passing values from dialplan to python agi script

Below is my python agi script. I'm trying to pass a value from dialplan to agi script and trying to print the value through the script. Everything is working fine but the value is not passing to the script. Please let me know if anything went wrong in it.


from asterisk.agi import *

agi = AGI()

agi.verbose("python agi started")

phone_exten = agi.get_variable('PHONE_EXTEN')
agi.verbose("phone number",phone_exten)

agi.set_variable('EXT_CALLERID', '1')

Dailplan code:

exten => _X.,1,Goto(s,1)
exten => s,1,set(PHONE_EXTEN=0904)
exten => s,2,AGI(first.py,${PHONE_EXTEN})
exten => s,3,NoOp(${EXT_CALLERID})
exten => s,4,Hangup()

This question is seeking debug help, so it's off topic. But okay.

How to debug AGI script correctly:

  1. Stop asterisk service

  2. Start asterisk service in console using asterisk -vvvgc. This one is required to see error pipe of script.

  3. in asterisk console enable agi debug

    agi set debug on
  4. run script
