Description (partial)

Symptom:

IPCC Mobile Agent login may fail with "Timeout limit was exceeded" even though the given LCP/RCP CTI Ports show registered within the CCMAdmin web page.

The following signature may be found the CTI SDL traces.
=====
021262694| 2009/11/13 01:29:48.073| 007| SdlSig-O  | CtiLineOpenLineReq                    | NA RemoteSignal               | CTIRegistrar(7,100,*,*)         | CTIDeviceLineMgr(7,200,18,1)    | (0,0,0,0).0-(*:*)                       | [R:NP - HP: 0, NP: 0, LP: 0, VLP: 0, LZP: 0 DBP: 0] mAsyncResponse = 805626 Name=LCP5000F66001 LH=7|375 Line=66001 Partition=PREVIOUS-PARTITION TimeOut=0 FilterBitmap=0x98 Auto Accept Status=0
=====
Note: The Partition value shown in the above signal will indicate the name of the previous partition assigned to the CTI Port line/DN.  And there is never another attempt by the application or CTI Manager to open the line with the newly configured partition.

This results in the following error response.
=====

=====

The following two error signals may also be found in the CTI SDL trace.  The second error signal listed below may also be thrown as a system alarm in the CUCM application event log and as a SyslogSeverityMatchFound alert in RTMT with corresponding email notification if email notification is configured.

=====

Conditions:

This problem may occur if the partition on the line of a CTI Port (LCP or RCP) is changed to a new value while the CTI Port is currently registered/InService and working problem.  The PG may not receive notification of the partition change.  This may allow the "device" to be in a registered/InService state, but the "line" may be stuck in an "OutOfService" state.
