I think they should add it as a URI-param, or even URI-username param. Both because it's about the type of username or URI itself, and because then rfc4474 would actually include that param in its signature, so no one in the middle could change it. Of course that uri-param already exists: user=phone. Or is that not the right semantic? -hadriel _______________________________________________ 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
