Dial plan is a string of characters that governs the way your IP phone processes the inputs
received from your phone dialpad.
Yealink IP phones support the following dial plan features:
Configuring the Replace Rule

Configuring the Dial Now

Configuring the Area Code

Configuring the Block Out

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.
An "x" can be used as a placeholder for any character. Example:
x
"12x" would match "121", "122", "123", "12a", etc.
Numeric ranges are allowed within the brackets: Digit "-" Digit. Example:
-
"[5-7]" would match the number "5", "6" or "7".
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:
"([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: "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".
The IP phone supports a new dial plan mechanism – digit map. Digit maps are defined by a single
string or a list of strings. If a number you dial matches any string of a digit map, the call is
automatically placed.
Note that if digit map feature is enabled, the old dial plan rules (described in this chapter) will be
ignored. For more information, contact your system administrator.
