Overview

Note

Two ways to customize configurations of your SIP-T42G 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, it is possible to use 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.

Syntax

Description

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", etc.

()

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: "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”.

Dial plan is a string of characters that governs the way your SIP-T42G IP phone

processes the inputs received from your phone keypad. The SIP-T42G IP phone supports

the following dial plan features:

 Replace Rule

 Dial-now

 Area Code

 Block Out

Basic expression syntaxes 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

(expression syntax refer to 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 you try

to dial out the number “1234567”, you just need to enter “1” on the phone and then

press the Send soft key.

User Guide for the SIP-T42G IP Phone

Valid values of Account field can be one or more digits among 1, 2, and 3. Every two digits 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 account 1 and account 2.

beginning with 2 will 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.
