[Freeswitch-users] onInputCallback unstable in Python

[Adam Wilt]

I'm using builds 10724 and 10914 to place an outbound call from the
FreeSwitch console and use the onInputCallback functionality. My goal is to
get mod_vmd working for me.

When I run my script and press a touchtone to invoke the callback function,
I get some unstable behavior; sometimes it works fine, sometimes I get a
core dump (send me an email at wiltingtree at gmail.com if anybody wants the
core dump),  sometimes it gives me the following error:

   TypeError: onInputCallback() takes exactly 3 arguments (0 given)

In the documentation onInputCallback() takes 3 arguments, and I don't see
how it would be very useful with zero.

Here is a test script I put together which shows this behavior:

import os
from freeswitch import *
def onInputCallback(session, what, obj):
  consoleLog("INFO","IM IN THE CALLBACK!\n")
  return("continue")

def fsapi(session, stream, env, args):
  consoleLog("INFO","Hello there!!!\n")
  session =
Session("{ignore_early_media=true}sofia/gateway/gafachi/1xxxxxxxxxx")
  session.sleep(500)
  session.setInputCallback(onInputCallback)
  session.streamFile("/root/intro.wav")
  consoleLog("info","Bye!\n")
  session.hangup()
  return(session)
