CTMS Release 1.6.0, CTMS supports Boardroom Mode through the CTMS administrative GUI. Boardroom Mode allows for a highly customized boardroom configuration. When Boardroom Mode is enabled for a particular multipoint meeting, the administrator must first set a room as the boardroom. Then the administrator can specify presenters. The boardroom must use a CTS 3x00. Boardroom Mode must be enabled through the CTMS administrative CLI in order to use this feature from the CTMS administrative GUI.
Professional Event Controls: Director Controls Through the CTMS Administrative CLI
With CTMS Release 1.6.0, CTMS supports Director Controls. Director Controls allow an administrator to control any or all of the media options available for any multipoint meeting. Large events or scripted meetings often require manual mapping and locking of video and mapping or muting of video on a per-segment basis. With Director Controls, an advanced administrator can script and control large multipoint meetings. CTMS release 1.6 provides Director Controls through the CTMS admin CLI. See the CTMS release 1.6 command reference for a complete list of commands:
http://www.cisco.com/en/US/products/ps7315/prod_command_reference_list.html
Note
High Definition Interoperability
With CTMS Release 1.6.0, Cisco TelePresence supports high definition interoperability between Cisco TelePresence systems and other video conferencing/video telephony endpoints using the Cisco Unified Videoconferencing 5230 MCU using CUVC Release 7.0 software (CUVC 7.0).
Note
Note
Extended Reach
With CTMS Release 1.6.0, you can enable or disable Extended Reach (the default is enabled). With Extended Reach enabled, if a T1 endpoint joins a meeting, Conference Manager downgrades the meeting quality to 720p Lite. T1 endpoints are kept in the meeting, but pre-1.6 endpoints are dropped. If you disable Extended Reach, Conference Manager rejects incoming T1 endpoints. Pre-1.6 endpoints are kept in the meeting.
The CTMS admin CLI to enable or disable Extended Reach is set t1mode {true | false}, where true mean enable and false means disable.

Caveats for CTMS Release 1.6.0
CSCsw50200
Symptom: A lock can be placed on a hosted meeting and not allow the host to join.
Condition: For a hosted meeting, a participant can 'lock' the meeting from the phone UI and prevent the host from joining the meeting. When the host tries to join the meeting, the host gets a message stating the meeting is locked. The host cannot join.
Workaround: The administrator or meeting participant must first unlock the meeting so that the host can join.
CSCtc43708
Symptom: Call drops during interop MP meeting.
Conditions: 1. Packet loss introduced from legacy stream. 2. Large NTP time updates (this is a rare occurrence).
Workaround: None.
CSCtc68768
Symptom: Deleting DNS and Domain Name will give an error message
Conditions: On System Settings -> IP Settings page, if you remove the DNS and Domain Name fields and click Apply, an error message box shows with: Domain Name '' is not a valid value.
Workaround: To remove DNS altogether, leave the Domain Name field and just remove the DNS entries and Apply. When the CTMS restarts, there will be no DNS.
CSCtc71031
Symptom: Call drops. And CTMS alarm page shows SPIMAP timeout
Conditions: It only happens when at the time of the call join, another meeting which has lots of room joins and leaves activity, which is not likely to happen in real world, is ending.
Workaround: Redial the meeting.
CSCtc85023
Symptom: A false alarm is raised during a meeting when adding an older endpoint and afterward that same endpoint drops from the meeting.
Condition: During a meeting with one active speaker, when an older endpoint joins or is added (LTRP is turned off) and that same older endpoint is then dropped or drops from the meeting (LTRP is turned back on), this false system error WARN alarm is displayed: CTMS_ALARM_MEDIA_LTRP_REPAIR_MISMATCH.
Workaround: This alarm does not impact the meeting.
CSCtc88319
Symptom: 1080p quality selection is not available after changing Interop selection to No in the Static Meetings detail screen.
Conditions: User wants to change an existing Interop (1080p or 720p) static meeting to non-Interop 1080p meeting. In the Static Meetings popup window, after selecting No for Interop, the Quality droplist only shows 720p.
Workaround: Select the 720p quality (even though 1080p is desired) and click Save. Then select the same static meeting again and change the quality to 1080p.
CSCtd11725
Symptom: Change Security Policy back to Non-Secured will also change all static meetings to Non-Secured.
Conditions: After securing a CTMS, the Security Settings Meeting Security Policy can be changed. If this is changed from Non-Secure, and static meetings with Best-Effort and Secured Policies are created, if this the Security Settings Meeting Security Policy is changed back to Non-Secure, the static meetings will also be changed to Non-Secure.
Workaround: Edit each static meeting to set Meeting Security Policy to Best-Effort and Secured.
CSCtd29406
Symptom: Upgrade does not populate Dial Suffix for HD Interoperability
Conditions: Dial Suffix for HD Interoperability is a required field for the Default Settings page, but after an upgrade from a pre-1.6 CTMS version, this field is left blank.
Workaround: Manually input #*#000 in the Dial Suffix for HD Interoperability field.
CSCtl84403
Symptom: In the Configure > CTS-Manager page of the CTMS administrative UI, the Registration Status is "Not yet registered" even though scheduled multipoint meetings can be pushed to CTMS.
Conditions: This issue can arise if the CTMS sustained a loss of power. As a result, Trigger Registration from CTS-Manager fails to register.
Workaround: To force the registration, you can make a minor modification in the Configure > CTS-Manager page, and click Apply.
CSCtn27679
Symptom: The snmpwalk application queries the SNMP OID 10.3.3.17 1.3.6.1.4.1.9.1.587 on the CTMS, which in turn causes the CTMS SNMP service to become disabled.
Conditions: This issue might occur in rare through currently unknown conditions if the CTMS is running software version 1.6.3.
Workaround: Restart the CTMS SNMP service using the utils service snmp start command in the CTMS command-line interface (CLI).
