Have a polycom vsx 8000 behind a pix firewall running 7.2 the quality is fine,but after 60 minutes (exactly) the call will drop. We are using dynamic ports on the polycom. Does anyone have an idea on what we can do to extend the call length?
Thanks for your help.
There was a discussion of this issue on the VTCTALK form at http://www.vtctalk.com//showthread.php?t=11450.
"timeout value in the PIX firewall that was causing the calls to drop. It was the H225 timeout"
check it out to see if it relates to your symptom.
