You can use the SIP Tracing feature or SIP Tracer to trace the SIP messages exchanged between the Session Manager server and remote SIP entities. SIP Tracer also logs the SIP messages that are dropped by any component such as SIP Firewall. You can trace all messages related to a user, for a call, or for the selected Session Manager instance.

The SIP tracer user interface has the following components:

• Tracer Configuration: Defines the characteristics of messages to be traced for the capturing engine in the security module.

• Trace Viewer: Displays the captured SIP messages.

For more information about the SIP Tracing, see Maintaining Avaya Aura® Session Manager.
