Call Audio Capturing

Hi, I am new to asterisks and I was running asterisk for the first time. I have installed asterisk 16.6 and freepbx, and I am using Zoiper5 to make calls. I want to capture call audio in real-time using the asterisk dialplan and send that audio stream to another process. However, I was unable to run the dialplan. My extensions_custom.conf file looks like below:


However, the python script does not run when I make the call to extension 2020.

Instead of system app try agi() and enable the debug mode for AGI

I am running agi( in my dialplan now:
the python script is as followed:

#!/usr/bin/env python
import os
import sys

f = open(“demofile.txt”, “w”)
f.write(“Now the file has more content!”)

The dialplan is extensions_custom.conf :


The agi debug from CLI is:

Has your python file executable permission? You can add it by command chmod +x

It looks like what ever executed sent the text string “Saad Akhtar” to Asterisk which violates AGI protocol.
