User Interfaces
Two ways to customize configurations of your SIP-T42S 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.
Phone User Interface
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

Note
Power over Ethernet
With the included or a regular Ethernet cable, the SIP-T42S IP phone can be powered from a
PoE-compliant switch or hub.
15
User Guide for the SIP-T42S IP Phone
If in-line power is provided, you don’t need to connect the phone to the power adapter. Make
sure the switch/hub is PoE-compliant.
The phone can also share the network with another network device such as a PC (personal
computer). This is an optional connection. We recommend that you use the Ethernet cable
provided by Yealink. The PC port may be disabled, contact your system administrator for more
information.
Important! Do not remove power from the phone while it is updating firmware and
configurations.
If your network does not use DHCP, proceed to Basic Network Settings on page 18.
To connect the PoE:
1. Connect the Ethernet cable between the Internet port on the phone and an available port
on the in-line power switch/hub.
Note
Phone Initialization
After your phone is powered on, the system boots up and performs the following steps:

.
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.
-
Numeric ranges are allowed within the brackets: Digit “-” Digit. Example:
Multiple Line Keys per Account
You can configure multiple line keys to associate with an account. This enhances call
visualization and simplifies call handling.
If this is the case, the LCD screen will resemble the following figure:
Incoming calls to this account will be distributed evenly among the available line keys. Outgoing
calls will be distributed similarly.
Your phone can be configured to have a combination of accounts with a single line key and
accounts with multiple line keys.
Dial Plan
Dial plan is a string of characters that governs the way your SIP-T42S IP phone processes the
inputs received from your phone keypad.
The SIP-T42S IP phone supports the following dial plan features:
Replace Rule
Dial Now
Area Code
Block Out
The basic expression syntax you need to know:
68
“[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 “$” followed by the sequence number of a parenthesis means the
characters placed in the parenthesis. The sequence number stands for the
corresponding parenthesis. 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”.
Note
The IP phone supports a new dial plan mechanism – digit map. Digit maps are defined by a single
string or a list of strings. If a number you dial matches any string of a digit map, the call is
automatically placed.
Note that if digit map feature is enabled, the old dial plan rules (described in this chapter) will be
ignored. For more information, contact your system administrator.
Customizing Your Phone
Replace Rule
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: 1234”, when you try 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:
