Abstract
Contact information in SIP signaling messages is modified at each in-path network device during the signaling process (along with storage of mapping information) to allow the in-path network devices (and proxy server) to identify the next (or previous) hop device in the path, and thus, maintain the path taken by signaling messages early on during the signaling process. Subsequent request and response signaling messages transmitted during the session follow this path, which ensures that the in-path network devices remain in the SIP signaling path.
