This is the default when there is no "user" parameter in the URI, and it, means that the user part or the URI is an identifier at the host being addressed in the host porition of the URI. > And user=<other-user> RFC4967 is the other defined one. Also note while on the subject, tel URI's SHOULD be a global-number (+xxxx) or have a phone-context parameter, so: sip:[email protected];user=phone is wrong, and should either be: sip:[email protected];user=phone (which is the same as tel:+441234567890) or sip:441234567890;[email protected];user=phone (which is the same as tel:44123456789;phone-context=mydomain.com) note however that 2806 (which 3261 references for telephone-subscriber) does not MUST the context parameter, only SHOULD - however rfc3966 (which updates 2806) makes the phone-context parameter a MUST. ~ Theo _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
