If a UA sends a REGISTER with say a@b.c:dddd as a contact (binding) would it ever be conceivable that a registrar would return anything other than that binding in a 200 OK (I am assuming here that this UA is only registering once).
More specifically, Has anyone ever seen the contact of a 200 OK return URI info about the proxy / registrar itself? i.e. contact in 200 OK = a@regip:regport If so, can anyone indicate why this would be desirable? I was under the impression that RFC3261 Sect 10.3, subsect 8 makes it explicit that a proxy / registrar should return (in the contact) the bindings (typically 1 in my simple scenario) that is basically a reflection of the contact sent in the original REGISTER. Typically, what use if any is made of the contact info passed back to a UA in the 200 OK? Thanks for any clarification. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
