Karthik, 486 would be appropriate. We used to return the latest final response in such situations.

Term PCSCF receives 305 with 2 contacts only. Term PCSCF initiates a call to first contact and receives 486. Term PCSCF recurses to the next contact and again receives 486. What is the best response to be forwarded to the originating side? I read the statements from 3261, sec 16.7 and not clear about the decission. sub section 4: If the proxy recurses on all of the contacts in a 3xx response, the proxy SHOULD NOT add the resulting contactless response to the response context. sub section 6: If no 6xx class responses are present, the proxy SHOULD choose from the lowest response class stored in the response context. Moreover I prefer forwarding 486 in this case, as some IMS features are based on receipt of 486 like call completion for originating users and call forwarding on busy subscriber for terminating users. Please let me know ur comments.
