<div>You mean the calls over a pri? drop after a period of time. We had a very similar problem with a cleint using v4.1. The issue was the site had not yet come up on the dedicated circuit and was operating over a vpn tunnel. They used checkpoint FW end to end was blocking h.245 signalling even though the FW engineers swore it was an open tunnel. The phones registered to call manager normally, interoffice dialing over wan worked fine. Calls from that location out the local pri dropped a short time after making it. Also when users dialed in to the local gw there was one way audio. As we worked with the engineers on the checkpoint firewall the one way audio dissapeared but they never quite got the call dropping fixed until we go the mpls up and disconnected the vpn tunnel.</div>

Recently I've started to receive complains that calls that go over some of the trunks that we have with other locations fail after exactly 5 min and 18 sec. Can anyone try to help me how to determine the reason for the call drops.
