Asterisk 不会通过 AGI 记录对话

Question

from asterisk.agi import *

agi = AGI()
agi.verbose("python agi started")
agi.record_file('/tmp/qwerty', timeout=10, format='gsm', escape_digits='0')
agi.hangup()

I'm trying to write a conversation to a file. An empty file is created (of zero size, but no write occurs). Immediately after lifting the answer, the connection is broken.

My extension:

[test_forcall]
exten => 111111,1,Answer()
exten => 111111,2,AGI(asteriskAgi)

Agi debug:

The realization on Golang behaves similarly

Answer 1

It worked! When I set the timeout to -1, but still I do not understand why it does not work when the timeout is > 1

agi.record_file('/tmp/qwerty', timeout=-1, format='gsm', escape_digits='0'
