Open Caveats from CTMS Release 1.0.3(8)
•CSCsj29837 - CTMS scheduled meeting information should include switch and quality policies
Summary: Because the switch policy can be configured and modified on Cisco TelePresence Manager for scheduled meeting, the CTMS display for scheduled meetings should have the switch policy information and quality of conference used information on the detail page.
Status: Opened; no current workaround.
Closed and Resolved Caveats from CTMS Release 1.0.3(8)
•CSCsi16039 - Log Files: Change the name of the "Download All" button
Summary: In Log Files window, after using the filter button, the only choice that the user has is he button labeled "Download All." "Download All" implies that all of the log files will be downloaded, not the files that are the result of the filtering. The recommendation is to change "Download All" to "Download File(s) Listed."
•CSCsi24160 - Clicking "Filter" applies changes to Log Levels
Summary: From the Log Files window, if you select "New Log Level" for one process and then click "Filter,' the result is that the Log Level is automatically applied and the Apply and Reset buttons are grayed out. The Log Level should not be applied until the user clicks "Apply."
•CSCsi45541: Inconsistent use of rooms vs. segment in CTMS Administration software
Summary: In System Configuration, under System Settings, on the Resource Management window, parameters refer to "segments." In Meeting Management, on the Default Settings page, parameters refer to "rooms," "sites," and "segments." The recommendation is to standardize on "segments."
•CSCsi49322 - Active Meeting Status window should move to the front of CTMS WebUI
Summary: If you create an AdHoc meeting with maximum rooms, and then add another room, the Active Meeting Status window is displayed, showing the error. If you click on the CTMS WebUI screen without closing the Active Meeting Status window, the Active Meeting Status window moves to the background. If you try to add another room, the Active Meeting Status window updates but stays in the background.
•CSCsi51051 - Pages take a long time to refresh
Summary: The WebUI is now taking a very long time—1 to 2 minutes—to refresh. Only the web status bar at the bottom of the screen shows that the page is refreshing.
•CSCsi51283: Logs and System Error displays incorrectly when choosing "Rows per Page"
Summary: System Errors and Log files list 10 errors or files per page. If you have more than 10 errors or files, when you click "Last," those beyond the initial 10 errors or files are displayed on another (last) page. If you click "Rows per Page" and choose anything greater than 10, the system does not increase the number of line items displayed. The last view remains. No scroll bar is available to see previous entries.
•CSCsi84648 - Reset button does not reset Log Levels, but acts as Apply button
Summary: From Log Files, if you change the Log Level for CCS process to DEBUG (the default is INFO) and then click Reset, the field is not reset but applied and the Apply button is grayed out.
•CSCsi95884 - If the SFTP port number is changed during CTMS software upgrade, the wizard does not retain the changes
Summary: If the SFTP port number is changed during CTMS software upgrade, the wizard does not retain the changes.
•CSCsj02267: CTMS host name change not allowed
Summary: Users cannot change host name from CLI. Web UI has no option to change hostname.
•CSCsj05237 - No status shown if the user relaunches the web page during software upgrade
Summary: If a user closes the web pages after initiating the upgrade process (the auto switch version), and later re-launches the same upgrade page to check the progress, there is no status given; instead, it shows "Preparing upgrade patch," which was already done.
•CSCsj15373 - GUI "hangs" after being idle
Summary: After idle time, GUI hangs; user cannot access anything or log out. When this happens, user must close web browser, open a new browser, and log in again.
•CSCsj24360: Log files shown on the GUI does not match downloaded number of log files
Summary: From Log Files, if you select "Download All" and the click "Okay," and then open the zipped file for the log files, the number of log files listed on the GUI does not match the number of files in the zipped file.
•CSCsj31510 - Schedulable segments value blank out when Reset button is clicked
Summary: In System Configuration, under System Settings, on the Resource Management window, when user changes the AdHoc segment value and clicks the Reset button, Schedulable segments value blanks out and the Apply and Reset buttons are grayed out.
•CSCsj35537: Cannot open files directly listed in Log Files when "All" is selected
Summary: From Log Files, if you click "License,properties," the system opens a new web browser without any contents. There is no option to Open, Save or Cancel.
•CSCsj44260 - Software upgrade/downgrade wording needs to be changed
Summary: Customers can select to upgrade or downgrade versions of CTMS software. When users are switching to a lower version of the software, the message should say "downgrade" instead of "upgrade."
•CSCsj48010 - Very long description in template shows up as "Null."
Summary: From AdHoc Meeting, if you select Templates and then add a long meeting description, when you launch an Ad Hoc meeting using that template, the Meeting Description shows up as "null."
•CSCsj87499 - Dual image on single
Summary: When CTMS media received an IDR, it will have its destination cache invalidated. CTMS has a problem in RTP processing logic. It may result in IDR packet from new segment (active speaker) dropped, and send streams from another segment wrongly to the destination.
•CSCsj90876 - Media destination cache optimization to reduce RTP processing window
Summary: One of the major overheads in media process is the time spent on EPO lookup for each packet in user space. There was transmission destination cache implemented. The cache is invalidated for each RTP processing window.
The enhancement is to cache transmission destination for all segments for all end points including both video and audio. The performance of media is expected to be significantly improved further.
•CSCsj92140 - Incorrect audio packet handling causes switch to sometimes be unresponsive
Summary: Under rare condition, when MediaProcessor may buffer more than one audio packet in a UDP channel, only the first packet has its confidence level updated into rank table. All other packets buffered do not get the chance to update their confidence level into rank table. This error can cause switching to be unresponsive when two segments from same endpoint compete.
•CSCsj92146 - Media statistics enhancement
Summary: Media need enhance statistics for troubleshooting. The following statistics need to be added.
–Mean jitter standard deviation
–Mean video frame duration standard deviation
–Max ssrc switch count per 4 seconds
–Calculate video jitter based on mux version with either first packet of a video frame or last packet of video frame.
–Total packets received and transmitted
•CSCsj92637 - Unable to add or modify DNS entries via CTMS web page
Summary: The CTMS web page does not allow users to add or modify the DNS entries. Only IP, Subnet Mask and Default Gateway values can be modified.
•CSCsj92688 - Inconsistent switch and IDR packet lost
Summary: When a top active speaker is detected and IDR is received by media, Media use source SSRC derives segment information to calculate index to transmission destination cache. The cache gets updated when the media layer goes through the EPO table to find a list of destinations to transmit a packet. Whenever a destination is found, it gets added to destination cache based on index calculated from rtp packet ssrc. Since media manipulate ssrc in the same packet for each iteration finding destination, the source ssrc used for cache index calculation keeps changing. It may result in the wrong cache index if the ssrc is the same before or after manipulation.
•CSCsk43793 - Web should not restart CTMS processes when updating resources
Summary: When some parameters like resources are updated from web, web should not restart CTMS processes; it should delete all active conferences and then reset the parameters.
Closed and Resolved Caveats from CTMS Release 1.0.2(250)
•CSCsj31519 - Switching policy cannot be configured after upgrade from Cisco TelePresence Manager (CTS-Man) Release 1.1 to CTS-Man Release 1.2.
Summary: After completing upgrade from CTS-Man 1.1 to CTS-Man 1.2, the MCU field value is "N/A" and the field from which a user can select a new policy is disabled.
•CSCsj51298 - Calls cannot be cancelled if the dialed-out number is preceded with "0."
•CSCsj35537: Cannot open Log files directly when "All" is selected.
Summary: When you click "Log Files" in CTMS Administration Software, and then select "Licence Properties," a new web browser window opens with no content.
•CSCsj38998: Log files contain extraneous files.
Summary: Log files contain extra files that are not useful for debugging
Open Caveats from CTMS Release 1.0
•CSCsi44352: Time zone is not configurable during installation.
Summary: CTMS server is defaulting GMT and not offering an option to select the right time zone during installation or through CLI post install.
Status: Information Required.
Closed and Resolved Caveats from CTMS Release 1.0
•CSCsh81490: If you enter data and then move to another tab without selecting "Apply," no warning message is displayed.
Summary: In System Settings, if you enter data in Access Management and then select another tab (QoS tab, for example), no warning message is displayed, telling you that the data you entered will be lost.
•CSCsi26863: A call exceeding maximum streams should return a "fast busy."
Summary: A call exceeding maximum streams should return a "fast busy." Currently, the caller is dropped without any indication. Maximum streams is configured in the CTMS Administration software. If it is set to 20, a caller attempting to allocated the 21st stream should be sent a busy signal.
•CSCsi45541: In the CTMS Administration software, there is an inconsistent use of terms: rooms versus segment.
Summary: In CTMS Administration software, parameters under System Settings and Resource Management use the term "segments." Default Settings under Meeting Management uses the term "rooms." Default settings also includes site/segment switching parameter. Recommendation: use "segments" consistently throughout.
•CSCsi46414: Cannot delete template.
Summary: After a template is created, it cannot be deleted.
•CSCsi48875: CTMS should reject audio calls if it receives an audio only SDP.
Summary: If CTMS receives an audio only SDP, it should reject this call immediately. Today, it proceeds as normal: it opens its media ports and waits for AppMux packet. When the AppMux packet doesn't come, it does a media timeout and raises a warning alarm.
•CSCsi48916: Cannot delete user.
Summary: After a user is created, it cannot be deleted.
•CSCsi52075: The Ad hoc Meeting Status page displays inconsistent state.
Summary: After creating an ad hoc conference with three attendees, the conference was cancelled from the Ad Hoc meeting status page. The status displays that the meeting was terminated by end user, then calling state, then media timeout occurred.
•CSCsi52572: CTMS CLI "modifyconf" command does not work for Static Meetings.
Summary: Policy is not changed when using "modifyconf" for Static meetings.
•CSCsi53840: When a CTS-1000 exits a conference, another CTS-1000 active speaker may be displayed briefly.
Summary: There is a corner case where if a specific CTS-1000 is the active speaker and a different CTS-1000 leaves the conference, the first CTS-1000 can show up on 2 displays for a few seconds.
•CSCsi54335: The Static Conference dialed number changed after hold/resume.
Summary: The phone user interface displayed a different dialed number after a static conference call was put on hold and then resumed.
•CSCsi55871: Media Processor log level change above INFO causes jitter.
Summary: The Media Processor log level default value is INFO; this is different from all other processes. If it is changed above INFO that Jitter could/will result.
•CSCsi58667: Two video picture overlaps—one actual and one transparent.
Summary: Occasionally during conferences, two video pictures overlap: one of the active speaker, and a transparent image of another speaker. This artifact clears up when someone else switches in the segment.
•CSCsi69494: After Hold/Resume with hosted meeting, participants can join.
Summary: If the host does not join the conference, pressing hold/resume on the two other CTS-1000 devices causes them to join the hosted meeting.
•CSCsi67495: When first conference participant is put on hold, video does not resume when second participant joins conference.
Description: When the first participant joins a meeting, they are put on hold by the CTMS over a SIP trunk. This creates an icon on the screen (hourglass) that alerts the user that they are the first participant. When a second participant joins, they are resumed. On the resume, the call information is being sent by Cisco Unified Communications Manager with a video port set to zero. This causes no video is sent to the end point. To recover, they must drop from the meeting and re-enter.
•CSCsi70080: Timeout only displays voice mail dialed number instead of going to voice mail.
Summary: After starting an ad hoc meeting, created a second ad hoc meeting with the same dialed number; only displays voice mail dialed number instead of going to voice mail.
•CSCsi71121: No indication given when switching versions.
Summary: When switching versions, the web page refreshed back to the platform login page. It should give the status of shutting down until the link is out.
•CSCsi71444: No hourglass icon on second try to join hosted meeting.
Summary: On first call into a hosted meeting from non hosted end points, an hourglass icon is displayed. On second call into the hosted meeting, no icon is displayed.
