Overview
Two ways to customize configurations of your SIP-T21P/SIP-T21 IP phone:
The user interface on the IP phone.
The user interface in a web browser on your PC.
The hardware components keypad and LCD screen constitute the phone user interface,
which allows the user to execute all call operation tasks and basic configuration
changes directly on the phone. In addition, you can use the web user interface to
access all configuration settings. In many cases, either the phone user interface and/or
the web user interface interchangeably. However, in some cases, it is only possible to
use one or the other interface to operate the phone and change settings.
You can customize your phone by pressing the Menu soft key to access the phone user
interface. The Advanced Settings option is only accessible to the administrator, and the
default administrator password is “admin” (case-sensitive). For more information on
customizing your phone with the available options from the phone user interface, refer
to Customizing Your Phone on page 17.
In addition to the phone user interface, you can also customize your phone via web user
interface. In order to access the web user interface, you need to know the IP address of
your new phone. To obtain the IP address, press the OK key on the phone. Enter the IP

.
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: "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”.
Incoming calls to this account will be distributed evenly among the available line keys.
Outgoing calls will be distributed similarly.
Dial plan is a string of characters that governs the way your SIP-T21P/SIP-T21 IP phone

The basic expression syntax you need to know:
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: 1” and “Replace: 1234567”. When
trying to dial out the number “1234567”, you just need to enter “1” on the phone and
then press the Send soft key.
