pycall validation error

[pd-Shah]

im trying to run these lines of code in atom and python3.6 :

from pycall import CallFile, Call, Application
import sys

def call():
        c = Call('SIP/200')
        a = Application('Playback', 'hello-world')
        cf = CallFile(c, a)
        cf.spool()

if __name__ == '__main__':
        call()

and my sip.conf and extension.conf are shown below:

sip.conf

main.py

from pycall import CallFile, Call, Application
import sys

def call():
        c = Call('SIP/200')
        a = Application('Playback', 'hello-world')
        cf = CallFile(c, a)
        cf.spool()

if __name__ == '__main__':
        call()

finally i faced with this error:

Traceback (most recent call last):
  File "/home/pd/gits/voiphone/main.py", line 12, in <module>
    call()
  File "/home/pd/gits/voiphone/main.py", line 9, in call

  File "/home/pd/telephonerelayEnv/lib/python3.6/site-packages/pycall/callfile.py", line 100, in buildfile

Run as asterisk user.

sudo su asterisk -s /bin/bash

python

from pycall import CallFile, Call, Application
call = Call('SIP/flowroute/18882223333')
action = Application('Playback', 'hello-world')
c = CallFile(call, action)
c.spool()
