<DIV dir=ltr><FONT face=Arial color=#000000 size=2>Hello;</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>I had a similar Problem but not realted to IPCC at all. I have a PSTN gateway softswich system (PGW). I can give u some clues. try to know which party is closing the call by looking at the dest_cause and orig_cause of the CDR of the call @ CM and see what that cause means. my problem was that I had a server (involved in call processing) that have 2 network interfaces and they was not configured correctly to run with each other, so the call drop disappers when I remove one of the cables. I know maybe my case is a differenet one but just wanted to help.</FONT></DIV>

<DIV>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. <BR><BR>-- <BR>Ed Leatherman<BR>Senior Voice Engineer<BR>West Virginia University<BR>Telecommunications and Network Operations </DIV></BODY></HTML>
