This sample program refers to a note called “Regex” and matches using regular expressions. The program processes matching data strings in all rows in order starting from the top row. When the program finds a matched row, it returns the matched character strings inside parenthesis ( ). When the program can not locate a matched row, it returns null. (When null is returned, the patterns are considered mismatched.) The content of the note is cached in the variables. When a note is renewed, the program will re-read the content.

 

 

2. Example of ARS Setup

Set the following fields in ARS route’s Patterns > [Matching patterns]. Choose appropriate patterns (IN or OUT) depending on the environment.

[Matching Patterns]

From
To	sip:(.+)@
User
Plugin	yourpackage.ARSMatchingSample regex
Param	&t1
Return	(.+)

[Deploy Patterns]

From
To	sip:&p1@domain.com
DTMF
Target

In the above example, user SIP ID in To header is set as a parameter “&t1“.　The return value “&p1” is drawn out and set in [Deploy Patterns] To header.

 

 

3. Example of Notes Setup

Select the menu [Notes]. Brekeke PBX plug-ins can use the text in the notes.

Name	Description
Name	Name of the note.
Description	A brief description of the note
User access level	Access level Select from “No Access”, “Read only”, “Read/Write”
Note	Text field where you can write your own notes.

 

Contents of the note “Regex“:

^1650(.+)$
^1888(.+)$
^1800(.+)$

When the number is starting with “1650”, “1888”, or “1800”, the rest of the number in the parentheses will be drawn out as return value.
