The SIP-T46G IP phone supports thefollowing dial plan features: Replace Rule Dial-now Area Code Block OutThe basic expression syntax 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: Number: "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”.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 (expression syntaxrefer to 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 "Prefix: 1" and "Replace: 1234567", when you try to dial out the number“1234567”, you just need to enter “1” on the phone and then press the Send soft key.You can configure the dial plan rules via web user interface only.
