> NO, IT can generate 180 with SDP as default... IMHO there is no difference at all between a 180 and 183 both with SDP. Does a 180 with SDP mean that the UAC could choose to render the real audio or internal artificial ringing? If so, how the UAC would know if the received early media is just a real ringing or a voice message "you have no credit to call, please pay or die" ? -- Iñaki Baz Castillo <i...@aliax.net> _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
