[Asterisk-Users] Detecting answer supervison from an AGI app

[hwstar at rodgers.sdcoxmail.com]

I've got a dumb Western Electric payphone and some homebuilt hardware to control the coin relay which is accessible to Asterisk through the AGI interface. I'd like to be able to set the state of the coin relay to collect at the end of a call if a called party answers.

[Hey, I admit this project is being persued just for the fun of it ]

Looking through the documentation, there is a way to get channel state, but it only tells you that the channel is
bridged and does not tell you the called party has answered.

Is there another interface (unix sockets maybe?) which I can
use to query the answer supervison state for a given channel?

Steve.
