I've found that the Asterisk SIP implementation does not work well with Polycom video. You need to use the video branch, and add code to gain support for fmtp SIP messages in order to get the Asterisk SIP channel to recognize video properly. There was a hack that was posted some time ago that I'm using to get this to work in my own development code. An associated comment indicated that some thought needed to be applied to make the hack something that could be checked into the repository.
So, my specific request is that FMTP messages get added to chan_sip.c as well as add in some of the changes from the video branch to support Polycom video.

Ensure videosupport=yes. Then see what works and doesn't. Video voicemail should be OK but may not be sync'ed very well. PolyCom to PolyCom should work OK. PolyCom to Grandstream may work, depending on who initiates the call. IVR usage should be irrelevant, but Queuing might be an issue. Also it is vital that all phones are upgraded to latest firmware. Then come back and ask for something more specific to be fixed. johnny_xing wrote: Hi, I understand there are some problems while integrating Polycom video phone with asterisk and passing through is fine for Grandstream. I would like to pay for any patch / customization service to asterisk so that I could make video calls between Polycom VVX 1500, video recordings, voicemail, and IVR. Please contact me if anybody has a suitable solution.
