Forks a process to run the specified ExternalIVR-compliant command, and starts a generator on the channel. The generator’s play list is controlled by the external application, which can add and clear entries via simple commands issued over STDOUT. The external application will receive notifications of all DTMF events received on the channel, and notification if the channel is hung up. The application will not be forcibly terminated when the channel is hung up.

See doc/externalivr.txt in the Asterisk source code for the specification of the ExternalIVR interface.
