Interface TraceMessageListenerFactory

public interface TraceMessageListenerFactory

TraceMessageListenerFactory allows clients to reuse the default trace message listener implementation behaviors by creating an instance and delegating to it. Note that instances created by the factory are not registered with the server to receive callbacks upon SIP message arrival and departure. An instance of the factory implementation can be found in the servlet context for all SIP servlets by looking up the value of attribute TraceMessageListenerFactory.TRACE_MESSAGE_LISTENER_FACTORY
