You need to know the following basic regular expression syntax when creating dial
plan:
.
The dot “.” can be used as a placeholder or multiple placeholders for
any string. Example:
“12.” would match “123”, “1234”, “12345”, “12abc”, etc.
x
The “x” can be used as a placeholder for any character. Example:
“12x” would match “121”, “122”, “123”, “12a”, etc.
-
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”, etc.
$
The “$” followed by the sequence number of a parenthesis means
the characters placed in the parenthesis. 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 IP
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 is an alternative string that replaces the numbers entered by the user. IP
phones support up to 100 replace rules, which can be created either one by one or in
batch using a replace rule template. For more information on how to customize a
replace rule template, refer to
