ACM in SIP-T
« on: September 19, 2015, 02:08:34 PM »
Hi all,

I have this voicemail application which receives a SIP INVITE with embeded IAM from a PSTN switch.
My application needs to respond with an 183 session progress with an embeded ACM to open audio channel.
Later on, I need to send ANM so that billing process can begin.

any pointers on how to do this?
