That can't be quite right. The registrar might support keepalive, but the edge proxy might not. I believe Rohan's explanation indicated that the Require: outbound would only be in the 200 OK response to REGISTER if both the edge proxy and the registrar support it. > So using your terminology: If this specification is supported by the UAC, the edge proxy (if present) and the registrar, then there will be a Require: outbound in the 200 response to the Registration indicating that the UAC MUST do keep-alives as per section X.Y. -- Dean _______________________________________________ Sip mailing list https://www.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
