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:

• Playback started
• Playback ended
• DTMF
• Gather ended
