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 |
