You expect SIP to be a dereference capable protocol? Why? >and puts that into a Location header in an INVITE? INVITEs don't do subscriptions, SUBSCRIBEs do, so this L7 value put into a Location header that's in an INVITE wouldn't create a subscription in the first place. The above offering is to make sure dereferencing is done with HTTP/HTTPS, not SIP. > How is the subscription done with HTTP? It isn't done with an INVITE either. sorry... >-andy > > >_______________________________________________ >Sip mailing list https://www1.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 _______________________________________________ Sip mailing list https://www1.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
