[Freeswitch-users] Lua Script with mod_vmd, setInputCallback doesn't seem to get called

[Matthew Fong]

Hi Michael,

the cell phone carriers in the US use a beep tone that is out of the range
that is typically detected. i've had success using tone_detect rather than
mod_vmd. if my memory serves me correctly 786 is the tone you need to listen
for. the same is true for sprint and t-mobile voice mail beeps
