I've had a problem recently with unity 4.04 ports stop working. When I look in call manager, they are registered and "appear" just fine, however they do not answer and have been causing problems with busy signals etc. I reset them in Unity with no avail. The only way to clear them is by going to the hunt list in call manager and going to each port and individually resetting it. They may then work for several hours or up to a few days, but then intermittently stop working again. This is unity 4.04 with TSP 8.1(3)
Prior to upgrading to Unity 4.0(5), we used to have this problem intermittently, but specific to one port hanging. Unity 4.0(5) fixed this for us and has not reoccurred since. We are running 4.2(1) and I have not seen this error on this very stable version, in my opinion.

Now this port problem. We are using the TSP 8.13 which we upgraded when we did the CM upgrade... I have no idea what could be causing... I've rebooted it and keep resetting the ports which work for a while then stop...
