Dialplan & Trunk Regex

Dialplan Regex examples

tip

For star codes to work in the dial plan, you must configure Star codes that are handled in dial plan. For e.g. set to *67* to allow calls like *6723232323, *67232323232323, etc.

Pattern	Replacement	Example Input	Example Output	Description
\*67([0-9]{6})(@.*)	\*67\1\2	*67112233	*67112233	Caller ID blocking: Preserves *67 prefix with 6-digit number
\#5(011[0-9]{6,20})(@.*)	\1\2	#50113344556677	0113344556677	International dialing shortcut: Removes #5 prefix, keeps international number
^0(9[0-9]{7})(@.*)	+64\1\2	093445565	+6493445565	New Zealand national to international: Converts 0 prefix to +64 country code

Pattern Explanation

• \*67([0-9]{6})(@.*): Matches "*67" followed by exactly 6 digits, captures the digits and any following context
• \#5(011[0-9]{6,20})(@.*): Matches "#5011" followed by 6-20 additional digits, captures the international number and context
• ^0(9[0-9]{7})(@.*): Matches line starting with "0" followed by "9" and exactly 7 more digits, captures the national number and context

Replacement Explanation

• \*67\1\2: Keeps the "*67" prefix, followed by captured digits (\1) and context (\2)
• \1\2: Returns only the captured international number (\1) and context (\2), removing the "#5" shortcut
• +64\1\2: Replaces the "0" with "+64" country code, followed by the captured number (\1) and context (\2)

Trunk Regex Examples

You can use a list of regex expressions to route incoming calls. Below is an example with two separate conditions using space as the delimiter:

!^1?([0-9]{9})$!61\1!t!123! !^0?([0-9]{9})$!61\1!t!123!

Regex Pattern Breakdown

Pattern	Received Number	Final Number Searched	Description
!^1?([0-9]{9})$!61\1!t!123!	1300300300	611300300300	Matches optional "1" prefix + 9 digits, replaces with "61" + captured digits
!^0?([0-9]{9})$!61\1!t!123!	0233445566	61233445566	Matches optional "0" prefix + 9 digits, replaces with "61" + captured digits

How It Works

First regex pattern: When a number like 1300300300 is sent to the PBX (or when formatting is enabled for specific Caller ID display that also formats the destination number), the first regex pattern will replace it with 611300300300.

Second regex pattern: When a number like 0233445566 is sent to the PBX (or when formatting is enabled for specific Caller ID display that also formats the destination number), the second regex pattern will replace it with 61233445566.
