Seems that way to me. Any such rule would have to allow for network policy, and there are lots of legitimate policies e.g., least cost routing and the necessity of SIP peering agreements, that would result in its not being followed. In the end this is a business issue not a technical one. tim _______________________________________________ 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
