During course of call the video hangs after 1 min. If I disconnect the call the image remains in the screen and force us to restart the system to get our image on the screen. Kindly help us.
We're going to need a bit more info.
Which Polycom System?
What Software Version (See System Info)?
What type of conjnection, ISDN, IP, SIP?
Do you have another VC system INSIDE your network & does that work OK?
Does it hang up to ALL locations after 1min? (Test sites are here http://support.polycom.com/PolycomService/support/us/support/documentation/video_test_numbers.html)
