Voice mail detection AVMD

[Jiz]

I am trying to detect voice mail with mod_avmd and play an audio if beep detected to drop a message to voice mail. By following https://freeswitch.org/confluence/display/FREESWITCH/mod_avmd I have managed to install the module and created the dialplan for inbound call. Beep successfully detected and fires an event avmd::beep
Now, how do I play an audio using this event ? i believe some kind of script is needed to listen the event and execute audio play. Anybody can help with the script and how to use it ? or some work around ?


I have another fusionPBX server in production which is working fine this scenario which is deployed by some one else. Is there anyway to figure it out from that server how it works ?

Start by having a look in /etc/freeswitch/autoload_configs/lua.conf.xml and see if a event hook has been set up to handle the CUSTOM event subclass.
Something like:

<hook event="CUSTOM" subclass="avnd::beep" script="some-named-script.lua"/>
