Asterisk Gateway Interface (AGI)

A simple AGI implementation is provided below, demonstrating how to handle requests from Asterisk, like, as illustrated, answering a call, playing a message, and hanging up:

#!/usr/bin/env python
import pystrix

if __name__ == '__main__':
    agi = pystrix.agi.AGI()

    agi.execute(pystrix.agi.core.Answer()) #Answer the call

    response = agi.execute(pystrix.agi.core.StreamFile('demo-thanks', escape_digits=('1', '2'))) #Play a file; allow DTMF '1' or '2' to interrupt
    if response: #Playback was interrupted; if you don't care, you don't need to catch this
        (dtmf_character, offset) = response #The key pressed by the user and the playback time

    agi.execute(pystrix.agi.core.Hangup()) #Hang up the call
