[Freeswitch-users] Hangup_hook is not getting called in mod_python script

[Deepika Yadav]

Since it is a callback mechanism. Before passing to the 4449 extension, the
user simply dials a fixed mobile number, the extension '1234' passes it to
python script incoming_call_handler.py as follows:

*1234 extension in public domain*

<extension name="public_did">
    <condition field="destination_number" expression="^(1234)$">
       <action application="python" data="python.incoming_call_handler"/>
    </condition>
  </extension>

After the* incoming_call_handler.py* hangs it up and initiate a thread to
callback

def handler(session, args):
    callerid =  session.getVariable('caller_id_number')
    number  = (callerid[len(callerid)-10:])
    freeswitch.consoleLog('INFO','Called by %s\n' % number )
    session.hangup()
    new_api_obj = API()
    new_api_obj.executeString("pyrun python.callback " + callerid)


*Callback.py:*
It originates the call by transferring to extension 4449

def runtime(arg1):

    phone_number = arg1[len(arg1)-10:]
    new_api_obj = API()
    command_string = "originate sofia/gateway/MySIP/91" + phone_number + "
4449"
    result = new_api_obj.executeString("reloadxml")
    return_val = new_api_obj.executeString(command_string)

*4449*
4449 calls Sangoshthi_IVR_handler to play IVR menu on call answer

<extension name="record_topic">
<condition field="destination_number" expression="^4449">
<action application="set" data="execute_on_answer=python
*python.sangoshthi_IVR_handler/>*
<action application="sleep" data="30000"/>
</condition>
</extension>

Yes, the python script is running successfully the only thing is when
caller drops the call the hang u callback registered using hangup_hook does
not called.
