The VoIP Log

The VoIP Log is a per-call event log that records major SCCP/SIP and RTP events and measurements.

To access the log, do the following:

1.From the Main menu, select VoIP/Toolkit.

2.On the VoIP/Toolkit menu, select VoIP Log to display the VoIP Log screen.

You can use the VoIP Log to watch events that occur as the phone boots up and subsequently to monitor a call that is in progress.

During the boot process, the log captures the exchanges between the phone and the network. When the phone goes “off hook”, the boot information is cleared and transactions between the parties are recorded. Call quality and QoS statistics are logged for both sides.

Figure 7-3 shows an example of a VoIP Log entry. Depending on the length of a call, the VoIP Log may have several pages of screens. To page up or down, press the Up or Down ab arrow keys.

Appendix C contains sample SCCP and SIP boot and call logs. The logs are fully commented to give you idea of what happens during the boot process and while a call is in progress. You can also look at the parameters that are tracked from the start of a call until the far-end phone goes “on hook”.
