Note

Two ways to customize configurations of your SIP-T21(P) E2 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.

The above introduces the default LED status. The statuses of the power indicator LED and

BLF key are configurable via web user interface. For more information, refer to

Yealink_SIP-T2_Series_T4_Series_IP_Phones_Administrator_Guide.

User Guide for the SIP-T21(P) E2 IP Phone

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 19.

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

address (e.g., http://192.168.0.10 or 192.168.0.10) in the address bar of web browser on

your PC. The default administrator user name and password are both “admin”

(case-sensitive).

The options you can use to customize the IP phone via phone user interface and/or via

web user interface are listed in the following table:

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:

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:

"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

Customizing Your Phone

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.

2. Enter the string (e.g., 1) in the Prefix field.

3. Enter the string (e.g., 1234) in the Replace field.

4. Enter the desired line ID in the Account field or leave it blank.

5. Click Add to add the replace rule.

User Guide for the SIP-T21(P) E2 IP Phone

When you enter the number “1” using the keypad and then press the Send soft key,

the phone will dial out “1234” instead.

Note

2. Select one or more replace rules by checking the check box(es).

3. Click Del to delete the replace rule(s).

Note

You can configure one or more dial-now rules (up to 100) on your phone. When the

dialed number matches the dial-now string, the number will be dialed out automatically.

For example, a dial-now rule is configured as "1xx", any entered three-digit string

beginning with 1 will then be dialed out automatically on the phone.

To add a dial-now rule via web user interface:

1. Click on Settings->Dial Plan->Dial-now.

2. Enter the desired value (e.g., 1xx) in the Rule field.

3. Enter the desired line ID in the Account field or leave it blank.

The valid values of Account field can be one or two digits between 1 and 2. Each digit

must be separated by a comma. For example, when you enter the value “1, 2” in the Account field, this replace rule will apply to account1 and account2.

If you leave the Account field blank or enter 0, the replace rule will apply to all accounts. Replace rule is configurable via web user interface only.

Customizing Your Phone

For more information on the valid values of Account field, refer to Replace Rule on

page 61.

Min Length: 1, Max Length: 15". When you dial out the number "56789" (the length of the

number is between 1 and 15), the phone will add the area code and dial out the
