What is Asterisk?

Asterisk is a software implementation of a telephone private branch exchange (PBX).

It is a single transmission channel between two points, each point being either the switching center or the node.

What is an Outbound Route?

An outbound route defines which trunk on the PBX a call may route over, determined by the dialled number.
