Dial plan is a string of characters that governs the way your SIP-T20P/SIP-T20 IP phone

processes the inputs received from your phone keypad. The SIP-T20P/SIP-T20 IP phone

supports the following dial plan features:

 Replace Rule

 Dial-now

 Area Code

 Block Out

The basic expression syntax you need to know:

The dot ‖.‖ can be used as a placeholder or multiple placeholders for any

character. Example:

―12.‖ would match ―123‖, ―1234‖, ―12345‖, etc.

An ―x‖ can be used as a placeholder for any character. Example:

―12x‖ would match ―121‖, ―122‖, ―123‖, etc.

[]

The square brackets ―[]‖can be used as a placeholder for a single character

which matches any of a set of characters. Example:

―91[5-7]1234‖ would match ―9151234‖, ―9161234‖, ―9171234‖.

()

The parentheses ―( ) ―can be used to group together patterns, for instance, to

logically combine two or more patterns. Example:

1 2 ... 51 52 53 54 55 56 57 58 59 60 61 ... 125 126
