VCS to CUCM - No video after upgrade to CUCM 9.1

Hello all.

I hope one of you can help me.


I am running VCS X7.1

The CUCM was running 8.5 and I had video calls working from VCS to Jabber for Windows.

Then we upgraded CUCM to 9.1.

Now, I can only answer the call on my 7945 (no video phone) and get voice OK. but If I try to answer with my Jabber for windows the call fails and no audio or wideo.


I have followed this document http://www.cisco.com/en/US/docs/telepresence/infrastructure/vcs/config_guide/Cisco_VCS_Cisco_Unified_Communications_Manager_Deployment_Guide_CUCM_8_9_and_X7-2.pdf


But still does not work.


anyone else hav had this problem?

I just installed VCS X7.2 and CUCM 9.1.2 using the doc you referenced and I am able to do video from outside callers (via VCS-E) to all video endpoints/devices registerd to CUCM (9971, Jabber, MX300, and MCU). So, the products will work together.


I'd suggest taking a look at your region settings to ensure you aren't blocking video somehow. I assume that if you followed the guide correctly that you have ensured that SIP profiles, trunk security profiles, SIP trunks, normalization scripts, etc. are all configured correctly. I know that 9.1 has a pre-canned normalization script for VCS and a specific SIP profile.

Thank you for answering.


I did check the region and location to make sure that video is not beeing blocked.


The stragne thing is that it used to work when I was runing CUCM 8.5.

After the upgrade it stopped working. Then I went thorugh the document refered to and changed the settings that was missmatching from the earlier CUCM version.


but still no video, not even able to answer the call on jabber.

OK. I would do the following:


1. Check the VCS search history to ensure that the search request is found (which I am sure it is)


2. If the call connected (even if media failed) then it may be worthwhile looking at the call history on VCS, find your call and drill in to see if you can find anything of interest.


3. On CUCM, you can use RTMT Session Trace to get information on the SIP session set up. It is a pretty handy tool that reads the call traces and renders them in an easy-to-navigate ladder diagram. You will want to look at the SIP messages that include the SDP information. It should help identify media negotiation issues. You can also do a SIP call trace on CUCM (if you prefer).


I did a write up on the RTMT Session Trace tool here:

Hi,

       I was wondering if you found a resolution to your issue?. We are experiencing a very similar issue and it would be interesting to know what others have seen. We have done many traces and drilled into the calls on VCS to no avail.

 

          regards,

                       Zack
