CVP call server logs
 Hi All,
I am trying to figure out whether caller party(End User) hangup the call first or UCCE Agent.
Attaching CVP call server Logs& UCCE TCD& Route Call Details for your reference.

From the CVP logs, it can be determined which side disconnected the call first. For each call, CVP keeps track each call leg. From Inbound Gateway to CVP is INBOUND leg, rest are OUTBOUND leg. You can then look at which leg the SIP BYE message is received first.
Since you have very basic log enabled, you will not see the exact SIP message. But it can be determined by the outcome of the message. Here is the snippet of the log during the disconnect:
Line 3766: 3083689: 10.180.245.43: Sep 12 2014 12:21:11.293 -0700: %CVP_8_5_SIP-7-CALL:  {Thrd=DIALOG_CALLBACK.6} CALLGUID = CBCCDD8539E811E4A3E2CCEF48565980 LEGID = CC65CE04-39E811E4-87DFD7D1-64B198F2 - [INBOUND] DURATION (msecs) = 25610 - DIALOG TERMINATED. Reason: Q.850;cause=16

The first Termination message came on the INBOUND leg which is the PSTN. That means, PSTN side disconnected the call first.
Hope this helps.
