I disagree. Once you've decided to use an RFC 3261 location service, what you say is probably correct. But the parameter can be used to make an earlier decision to use telephony routing INSTEAD of using an RFC 3261 location service. RFC 3261 says: > In addition to DNS and location service lookups shown in this > example, proxy servers can make flexible "routing decisions" to > decide where to send a request So DNS is clearly a different sort of lookup than "location service". ENUM is a DNS lookup, and I see no reason why "user=phone" is not a valid flag for saying "don't do location service, do ENUM or TRIP or other telephone routing instead". -- 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
