Yealink SIP-T20P User Manual

Customizing Your Phone
39
Dial plan is a string of characters that governs the way your SIP-T20P IP phone processes
the inputs received from your phone keypad. The SIP-T20P IP phone supports the
following dial plan features:
 Replace Rule
 Dial-now
 Area Code
 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‖, etc.
x
An ―x‖ can be used as a placeholder for any character. Example:
―12x‖ would match ―121‖, ―122‖, ―123‖, etc.
[]
The square brackets ―[]‖can be used as a placeholder for a single character
which matches any of a set of characters. Example:
―91[3-8][0-9]1234‖ would match ―91301234‖, ―91591234‖, ―91851234‖, etc.
()
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: Number: "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‖.
Note
You can configure one or more replace rules 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 ―Number: 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 OK key
You can configure the dial plan rules via web user interface only.
