Matching pattern using RegEx (regular expressions)

Procedure

Select RegEx (regular expression) when you want to use a Java regular expression to analyze an incoming dial string.

In certain cases (especially variable extension), RegEx rules will allow an administrator to minimize the number of rules that must be administered. Regular expressions rely on symbolic notation - grouping of digits and special characters for analyzing incoming dial strings. For example, ([0-5]\\d{0,3}) is a regular expression which matches extensions that start with digits 0 - 5, and are 1 to 4 digits in length. Specifying a minimum, maximum, or delete length do not apply to regular expressions.

noteNote

A From TelURI table in the AE Services Management Console can consist of rules based on the Pattern setting and rules based on the RegEx setting. That is, you can create a From TelURI table that uses rules based on Pattern and rules based on RegEx.
