Gather using audio

POST 

/calls/:call_control_id/actions/gather_using_audio

Play an audio file on the call until the required DTMF signals are gathered to build interactive menus.

You can pass a list of valid digits along with an 'invalid_audio_url', which will be played back at the beginning of each prompt. Playback will be interrupted when a DTMF signal is received. The Answer command must be issued before the gather_using_audio` command.

Expected Webhooks:

  • call.playback.started
  • call.playback.ended
  • call.dtmf.received (you may receive many of these webhooks)
  • call.gather.ended
