[Freeswitch-users] mod_avmd

[Michael Collins]

Bernard,

Keep in mind that avmd is non-blocking, that is, it won't cause your
dialplan or script to pause while it is attempting to detect the beep. Your
dialplan will keep doing what it normally does, and if avmd detects a beep
then it will throw an event which you catch and handle in your onInput
function.
