Basic expression syntaxes you need to know:
Syntax Description
.
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", etc.
()
The parentheses "( )" 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", "773",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: "9([5-7])(.)", Replace: "5$2". When
you enter "96123" to dial out on your phone, the number will be
replaced as "5123" and then dialed out. “$2” means the characters in
the second parenthesis, that is, “123”.

You can configure one or more replace rules (at most 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: 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.
To add a replace rule via web user interface:
1. Click on Settings->Dial Plan->Replace Rule.
2. Enter the string (e.g., 2xx) in the Prefix field.
3. Enter the string (e.g., 12345) in the Replace field.
