The contact's validity depends upon the ambiguous meaning of user=phone. The user=phone is present; however the user portion is not a valid telephone-subscriber per RFC 2806/3966. Unfortunately since I don't think that sipcore has clarified the meaning of user=phone, you should likely accommodate user=phone without requiring the user portion to be present and/or decode as telephone-subscriber. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
