External Module allows you to use channel or global scripts in Yate.
These modules can be started from Yate and communicate through pipes to the extmodule.
They can also be started from outside Yate and connect to a TCP or UNIX socket if a listener is configured.
You can read more about how modules communicates to Yate engine using the external module protocol.

IMPORTANT: If an external module fails to start the exact reason why is not displayed in rmanager.
You should instead examine the logs that will hold the reason the exec() has failed.
