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

Dial plan is a string of characters that governs the way your SIP-T21(P) E2 IP phone
processes the inputs received from your phone keypad. The SIP-T21(P) E2 IP phone
supports the following dial plan features:
Replace Rule
Dial-now
Area Code
Block Out
The basic expression syntax you need to know:
67
User Guide for the SIP-T21(P) E2 IP Phone
-
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”.
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: 1234”. When trying to
dial out the number “1234”, 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.
