Unity Port Issue

Revs: CallManager - 3.1.1 / TSP 3.0.0.7 / Unity 2.4.6.135<br>G.729 prompts / NT 2000 / Exchange 5.5<br><br>Since upgrading a client's Unity to current release / patch<br>levels, they have experienced occasional trouble with the<br>first voice mail port ringing until Call Manager acts on<br>this issue like a NA, thus being forwarded to the second<br>voice mail port.<br><br>The second port will show that it is playing the prompt<br>that should be played, but the message is never played.<br><br>A Unity reboot clears the issue - and the issue has been<br>found to be intermittant (argh).<br><br>No issues are found in the logs.<br><br>The issue began when Unity and the TSP was upgraded from<br>stock CD versions.<br><br>We have opened a TAC case, though we are waiting for call<br>back (priority 3).<br><br>We would like to get ideas of how to troubleshoot this issue<br>further than the following:<br><br>* Directly dial the "blocked" first voice mail port.<br>* Directly dial the "blocked" second voice mail port.<br>* Take the first port out of service, and see if the second<br>port begins to function correctly.<br>* Reset the first port, and see if the first port begins to<br>function correctly.<br><br>What logs should we be running to capture this issue?<br><br>Could it be a call collision causing this issue?<br><br>--- Thanks ---<br><br>

Re: Unity Port Issue

Your best bet is to start a CCM trace. Once you see that the port has gone dead you can stop the traces. The TAC engineer should be able to understand from the traces what the problem is. Basically we are going to be looking to see what happened during the last good phone call to the Unity.

Re: Unity Port Issue

Just kind of a crazy question, but you don't happen to have two nics in your unity box do you? I saw this issue once where the port mon. says that the unity is playing a greeting but you won't hear it.
