It seems strange that it <BR>would be a StationInit message but the timeout is coming from the <BR>StationInit process within the CallManager. CCM/SDL traces from the <BR>same time frame may help to confirm this. A packet capture of the <BR>problem would be best though. <BR><BR>At some point, don't remember when, the KeepAliveAck message was taken <BR>out of the CCM trace. One thing you can do is to go backwards in the <BR>trace from the "Keep alive timeout" message and see when the last <BR>KeepAlive from the phone was. I suspect you will find one missing. <BR><BR>HTH, <BR>Kevin <BR><BR>On Nov 16, 2005, at 3:01 PM, Justin Steinberg wrote: <BR><BR>> I have some phones that periodically reset themselves at random times <BR>> during the day, I even have some instances when the phone reset itself <BR>> while on an active call. <BR>> <BR>> When I look at a detailed callmanager trace i see the following entries: <BR>> <BR>> 11/15/2005 15:21:29.108 CCM|StationInit - Keep alive timeout.: <BR>> 000000741|<CLID::xxxCMPUB01-Cluster><NID::10.xxx.xxx.xxx><CT:: <br>> 2,100,90,1.1122347><IP::10.xxx.xxx.xxx><DEV::SEP000C853Bxxxx> <BR>> 11/15/2005 15:21:29.108 CCM|StationInit - Closing Station connection <BR>> DeviceName=SEP000C853Bxxxx, TCPHandle=000000741, <BR>> IPAddr=10.xxx.xxx.xxx, Port=52056, Device <BR>> Controller=[2,89,737]|<CLID::xxxCMPUB01-Cluster><NID:: <br>> 10.xxx.xxx.xxx><CT::2,100,90,1.1122347><IP::10.xxx.xxx.xxx><DEV:: <br>> SEP000C853Bxxx> <BR>> 11/15/2005 15:21:29.108 CCM|DeviceUnregistered - Device unregistered. <BR>> Device name.:SEP000C853Bxxx Device IP address.:10.xxx.xxx.xxx Device <BR>> type.
