Outbound rules

Rules for permitted outbound calls can be created in this section.

Rules can be defined as a:

  • pattern (a certain syntax is required - patterns must begin with underlines . E.g.: _0XXXXXXXXX).)
  • regular phone number, containing as many digits as possible (E.g.: 0727123456)

Exten is the actual number dialed via external trunk:

  • ${EXTEN} - Will dial the same number
  • ${EXTEN:2} - Will strip first two characters from the dialed number
  • 0720000${EXTEN} - Will add 0720000 prefix to the dialed number
  • 1234567 - Will dial 1234567 only

Pattern mathcing rules

  • X matches any digit from 0-9
  • Z matches any digit from 1-9
  • N matches any digit from 2-9
  • [1237-9] matches any digit or letter in the brackets
  • [a-z] matches any lower case letter (introduced in which Asterisk version?)
  • [A-Z] matches any UPPER case letter (introduced in which Asterisk version?)
  • . wildcard, matches one or more characters
  • ! wildcard, matches zero or more characters immediately

How to restrict an Outbound route:

The Deny ID field (optional) is used together with the OUTBOUND_DENY variable associated with the user (go to PBX/Users/Edit User).
To ban a route for certain users, set Deny ID, then set OUTBOUND_DENY for each user separately.

Examples - Rules for international outbound routes:

1. Patterns created for each country, for a more granular management of the outbound routes:

2. Unique pattern that allows international numbers to be dialed:

_!XXXXXXXXX!
