Pattern

Use Pattern when you want to use a digit string as a way of detecting the presence of a specific sequence of digits in an incoming dial string. When you select Pattern you can create a matching string based on literal digits (0 through 9), one character literal (the #), and one special character, the asterisk (*) which will match any digit or sequence of digits. If you select Pattern, valid dial string characters are: all digits (0-9), the number sign (#), and the asterisk (*).
