[Freeswitch-users] Help with Using Mod_AVMD

[Dave]

Hello, 

I am creating an external application that uses FreeSWITCH ESL to initiate an outbound call and then run a LUA script.  Within the LUA script I am executing AVMD. I want to see if its a human or voicemail on the other end.  The outbound call is made and the LUA script executes.

Currently I would just like to see a consoleLog entry made by the onInput function in the LUA script, but that function does not seem to be called. AVMD starts the file is streamed then AVMD stops. As shown in the log.

I think I'm missing something.
