We are connecting two QSIG voice switches through a compressed VoIP trunk (E1, except channel 15 and 18) using two cisco 2620 routers with IOS 12.2(8)T4, and NM-HDV-1E1-30.
Switch1 Router1 Router2 Switch2 (network) (user) (network) (user) With this setup we can connect any call originating from switch2 to switch1 direction. But a call originating from switch1 does not connect the *voice path* after several successful calls when under moderate/heavy load. (ie: the call is connected but voice is not heard by either party) Shutting down the voice port and bringing it up again could resolve this temporarily. But after several calls, same problem occurs. Calls from switch2 to switch1 continue to connect properly.

I have not included the dial-peers as they seems to work properly. Any ideas what the problem might be? Thanks!
