Basic Regular Expression Syntax for Four Patterns
You need to know the following basic regular expression syntax when creating an old dial plan:
Regular
expression
Description
.
The dot “.” can be used as a placeholder or multiple placeholders for any string. Example:
“12.” would match “123”, “1234”, “12345”, “12abc”, and so on.
x
The “x” can be used as a placeholder for any character. Example:
“12x” would match “121”, “122”, “123”, “12a”, and so on.
-
The dash “-” can be used to match a range of characters within the brackets. Example:
“[5-7]” would match the number “5”, ”6” or ”7”.
,
The comma “,” can be used as a separator within the bracket. Example:
“[2,5,8]” would match the number ”2”, “5” or “8”.
[]
The square bracket "[]" 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 parenthesis "( )" can be used to group together patterns, for instance, to logically combine two or
more patterns. Example:
"([1-9])([2-7])3" would match “923”, “153”, “673”, and so on.
$
The “$” followed by the sequence number of a parenthesis means the characters placed in the par-
enthesis. The sequence number stands for the corresponding parenthesis. Example:
A replace rule configuration, Prefix: "001(xxx)45(xx)", Replace: "9001$145$2". When you dial out
"0012354599" on your phone, the phone will replace the number with "90012354599". “$1” means 3
digits in the first parenthesis, that is, “235”. “$2” means 2 digits in the second parenthesis, that is, “99”.
Replace Rule File Customization
The replace rule file helps create multiple replace rules. At most 100 replace rules can be added to the IP phone. It
is not applicable to T19(P) E2 phones.
You can ask the distributor or Yealink FAE for the replace rule file template. You can also obtain the replace rule file
template online:
