Caveats
This section contains open and resolved software caveats for this release of Cisco CallManager. Caveats describe unexpected behavior or defects in Cisco CallManager software or related hardware.
Open Caveats for Cisco CallManager Release 2.3(1b) and 2.3(2)
This section describes possibly unexpected behavior by Cisco CallManager Release 2.3(1b) and 2.3(2). Unless otherwise noted, these caveats apply to all Cisco CallManager 2.3 releases up to and including Cisco CallManager Release 2.3(1b) and 2.3(2).
•
Cisco IP phones (Selsius IP phones) calling busy offnet telephone numbers via an AS5300 gateway hear three bursts of ring and then they get the expected busy tone.
Traces indicate the AS5300 is passing a busy indicator to Cisco CallManager, but it is ignored for a period before the Cisco CallManager sends the busy tone to the calling party.
•
Symptoms:
1) After connecting the line between 9998 and 7388, the line can be used for 90 seconds. Then the line is disconnected. The display of 9998 phone shows Resetting 33 message, and 9998 phone is reset. No one goes on-hook on any phone. But the message shows up at 9998 phone, and 9998 phone is reset (copyright message).
2) After connecting the line between 9998 and 7388, the line can be used for 80 seconds. Then the line is disconnected. The display of 9998 phone shows Resetting 32 message, and 9998 phone is reset. No one goes on-hook on any phone. But the message shows up at 9998 phone, and 9998 phone is reset (copyright message).
Workaround:
Problem traced to bad datecode of DSP on IP board in phone. Current stock of parts was inspected, and no bad date codes were found. Defective phones typically show the above symptoms when making a G.723 call. Possible workaround is to use G.711 or replace the phone.
•
Cannot change the calling party selection for H323 devices. Experiencing call routing problem to the voice mail since the calling number is not redirected by Cisco CallManager. So caller (ext. 1111) call to (ext. 2222) goes to its own (1111) voice mail, since the calling number does not get redirected by Cisco CallManager.
Workaround: Use a Digital Trunk 24-port (DT-24) PRI or an 8-port Analogue Trunk (AT8).
•
The DT-24 T1 Port parameter field "Call Direction" does not appear to work. Call Direction specifies the direction of calls passing through this port. Allowed settings are:
•
•
•
Workaround: Use a Digital Trunk 24-port (DT-24) PRI or an 8-port Analogue Trunk (AT8).
•
Call forwarding for directory numbers assigned to Cisco IP phones that are removed from the network may experience varied results.
Workaround: Make sure that an entry exists for forward on no answer and forward on busy. That way, if the phone is not registered and Cisco CallManager treats it as busy, it will forward calls anyway.
•
Scenario:
PSTN --- FXO (3640) --- Ethernet --- Cisco CallManager --- Cisco IP phone (x7330)
The Cisco IP phone has two extensions, x7330 and x8611 7330. On busy, 7330 forwards to 8611 7330. Cisco CallManager has Global call waiting disabled to make forwarding work. Cisco CallManager version used is 2.3(1a).
When a call is received from PSTN to the 3640, it gets pushed (Connection Plar) to 7330. Another call comes in, the first phone is placed on hold, and the second call (now on line 8611 7330) is picked up. However, when the second call is over, the user goes back to the first call on hold, presses the line button to retrieve the call, and the call automatically disconnects. Sometimes it disconnects instantly; sometimes it takes about two seconds.
Workaround: Edit the scm.ini file and change holdtype=1 to holdtype=0.
•
Symptom: Cisco CallManager takes up more memory room after heavy use than when first installed.
Condition: In our tests, calls in excess of one million increased Cisco CallManager by 70 MB.
Workaround: There is no workaround, but system impact should be minimal. This problem will be addressed in a future release.
•
When a call is placed to a voice gateway, the caller first hears internal dialtone. The caller then dials the access code for an off-net call. External dialtone is heard, and the call is made and then cleared normally.
When the caller uses the redial facility, he first hears internal dial-tone. When the caller presses the Redial key, he hears external dial-tone for five seconds or so before the connection is made. This dialtone is played out for too long and should be replaced with silence.
Workaround: There is no current workaround. The issue appears to be due to the slow connect through the H.323 Gateway. The issue is still under investigation.
•
Scenario:
1) Telephone A makes a call to B using 4100 number.
2) Telephone B gets the call and tries to transfer the call using the transfer button.
3) Then B pushes a call park button.
4) Next B pushes another line button (for ext. 4100).
5) If B pushes the HOLD button, there is no beep sound.
For this test, first use one second for 'ToneOnHoldTime'. The same problem happens if using two seconds. But this problem cannot be reproduced if five seconds is used for 'ToneOnHoldTime'.
Workaround: Increase the beep tone to 5 second intervals or more.
•
If you enable the service parameter "Block Offnet to Offnet Transfer" and make a blind transfer with Cisco Unity Connection, the Q.931 SETUP message which CUCM sends to the PSTN gateway for an outbound PRI call still reaches the gateway. This transfer results in a dropped call.
Resolved Caveats for Cisco CallManager Release 2.3(1b) and 2.3(2)
This section describes possibly unexpected behavior by Cisco CallManager Release 2.3(1b) and 2.3(2). Unless otherwise noted, these caveats apply to all Cisco CallManager 2.3 releases up to and including Cisco CallManager Release 2.3(1b) and 2.3(2).
All the caveats listed in this section are resolved as of Cisco CallManager Release 2.3(1b) and 2.3(2).
•
This condition is caused by a POTS phone user, attached to an analog trunk, initiating and aborting a flash hook transfer during an outgoing analog trunk call.
The trunk port is cleared after the Cisco Access Analog Trunk Gateway is reset.
•
Some IP Phones were experiencing random loss of two-way audio. A new phone load has fixed this problem.
•
This problem only occurs if **112 self-test is run with trace enabled. This is only used by manufacturing to test the phones, and trace is not enabled by manufacturing. This problem should not be encountered by customers.
•
This problem appears to be unique to the configuration at one site. We have not seen this problem at other customer sites.
•
This problem was found at one site and is a rare occurrence based on close timing of events. A held call is retrieved at the same instant as the arrival of a new call on the same line. If this problem occurs, no new calls are allowed on that line. The workaround is to reset the phones that have that line appearance, to clear the line for new calls.
•
The UnicastActiveConfParticipants and UnicastConferenceActive counters are incremented when an attempt is made to connect to a Unicast Conference and the attempt is rejected due to incompatible capabilities, media connection errors, or adding participants to a Meet-Me conference too quickly. This causes the conference resources to be consumed over a period of time and not released.
Visible symptoms are: 1) The counters do not return to zero when all conferences are terminated. 2) Fewer than the configured number of conferences can be created. 3) New conferences cannot be created at all. 4) Fewer than the maximum number of allowed conference participants can be added to a conference.
Workaround: Cisco CallManager must be reset in order to free conference resources that have been consumed. There is no workaround other than to ensure that those attempting to join conferences are using G.711 codecs, and that conference participants do not join Meet-Me conferences too quickly. This problem is resolved in Cisco CallManager Release 2.02(27).
•
When placing many calls using the H.323 protocol, Cisco CallManager would go to exception. This current entry mentions that it was involving Conference Bridge, but in fact Conference Bridge was not the root of the problem. Any H.323 call could cause an exception, especially when made in rapid succession. Unfortunately there is no workaround other than not to make H.323 type calls. There is a new H.245 DLL for Cisco CallManager Release 2.2(27.3).
•
The caller ID field in ISDN messages will no longer send a "X" in the Calling Party IE field. Also, it is now possible to enable Overlap Receiving on the User Side protocol of PRI-ISDN protocol. This is done in the scm.ini file by setting OverlapReceivingForPriFlag=1.
•
When placing calls in Japan, if the called party number field "Type of Number == unknown," then the "Number Plan Identification field must also == unknown". This is controllable in the scm.ini file by setting NumberingPlanInfo=1. This is not the current default setting.
Open Caveats for Cisco CallManager Release 2.2
This section describes possibly unexpected behavior by Cisco CallManager Release 2.2. Unless otherwise noted, these caveats apply to all Cisco CallManager 2.2 releases up to and including Cisco CallManager Release 2.2(27).
•
Existing route filter values cannot be seen in the form view of the Route Filter Configure dialog box.
•
After a client places a DirectoryServices Call via the web browser, use of the browser's Back button can cause the call to be placed again.
Workaround: After the directory services call is placed, the ASP page should be refreshed so that the browser's Back button will not place/redial the previously placed call.
•
A session disconnect problem happened with 5513 (ext) phone. A call between two phones was connected. Five minutes later the line was disconnected suddenly. At that time the content of the display changed from phone number to date. The time and copyright message did not display.
Workaround: Refer to caveat CSCdm52724.
•
A call originated from H.323 is not able to hear ring-back tone during transfer from one ethernet phone to another ethernet phone.
Workaround: Use a Digital Trunk 24-port (DT-24) PRI or an 8-port Analogue Trunk (AT8).
Resolved Caveats for Cisco CallManager Release 2.2
This section describes possibly unexpected behavior by Cisco CallManager Release 2.2. Unless otherwise noted, these caveats apply to all Cisco CallManager 2.2 releases up to and including Cisco CallManager Release 2.2(27).
All the caveats listed in this section were resolved in, or prior to, Cisco CallManager Release 2.3(1b) or 2.3(2).
•
Cisco CallManager crashes periodically with the following error:
Dr. Watson error message:scm.exe Exception: access violation (0xc0000005), Address 0x78001230•
When configuring route patterns assigned to a specific Analog Trunk Gateway Port, the outbound calls fail with the error:
Outbound call attempted on Vega but no Outbound or Bothways ports availableThe issue is resolved by configuring all ports for the specific route pattern.
•
When trying to access the device pool with the "-", Cisco CallManager displays the standard USER INPUT VALIDATION ERROR because the device pool name is invalid. A valid name can contain only "-" and spaces.
•
Symptom: A call is placed between two IP phones, and after a time the audio stops and one phone plays the reorder tone. The second phone continues to display the call information. When the second phone goes on hook, the display shows the copyright message and then date/time when it reconnects to the CallManager.
Workaround: Install the P002H202 software load on the 30 VIP and 12 SP+ phones.
•
Audio Playout of voice message greeting.wav file through MTP does not work correctly.
•
Symptom: Users encounter the following error when trying to install the Selsius TSP on a machine:
An error occurred during the move data process: -119Component: Shared DLLsFile Group: Self Registerd System32 DLLsFile: C:\WINNTSystem32SelsiusTSP.tspThe progress bar is at 12%.
Workaround: All the machines that were failing did not have MSVCP50.DLL in the System32 directory. Once this file is copied to that location, the install works.
•
Cisco IP phones (Selsius IP phones) may not restart properly (re-register with the CallManager) after the CallManager process is stopped and started. The phones are stuck at the Copyright message and the lights are off.
The only known situation where this happens is when the phones are not using DHCP (that is, the IP address and related information is manually entered) and the phones are on the 192.4.250.X subnet with a 255.255.255.0 mask
