[Freeswitch-users] How to delay setInputCallback() while playing audio?

[Muhammad Naseer Bhatti]

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() ?
