It's actually called session progress/inband progress or something along those lines. It allows you to send audio to the caller before actually answering the channel. I know that some providers do support this, but yours may not. I would first run a test using the Playback application with the noanswer option and see if audio is heard. If not then you may want to talk to your provider and see if they allow you to do it. > > -- > Peng Yong > Joshua Colp Digium _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
