Had a call center agent call in a report on a dropped call.. trying to determine what happened to cause it to drop.<br><br>Since this has IPCC involved, I have less of a clue as to whats going on than normal. The first messages that I see in the trace file when the call dropped are:
<br>03/28/2007 15:45:14.823 CCM|StationD(226): StationCtiD - CtiLineCallDisconnectReq LH=5<br>03/28/2007 15:45:14.823 CCM|StationD(226): StationCtiD - CtiLineCallDisconnectReq LH=5<br>03/28/2007 15:45:14.823 CCM|StationD(226): StationCtiD - StationOnHook
<br>03/28/2007 15:45:14.823 CCM|StationD(226): StationCtiD - StationOnHook<br>This seems to tell me that either callmanager or ipcc is tearing down the call rather than the agent bumping a button or something... or perhaps the user is doing it via CAD somehow and doesnt know it. I don't see any reset messages in callmanager for that phone to have lost connectivity.
<br><br>Then some lines down, <br clear="all">03/28/2007 15:45:14.823 CCM|StationD: (0000226) StopTone.<br>03/28/2007 15:45:14.823 CCM|StationD: (0000226) SetLamp mode=1, stim=9 stimInst=1.<br>the the other normal stuff i've seen before when a call shuts down, closes channel, stops transmission,etc.
<br>Further down it closes out the gateway connection, the PRI message indicates normal call clearing, and it looks like callmanager is closing the MGCP connection.<br><br>Does anyone know if there is some place to look for the cause in an IPCC express log? I looked through the MIVR log but nothing jumped out at me.. but i'm not sure what to look for either.
