Hi All,
Is is mandatory that the To Tag must be included by the UAS in the 200OK(CANCEL) even if the dialog is not established yet? I.E, as below: UAC UAS |---------- Invite ------------------------------->| |<--------- 100 Trying -------------------------| |----------- CANCEL ------------------------->| |<----------- 200OK(CANCEL, To Tag)-----| alex _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
