Asterisk. Listening through Spy, I need to play the file asynchronously, how?

Question

Asterisk

Listening to Spy I need to asynchronously play the file, how?
The situation is as follows - the control operator, listening to the channel (knowing the channel name), having heard a certain signal, must start playing a specific sound file. Where to dig?

Answer 1

You can start playing the recording in the channel like this, or the same thing through AMI.
sudo asterisk -rx "channel originate CHANNEL application Playback /etc/alert.wav"'
