Of course no. URI in From means an AoR while URI in Contact means a definitive location. Contact header in a 3XX response contains, typically, an AoR, but Contact in a request/response forking a dialog needs to be a *real* location and not an AoR. Contact can't never be populated from From header. It makes no sense at all. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
