Customizing Your Phone59Dial plan is a string of characters that governs the way your SIP-T42G IP phoneprocesses the inputs received from your phone keypad. The SIP-T42G IP phone supportsthe following dial plan features: Replace Rule Dial-now Area Code Block OutBasic expression syntaxes you need to know:Syntax Description.The dot "." can be used as a placeholder or multiple placeholders forany character. 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 singlecharacter which matches any of a set of characters. Example:"91[5-7]1234" would match "9151234", "9161234", "9171234", etc.()The parentheses "( )" can be used to group together patterns, forinstance, to logically combine two or more patterns. Example:"([1-9])([2-7])3" would match "923", "153", "773",etc.$The “$” should be followed by the sequence number of a parenthesis.The “$” plus the sequence number means the whole character orcharacters placed in the parenthesis. The number directs to the rightparenthesis when there are more than one. Example:A replace rule configuration: Prefix: "9([5-7])(.)", Replace: "5$2". Whenyou enter "96123" to dial out on your phone, the number will be replacedas "5123" and then dialed out. “$2” means the characters in the secondparenthesis, that is, “123”.You can configure one or more replace rules (up to 100) to remove the specified stringand replace it with another string. You can configure a pattern with wildcards(expression syntax refer to the table above), so that any string that matches the patternwill be replaced. This feature is convenient for you to dial out a long number. Forexample, a replace rule is configured as "Prefix: 1" and "Replace: 1234567", when you tryto dial out the number “1234567”, you just need to enter “1” on the phone and thenpress the Send soft key.
