I am using a Polycom VSX 8000 SW version 2.0.1
Our bridging service (Level 3, formerly Global Crossings) calls our ISDN site to connect us to a video-conference. On the bridge side the Carrier is Quest, the bridge was Codian, and the ISDN protocols were limited to H.261 or H.263 (although it also failed with no limit on protocols). If the call has an IP-based site then we get connected after the call from the bridge. However, we only stay connected for maybe 5 seconds. after the '5 seconds' the screen freezes and my Polycom VSX8000 reboots.
The only way we were able to get the call to work was to have the ISDN sites called on an Accord bridge while the IP sites call the codian bridge. Then Level 3 bridges the bridges. This does work, but it limits the display options.
Any comments, ideas, or donuts?
I appreciate any help I can find....
I believe you may have looked in the wrong place for the VSX software version as the versions range from original of 7.x to 188.8.131.52.
From your problem statement I may assume the below is a possible cause and an upgrade to the VSX will possible resolve the issue.

The Codian MCU is not able to hand w480p (848 x 480) resolution
