I'm from brazil and here we have a lot of early media calls with machine answer(voicemail), I want to detect early media + machine answer and hangup this call , I read about avmd mod and it is a way to detect after answer call and i would like to detect machine before answer, it is possible with freeswitch?  I tought that monitor_early_media_fail was a better way to do it but I don't know how use it because when i tried to use doesn't work, problably I'm using in a wrong way, I used AMD from asterisk to detect Answer machine after Answer... some can help me?

Need to try detect voicemail tone.

Or try play announcement after answer and check voice activity. If voice activity is high, then voicemail

Voicemail is not earlier media. the call is answed. early media is things like ringing or other in band signaling methods like fast busy or ‘not in service’ recordings.

Hello friends,

I would like to know how is the better way to block outbound calls with early media and sip trunk, I have a system for callcenter and I have a big problem with calls in voicemail entering to agents , I tried to use monitor_early_media_fail with ignore_early_media but I didn't have a sucessfull, it is possible to use this function to block it? How can i do it?

My wish is to stop the call when i knew that is a voicemail call.
