Really? does that PROGRES message mean that the call is being handled by a voicemailbox? or does it mean just that the called is generating early media? > Can somebody please explain to me how this is message is handled in SIP > ? Early media does exist in SIP (183 Session Progress with SDP) but it doesn't mean nothing related to voicemailbox. It just means that the called is sending RTP traffic without answering the call. -- 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
