Outgoing Calls

You can configure outgoing calls settings in Services ‣ IPBX ‣ Call Management ‣ Outgoing calls.

An outgoing call is composed with a definition of a outgoing route (the extension patterns that should match) and a destination (a trunk owned by a media server).



A route can define

  • Priority: A number that will prioritize a route compare to another one, if both routes are available for a same matching extension.
  • Call Pattern:
    • Extension: The pattern that will match an extension. More details on the Asterisk wiki.
    • (advanced) RegExp: Transformation to apply on the extension once route is found.
    • (advanced) Target: Allow to perform filtering like stripping number based on transformation Regexp.
    • (advanced) Caller ID: Override the presented number once call is performed.
  • Media server: define the route only for specific media server.
  • Context: define the route only for specific context.
  • Internal: set the route to forward the internal caller’s caller ID to the trunk. This option is useful when the other side of the trunk can reach the user with it’s caller ID number.

Here some examples of how you can take advantage of RegExp and Target:

Regexp Target Result
(.*) \1 get whole called number
(.*) 445 Replace called number with 445 number
14(.*) \1 Delete 14 prefix and keep only following part
14(.*).. \1 Delete 14 prefix and last two digits and keep the rest (e.g. 1455660 → 556)
(.*) 33\18 Prefix the called number with 33 and suffix it with 8
14(.*).. 33\18 Delete 14 prefix and last two digits and then prefix the called number with 33 and suffix it with 8 (1455660 → 335568)


Once route is defined and therefore can be selected if an extension match the route, you need to set the wanted destination. A route destination is materialized by:

  • Trunk: SIP or Custom trunk that will be used to reach desired network.
  • Subroutine: Subroutine to apply once route has been selected.

Rights and schedules

A route can define rights aka call permissions, it means that a call can be discarded if missing the right to use this route. The same applies for schedules where you can define time slots of availability of the route.
