Hi The question is "What is the response code for a SIP request which was routed to the wrong proxy, e.g. "INVITE sip:[EMAIL PROTECTED]" was wrongly routed to example.com SIP proxy. How should example.com reject the request? 404 or is there a better code - something like "I am not authoritative for this domain"?"
The 502 response description from rfc 3261 "The server, while acting as a gateway or proxy, received an invalid response from the downstream server it accessed in attempting to fulfill the request." In above case, proxy forwards the request and gets invalid response from downstream server. For me the case is proxy is not forwarding the request, before that it wants to reject. Again 403 fobidden description says server understands the request (does not say capable of processing it). If you refer section 8.2.2.1 in rfc 3261, it says if UA determines the To header content of received request does not match with that of current user it should reject wth 403. And above case is similar, the received request is not for the proxy, hence it is logical for proxy to send 403 forbidden.

For me 403 means: "You don't have permission to access this resource, but I'm capable of offering it". Why not a 502? We are speaking about a upstream routing problem, aren't we?
