Have a polycom vsx 8000 between a 2800 (C2800NM-ADVSECURITYK9-M), Version 12.4(12a) series router and a 1811 router. 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.
