Cisco 8845 Call Failure Over SIP Trunk When Video Enable

Hi All,

We are facing an issue. We have two SIP trunks, one from local provider another from international (only for international calls). And we have two different types of the phone registered with CME, 7945 and 8845. SIP Trunk also terminated on the same CME. The international calls are failing when the video is enabled on 8845 (getting reorder tone, cause code=3). The call is successful when the video is disabled. 7945 has no issues for local or international calls. 

I have used the following to disable the video codecs in the SIP invite. The call is going through but only one-way audio. 

 

voice class sip-profiles 1
request ANY sdp-header Video-Attribute remove
request ANY sdp-header Video-Media modify "m=video(.*)" ""
request ANY sdp-header Video-Bandwidth-Info remove

 

Any help is greatly appreciated.

 

Thank you

Re: Cisco 8845 Call Failure Over SIP Trunk When Video Enable

There are two solutions that we were able to use that resolve the same exact problem, either one worked for us. We stayed with modifying the dial-peer.

1. We had issues on firmware 12-1-1, we could downgrade to fix the issue.

2. We added "voice-class sip audio forced" to the outgoing dial-peer to fix the issue.

Use below Video Suppression Guide to disable video only

Enter one of the following commands:
• In the dial-peer configuration mode
voice-class sip audio forced
• In the global VoIP SIP configuration mode
audio forced
