when the other party terminates the call, my IP phones do not hang up. I can see the traffic stop by looking at the output of a tcpdump -nn host 192.168.1.99. I can see the instant I hang up the mobile phone. It stops alternating ports. I'm assuming I'm not still connected with my carrier, which is important to me. This seems to be only in a new installation. Had the same box in a different location, and I don't think I had the same issue. Have experienced this talking to a mobile phone and the PaloSanto 877 number, on two different IP phones. Is there some hangup setting I can look at?

This problem is resolved. It was a router issue. Changed router to a known good brand and configuration and things work marvelously.
