I had this problem a few month ago and cleared with no resolution on 2 separate bridges using the same configuration. I am using a ADTRAN ISU 512 to make ISDN calls and connecting via MPI to the bridge. I am able to call and negotiate and all is well for up to 2 minutes but then recieve video intermittenly locks up. It eventually clears but then locks up again. Audio seems to continue working the whole time with small interuptions. I'm at my wits end on this. At&t who is the ISDN provider indicates there tests come back good. Im sure its a timing issue but even my support contract folks seem at a loss.
