[Asterisk-video] Video with Polycom VVX1500

[Gallmeier, Jonathan]

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.

First off, try Asterisk 1.6.0 and only allow H.264 codec and whatever
audio codec you want. 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.

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.

 

Thanks & Best Regards,

 

Johnny Xing
