I think I found the problem. Well, the router was running IOS 12.4(3)g, and I upgraded to 12.4(8)c as per my company standard and found that I have gone the whole day without a hung fxo port. I will continue to monitor but I'm convinced that upgrading the IOS was the trick.

<p>I configured the 'supervisory disconnect dualtone mid-call' command under the voice port. I shut no shut the voiceport and waited to see what happened. It didn't fix the issue. A couple hours later there was another hung voiceport.

<p>I have not had this problem before with h323. If it were MGCP I could see the logic, but this is a first for me.<br><br> </p></div>
