Call Trace Tool
Call Trace Overview
The graphical call trace application traces calls (or message sequences) across
all links and groups the messages together. It is
therefore a very powerful facility for troubleshooting, particularly since it
operates in both real-time and post-capture modes.
The application produces a user-configurable window which contains one line
for each call. For example in the case of ISUP, this window would typically
show:
Call identifier
Call status
Call duration
Call setup time
Call cleardown time
Called party number
Calling party number
OPC/DPC/CIC
Release cause
Graphical representation of call phases
