agiテスト用extensions.conf

extensions.conf

exten =>1200,1,Answer()
exten =>1200,n,agi(agitest0.py,"こんにちは、東京")
exten =>1200,n,Verbose(返り値は、${retval})
exten =>1200,n.Hangup()

/var/lib/asterisk/agi-bin以下に配置する。

agitest0.py

# !/usr/local/bin/python3.6
from asterisk.agi import *
import sys
agi = AGI()
para=sys.argv[1]
agi.verbose(para)
agi.set_variable('retval', para)

なりエラーとなる。
