I to Originate channels using AMI. When the other end indicates the channel is ringing, I need to do some system notification work.
Everything works great when the ITSP sends a 180 Ringing response. Through AMI events I see the channel state changed and can do the necessary work.
However, when the ITSP sends a 183 with SDP response, there is no notification through AMI indicating anything has changed. Until the channel is answered, rejected, other failure, or ITSP sends 180 Ringing I do not see any updates via AMI events.
I realize the 183 Progress is not a Channel State change so AMI cannot send an AMI event indicating any channel state change. Is there some way to know through AMI whether a 183 has been received?
Have a great day!
