I'm not aware of any sample code that exists for ExternalIVR. There is
not further information beyond the README file that documents the
protocol; it's much simpler than AGI so there's not much need for
anything beyond that.

It will not really be any more efficient than AGI, but it also has far
less flexibility: it only supports DTMF detection (non-interrupting,
unlike AGI), file playback and hangup. There is no ability to run
dialplan commands, transfer calls or get access to the audio stream.
