We need an RFC 3262 for resolving Tel: URLs. I suspect it looks like: 1) Consult your configured routing information. If that fails, 2) Do an ENUM lookup. If that fails, 3) If you have a telephony routing table (like TRIP), consult that. If that fails, 4) Use your default telephony route; send it to a gateway. Or perhaps these are reorderable approaches, and each node needs something like an nsswitch.conf file to tell it which routing order to use? -- 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
