Following this thread, and building on this idea, you can pull the error response code up, and in Wireshark (Ethereal), select on the message (for example 483 too many hops). Then select the CALL-ID in the SIP Header and right mouse click. Select APPLY AS FILTER and SELECTED. That will put that whole call in view (it is a filter). Then select STATISTICS:FLOWGRAPH for the displayed packets.
Another thing to try is ANALYZE:VOIP CALLS, which gives all calls successful and rejected, in a summary format for the entire captured trace. Let me know how it works.

It is similar to SIP Scenario Generator. Alternatively (and a cleaner solution), you can filter Ethereal to capture only 4xx/ 5xx (assuming these are the failed calls you are talking about). You can set it via Ethereal Capture -> Expression & then use SIP Scenario Generator/ SIP Analyzer to draw the call flows for the completed calls (INVITE -> 1xx -> 3xx/ 4xx).

I need to find out the broken calls. For generating the call flow diagrams I used SIP Scenario generator but its too difficult to point the broken calls as there are too many calls. and only a few calls are broken. (only 10-12 out of a few thousand) Can some body suggest me some way or some tool in which we can generate call flow diagram of only unsuccessful calls.
