The Req-URI and the To: header may start out the same, but proxies are allowed to replace the Req-URI as they forward the request (RFC 3261, section 16.5 and 16.6). For example, the Req-URI may initially contain the user's Address-of-Record. The proxy server could read the UAS's contact address from the location service and place it in the Req-URI.
It could be the case that the AoR and contact address differ only in user name. -- Gary Cote www.awardsolutions.com _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
