Outbound Route

An outbound route works like a traffic cop giving directions to road users to use a predefined route to reach a predefined destination.

Outbound routing is a set of rules that the PBX uses to decide which trunk to use for an outbound call. Having multiple trunks allows you to control cost by routing calls over the least costly trunk for a particular call. Outbound routes are used to specify what numbers are allowed to go out a particular route.

How does an outbound route work?

Every time you dial a number, PBX will do the following in strict order:
  • Examine the number you dialed.
  • Compare the number with the pattern that you have defined in your route 1 and if matches, it will initiate the call using that trunk. If the route 1 does not match, it will compare the number with the pattern you have defined with route 2 and so on.
  • Pass the number to the appropriate trunk to make the call.
