 * Unit test for SipRouter::proxyMessage

 *  These tests use only loose routes because the adjustment of a strict-routed message into
 *  a loose-routed message is tested in sipXtackLib/src/test/net/SipProxyMessageTest
 *  Similarly, the detailed testing of matching for forwarding rules is done in the
 *  ForwardRulesTest in this directory.
