Is there a trick to getting VAD working on a video conference when using G.711 audio? I'm trying to see if this product would work for us in my company for a simple video conference bridge (As a feature server, not the core call control.) I'm able to get DTMF switching working, but when I try to enable VAD it doesn't work as I would expect. (Basically, it never switches unless a video caller hangs up.) Speex is not an option for us because of the other equipment and software involved, unless I misunderstand something about Speex. (My understanding is that it is a codec that would displace the use of G.711.)
I've tried many variations of the dial plan switches to no avail. The current dial plan I am using is:
I posted the wrong version of the dial plan, so I know that the X is wrong; should be an S. I did my tests with switches "Szo", along with several other variations.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Hi all!
Is there a trick to getting VAD working on a video conference when using G.711 audio? I'm trying to see if this product would work for us in my company for a simple video conference bridge (As a feature server, not the core call control.) I'm able to get DTMF switching working, but when I try to enable VAD it doesn't work as I would expect. (Basically, it never switches unless a video caller hangs up.)

(My understanding is that it is a codec that would displace the use of G.711.)
I've tried many variations of the dial plan switches to no avail. The current dial plan I am using is:
exten => _740X,1,Answer()
exten => _740X,n,Wait(1)
exten => _740X,n,Konference(testconf,Xzo,video_start_timeout=500,video_stop_timeout=500)
exten => _740X,n,Hangup()
Callers are handed off from the call control servers to this box using a SIP trunk.
Any tips? Like I said, the thing works just fine with DTMF, so I think all of the basics should be in place to allow VAD as well.
Thanks in advance!

Won't work also. Has wait for new versions but in 2.0 video not exist at all ((
Using gsm/h263 codecs for conference.
