Description

Trying to use log4j 2.x and the log4j-1.2-api (to emulate log4j 1.2 support), starting a route with camel-sip fails to initialize:

Failed to create Producer for endpoint: Endpoint[sip://test@... stackName=client]. Reason: javax.sip.PeerUnavailableException: The Peer SIP Stack: gov.nist.javax.sip.SipStackImpl could not be instantiated. Ensure the Path Name has been set.

Further down the stack trace, it has:

The original log4j 1.2.x JAR needs to be on the classpath to provide that class.

The problem is at SipStackImpl.java:666 which appears to be in the dependency jain-sip-api-1.2.jar
