Hello everyone,

I was testing the avmd mod, and I found a problem. The voicemail detection starts, but after few seconds (2/3) it stops for 4/5 seconds, and then "misses" the voicemail beep.

I'm using this small script for testing the avmd in python, partly taken from an old email

---

import sys

from freeswitch import *

def input_callback(session, what, obj):

    consoleLog("info", "Callback")

    return "TRUE"

def handler(session, args):

    session.answer()

    callback = session.setInputCallback("input_callback")

    session.execute("avmd", "start")

    consoleLog("info", "AVMD start\n")

    session.execute("sleep", "20000")

    consoleLog("info", "AVMD status %s\n" % session.getVariable('avmd_detect'))

    session.execute("avmd", "stop")

    consoleLog("info", "AVMD stop\n")

    session.hangup()

---

And you can see an example of the console log here

As you can see in the timestamps, it stopped for 5 seconds, and during those 5 seconds probably there was the "beep" which was not caught.

I have checked in the wiki, but I don't see any specific configuration about the avmd, so I don't know where to look for anymore, and online I couldn't find any solution.

If you need more informations I'm happy to provide so.

Thanks a lot.

Best Regards,

Francesco
