Polycom DMA End-Point to VCSc End-Point; One-Way Video and Then Disconnects
I have a new VCSc with an MX200 dialing an EX60 registered to Polycom DMA via a SIP trunk (both end-points are SIP). When dialing from MX200/VCSc to EX60/DMA, calls are connected and remain connected. However, when dialing from EX60/Polycom DMA to VCSc/MX200, call connects, but then disconnects (on the MX200) after 30 seconds. Call history on the MX200 shows local disconnected for the reason. The EX60 only shows that the video portion has stopped (although I can no longer hear any audio).
Firstly, your question would be better placed in the TelePresence section of the forums where these devices are more actively discussed than in the Video Over IP section you've posted in - I'd suggest you move your discussion.
But to start to address your problem - the first place to look would be on the firewalls - check to see if they're blocking any of the SIP traffic. Also disable any SIP packet inspection - the packet inspection has been known in the past (especially with H.323 calls) to cause issues.

Thanks Wayne for the input. I should have included the fact that this was all internal infrastructure. The problem ended up being rule ordering on the Polycom DMA, which still doesn't sit well with me, but it works :)
Thanks for the input, and agree on the TelePresence section would have been better placement. I'm sure I'll have other opportunities :)

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
