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
•
