I am new to freeswitch. I am trying to send a message to voicemail using avmd for voicemail detection, here is the code which i am using with originate command:

from freeswitch import *

# WARNING: known bugs with hangup hooks, use with extreme caution
def hangup_hook(session, what):

    consoleLog("info","hangup hook   %s!!\n\n" % what)
    return

def input_callback(session, what, obj):

    if (what == "dtmf"):
        consoleLog("info", what + " from callback " + obj.digit + "\n")
        return
    elif (what == "event" and session.getVariable('avmd_detect') == "TRUE"):
        consoleLog("info", "Voicemail Detected\n")
    return "true"

def handler(session, args):

    session.answer()
    session.execute("avmd", "start")
    session.execute("sleep", "25000")
    callback = session.setInputCallback(input_callback)
    consoleLog("info","callback returned %s!!\n\n" % callback)
    while session.getVariable('avmd_detect'):
         session.execute("speak", "flite|kal|'Hi how are you'")

    session.execute("avmd", "stop")
    session.setHangupHook(hangup_hook)
    session.hangup() #hangup the call


I can see avmd getting started but it does detect any beep. Is there a simpler way to check if avmd is working without using 'originate'?

Thanks
