Abdul,

I already answered this question here

## CI 2 (21384620 ##
You can find your CI 2 in either of the following places..

##1 LBMIF process that associates the first call leg (CI1 to the 2nd call leg, CI 2)

00331062.001 |22:51:23.069 |AppInfo |LBMIF: CI: 21384619 ASSOC 21384620

or you can find it in the From header of the outbound INVITE to called phone

INVITE sip:52f81139-c8eb-3de2-3d4c-af5b05043fc1@10.173.247.116:5060;transport=udp SIP/2.0
