How can a SIP trace be captured on the switch?

When setting up a new SIP trunk with a provider or troubleshooting call failures it is important to be able to capture a signaling trace of an outbound call. This is also important when troubleshooting SIP registration issues with a new provider.

In Asterisk for example, turn on SIP debugging via the Asterisk CLI using the sip set debug commands.

Sip set debug peer on – turns on SIP debugging globally showing all SIP traffic to and from the Asterisk gateway.

Sip set debug IP xxx.xxx.xxx.xxx – debug only message to and from a particular IP address.

Sip set debug off – Turns off all SIP debugging.

Please be familiar with how to turn on debugging.

If enabling debugging on the switch is not preferred, use a network protocol analyzer such as Wireshark to capture the SIP and media traffic on the calls.
