RPD in H.323 mode

[rakeshprasad13]

Hi All,

I am facing a problem with RPD in H.323 mode ( both standalone as well as when registered to Cisco VCS).

In the H.323 call the audio is through but the call is not escalating to Video. 

Any thougts/ ideas/ Direction will be highly appriciable......

Thanks & Regards

Adding some more details :-

In the failure scenario during this testing, the OLC packet for GenericVideoCapability being initiated from the Endpoint after MSD and TCS exchange is not seen:

The traces in the RPDLogCollector show many error messages, some like closure of the ‘VideoRTCPSession’ with some error codes:

I'm not sure I understand you correctly.  

I think you said that the MSD and TCS are *not* seen?  If this is the case, then I am suprised that you even got audio.

Or you might have said that after the MSD and TCS were seen, the OLC for GenericVideoCapability was not seen.  One reason this might occur would be if there were no matching video capabililties between the calling and called parties.
