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? yes, that is what I think Adam proposed in general. To reiterate, he suggested adding a URI paramter to the URI in the From header field at the gateway device. As I understand it, there are use cases where an authentication service can make a strong assertion of idenity about a URI that has user=phone, so I do not think that has the semantic we are looking for. I think we need another parameter. -- 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
