Calls from PSTN to Unity Voice Mail drop after 45 - 50 seconds

[oscar.perez]

I have a MGCP gateway with a T1 PRI, when an outside user calls and the Voice Mail kicks in, the call is dropped after 45 to 50 seconds. If you dial from an inside extension to Unity it works fine.

CCM: 4.1(3)

Unity: 4.2(1)

Any ideas?

Add this command to your MGCP configuration:

"no mgcp timer receive-rtcp"
