I was hoping someone could help explain this?
I have made several test calls over ISDN to a Polycom HDX from our Cisco infrastructure. From an Edge95 MXP or C20 both SIP and H323 calls negotiate okay using H264 and audio/video is present. If I use Movi/Jabber the call predominantly uses H263 and I do not get video back from the far end. Out of 10 test calls 8 failed and used H263 but strangely two succeeded because they negotiated H264.
Why would this be please? I can look at disabling H263 and take that path but that could lead to unforseen interop problems down the road. I would prefer to determine why Jabber is favoring H263 when the Edge and C20 clearly aren't??
Any suggestions would be appreciated please
