Tracing a Session Initiation Protocol (SIP) container on Liberty
You can trace a Session Initiation Protocol (SIP) container, starting either immediately or after the next server start. This tracing writes a record of SIP events to a log file.
Procedure
In the server.xml file, add a logging element
and specify tracing for the SIP container by setting
traceSpecification="*=info:com.ibm.ws.sip=all".
<logging logDirectory="${server.config.dir}/logs" traceFileName="trace.log" traceSpecification="*=info:com.ibm.ws.sip=all"/>
