Trace of a phone call

With the attached trace you can see a phone call from packet 710 14:06:43.761721 192.168.140.231 192.168.100.231 H.225.0 1012 CS: setup OpenLogicalChannel CS: setup OpenLogicalChannel

To me it looks like 1720 is open and responding, Alcatel says differently and that's the problem.

From a phone call perspective the extension is dialed from 192.168.140.231's location to 192.168.100.231 and the call connects, there's dead air for about 5 seconds, then the call disconnects.

How can i use this trace to figure out what's going on?

Thanks in advance!

Oh how do i attach?
