Dial Plan Syntax

This page describes the syntax that you can use when adding dial plans.

Syntax for Conditions (Called number matches)

When you configure the condition for a dial plan rule, you may want to specify a pattern for the called number rather

than specifying any of: called number, no called number or the exact called number.

The table below describes the syntax you can you to express a pattern for the Called number matches field in the

condition of a rule:

Syntax Description Example

Numbers 0 to

To match a specific number,

enter that number.

Example: to match calls to "001234", type 001234. The

condition will match that and only that number.

D To match any digit, use the

wildcard character D

Example: to match any number that starts with "623" followed

by exactly two more digits, type 623DD. This condition will

match "62300", "62323", "62355", "62399", etc. but not "623"

or "623233".

? To match once or zero times,

use ?

Example: "6?" means match one 6 or no 6s, and is useful when

used with the wildcard "D" where you do not know how long a

number will be. The expression: "67800D?" will match "67800"

and "678004" but not "67800666".

+ To match once or more, use + Example: "5+" means "match at least one 5, but possibly

more".

* To match zero or more times,

use *. This is useful when used

with the wildcard: "D*" means

"match any digit, any number of

times".

Example: to match any number that starts with "01", has any

amount of digits in the middle, and ends with "5", type 01 D*

() Parentheses indicate substitution

groups. To include any of the

incoming called digits in the

outgoing called number, enclose

them in parentheses. Note that

if you wish to include the

complete number, you do not

need to enclose the whole

expression in parentheses.

Example: to match any number starting with "678", then

followed by a number of other digits, and you wish the final

digits to form part of the called number, type the expression:

678 (D*). This will match "6780000", "678123", "6789999"

etc. but not "775000".

Syntax for Actions (Call this number)

When you configure the action for a dial plan rule, you may want to specify a pattern for the number to call, rather than

specifying any of: call original called number, reject the call, or the exact number to call.

The table below describes the syntax you can use to express a pattern for the Call this number field in the action of a

rule:
