i have a question regarding signalig in asterisk.
I have a queue, and i want to charge the customer only when agent picks up the phone. So I’m using this context:
exten => _X.,1,Progress()
exten => _X.,n,Playback(hello_message,noanswer)
exten => _X.,n,Queue(DISP)
So after i receive INVITE from provider, I’m sending back 183 response (Session in progress), and after that RTP(early media) with welcome message. The problem is that after the welcome message is played, after call enters the Queue, asterisk send back 200 as a response, and that message start billing process.
So is there any way that i can send 180 (ringing) until agent answers the phone?
Thanks for any help!
