Customizing Your Phone49Dial plan is a string of characters that governs the way your SIP-T22P IP phone processesthe inputs received from your phone keypad. The SIP-T22P IP phone supports thefollowing dial plan features: Replace Rule Dial-now Area Code Block OutThe basic expression syntax you need to know:.The dot ”.” can be used as a placeholder or multiple placeholders for anycharacter. Example:“12.” would match “123”, “1234”, “12345”, "12abc", etc.x An “x” can be used as a placeholder for any character. Example:“12x” would match “121”, “122”, “123”, "12a", etc.[]The square brackets “[]”can be used as a placeholder for a single characterwhich matches any of a set of characters. Example:“91[3-8][0-9]1234” would match “91301234”, “91591234”, “91851234”, etc.()The parentheses “( ) “can be used to group together patterns, for instance, tologically combine two or more patterns. Example:“91([5-7])1(x)” would match “91511”, “91618”, “91715”, etc.$The “$” should be followed by the sequence number of a parenthesis. The“$” plus the sequence number means the whole character or charactersplaced in the parenthesis. The number directs to the right parenthesis whenthere are more than one. Example:A replace rule configuration: Number: "9([5-7]) (.)", Replace: "5$2". When youenter "96123" to dial out on your phone, the number will be replaced as "5123"and then dialed out. “$2” means the characters in the second parenthesis,that is, “123”.NoteYou can configure one or more replace rules to remove the specified string and replaceit with another string. You can configure a pattern with wildcards (refer to the expressionsyntax in the table above), so that any string that matches the pattern will be replaced.This feature is convenient for you to dial out a long number. For example, a replace ruleis configured as “Number: 1” and “Replace: 1234567”, when you try to dial out thenumber “1234567”, you just need to enter “1” on the phone and then press the Send softkey.You can configure the dial plan rules via web user interface only.
