you’d have to handle ignoring for a couple seconds in your callback.. there is no way to delay setting the callback that I can think of.

I guess this would only introduce a silence of 2 seconds. I am trying to play the file but delay DTMF detection for a few seconds. So my file is being played but I want to ignore a few seconds of DTMF inputs for callback function. Can’t think of a better way to do that.

Or something like sched_api_function() which calls the function to detect events?

playbackMessage() function is actually doing session:streamFile(audio_file). Input callback is functioning fine, but I want to delay detection a few seconds somehow.

On the other hand, is there a way to stop a running session:streamFile() ?

Show us how you're doing the playback,  If you're doing session:execute('playback', 'blah.wav'); The input callback won't function you have to use session:streamFile instead.

I am running an IVR which collects DTMF input while the file is being played, written in Lua. I set InputCallback and then listen for DTMF events. If event found, take actions etc. 

    session:setInputCallback("eventHandler")
    playbackMessage (playback_delay)

Facing a strange issues with Verizon where they send a quick RTP Event write after starting the audio, which triggers the DTMF event and bad things happen in my script. This only happens within first 1 to 2 seconds of RTP. How can I have my InputCallback listen for events only after a few seconds while still playing the audio? or do I have to switch to playAndGetDigits() ?
