The basic expression syntax you need to know:
.
The dot ”.” can be used as a placeholder or multiple placeholders for any
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 single character
which matches any of a set of characters. Example:
“91[5-7]1234” would match “9151234”, “9161234”, “9171234”.
()
The parentheses “( ) “can be used to group together patterns, for instance, to
logically 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 characters
placed in the parenthesis. The number directs to the right parenthesis when
there are more than one. 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”.
You can configure one or more replace rules (up to 100) to remove the specified string
and replace it with another string. You can configure a pattern with wildcards (refer to
the expression syntax 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 rule is configured as “Prefix: 00” and “Replace: 123456”, when you
try to dial out the number “123456”, you just need to enter “00” on the phone and then
press the Send soft key.
To add a replace rule via web user interface:
1. Click on Settings->Dial Plan->Replace Rule.
2. Enter the string (e.g., 00) in the Prefix field.
3. Enter the string (e.g., 123456) in the Replace field.
