Just use asterisk/freeswitch/sems/whatever to playback media and you don't have to touch SDP in kamailio to do this. In order to avoid answering the call you have to generate the audio without a 200 OK, so your option is 183 Progress, which asterisk will do for you with Playback(foo,noanswer). _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
