As you quoted, "The caller's UA MAY send a BYE for either confirmed or early dialogs" and "The BYE request is used to terminate a specific session or attempted session". The offer-answer status is irrelevant; UA1 can send BYE once the early or confirmed dialog is created. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
