RegEx

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

You can mix rule types. You can create a From TelURI table that uses rules based on Pattern and rules based on RegEx.
