Customizing Your Phone

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

processes the inputs received from your phone keypad. The SIP-T21P/SIP-T21 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.

[]

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”.

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.
