Hi, In RFC 3261
Contact 1xx - - - o - - Contact 2xx - - - m o o For there i guess it's optional, but no the case: UA1 -> UA2 UA2 sends ringing without Contact UA1 created early dialog, but wants to terminate it, it must send BYE ...... no contact header what should do ? _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
