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
