Hi Romel, If the user(UAS) is not currently registered to the network means the user's(UAS) contact is not present in the location service. I think for such a case, proxy should send back 404 Not Found response.
As per section 16.5 for RFC 3261 "If the Request-URI indicates a resource at this proxy that does not exist, the proxy MUST return a 404 (Not Found) response." Thanks and Regards, Rajat Chandna ________________________________________ From: [email protected] [[email protected]] On Behalf Of Romel Khan [[email protected]] Sent: Thursday, August 11, 2011 5:58 AM To: [email protected] Subject: [Sip-implementors] Response code sent by proxy to caller when UAS not registered What SIP code should a proxy send back to a caller if the UA the caller is trying to reach is currently not logged in?
