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.
