Outbound calls disconnecting after 180 seconds

We are having a problem with outbound calls in that the calls are connecting OK, but we (the caller) get a busy tone after 180 seconds and the call disconnects. I notice that the ringing timeouts on the FXO ports is set to 180 seconds, so i think this is the cause of the problem.

However, the calls ARE connecting to the outside, so it should not be timing out. I guess that the Ports are not realsing that the call has been answered and treating the call as though its still ringing

Any help or pointers would be great. The FXO Port is configured as follows

voice-port 0/1/0
supervisory disconnect dualtone pre-connect
supervisory answer dualtone
cptone GB
connection plar opx 305
impedance complex2
description Configured by CCA 4 FXO-0/1/0-Custom
caller-id alerting dsp-pre-allocate

Many thanks

Paul

Do you resolved this Issue ¿?

I have a similar problem, we have 2 lines in FXO for in and outside calls, and 1 Voip service for international calls, the calls from in and outside from de Voip service works fine, but the FXO in outbound calls cut the calls after 2 minutes aproxim.

Do you resolved the problem ¿?, please post your opinion.
