Class SIPBalancerForwarder

java.lang.Object
  org.mobicents.tools.sip.balancer.SIPBalancerForwarder

All Implemented Interfaces:

java.util.EventListener, javax.sip.SipListener

public class SIPBalancerForwarder
extends java.lang.Object
implements javax.sip.SipListener

A transaction stateful UDP Forwarder that listens at a port and forwards to multiple outbound addresses. It keeps a timer thread around that pings the list of proxy servers and sends to the first proxy server. It uses double record routing to be able to listen on one transport and sends on another transport or allows support for multihoming.
