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
7
User Guide for the SIP-T42S IP Phone
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
phone with the available options from the phone user interface, refer to Customizing Your
Phone on page 33.
Note
For a better understanding of the menu structure, please refer to Appendix B – Menu Structure
on page 187.
Web User Interface
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 when the phone is idle.
Enter the IP address (e.g., http://192.168.0.10 or 192.168.0.10 for IPv4;
http://[2005:1:1:1:215:65ff:fe64:6e0a] or [2005:1:1:1:215:65ff:fe64:6e0a] for IPv6) in the address
bar of a web browser on your PC. The default administrator user name and password are both
“admin” (case-sensitive).
Note
The access to the Advanced settings of the Account or Network via web user interface may be
blocked by the web browser (e.g., Chrome, Firebox) if you have installed “Adblock Plus plugin”.
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:

Customizing Your Phone
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.

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.

Advanced Phone Features
Multicast Paging
You can use multicast paging to quickly and easily broadcast time sensitive announcements to
users who are listening to a specific multicast group and a specific channel. You can configure a
multicast paging key or the paging list key on the phone, which allows you to send a Real Time
Transport Protocol (RTP) stream to the pre-configured multicast address(es) and channel(s)
without involving SIP signaling. You can configure the phone to receive an RTP stream from
pre-configured multicast listening address(es) and channel(s) without involving SIP signaling.
You can specify up to 31 multicast listening addresses and channels.
The following describes 31 paging channels:

0: You can broadcast audio to channel 0. Note that the Yealink IP phones running old
firmware version (old paging mechanism) can be regarded as listening to channel 0. It is
the default channel.

1 to 25: You can broadcast audio to a specific channel. We recommend that you specify
these channels when broadcasting with Polycom IP phones which have 25 channels you
can listen to.

26 to 30: You can broadcast audio to a specific channel. We recommend that you specify
these channels when broadcasting with Yealink IP phones running new firmware version
(new paging mechanism).
The IP phones will automatically ignore all incoming multicast paging calls on the different
channel.

Receiving RTP Stream
You can configure the phone to receive a Real Time Transport Protocol (RTP) stream from the
pre-configured multicast address(es) and channel(s) without involving SIP signaling. You can
specify up to 31 multicast addresses and channels that the phone listens to on the network.
RTP stream is listened in the hands-free (speakerphone) mode by default. If you want to listen the
RTP stream using the engaged audio device (speakerphone, handset or headset), contact your
system administrator for more information.
Note
Fixed volume to play RTP stream for specified paging group is configurable by your system
administrator.
How the phone handles incoming multicast paging calls depends on Paging Barge, Ignore DND
and Paging Priority Active parameters configured via web user interface.
Paging Barge
The paging barge parameter defines the priority of the voice call in progress. If the priority of an
incoming multicast paging call is lower than that of the active call, it will be ignored
automatically. Valid values in the Paging Barge field:

1 to 31: Define the priority of the active call, 1 with the highest priority, 31 with the lowest.

Disabled: The voice call in progress will take precedence over all incoming paging calls.
Ignore DND
The ignore DND parameter defines the lowest priority of multicast listening address from which
the phone can receive an RTP stream when DND is activated. If a priority is selected from the
pull-down list of Ignore DND, the phone will ignore incoming multicast paging calls with lower
priorities when DND is activated in phone mode. Valid values in the Ignore DND field:

1 to 31: Define the lowest priority of the multicast listening address from which the phone
can receive an RTP stream, 1 with the highest priority, 31 with the lowest.

Disabled: All the incoming multicast paging calls will be ignored when DND is activated in
phone mode.
The phone will automatically answer all incoming multicast paging calls when DND is activated
in custom mode.
154
Advanced Phone Features
Paging Priority Active
The paging priority active parameter decides how the phone handles incoming multicast paging
calls when there is already a multicast paging call on the phone. If enabled, the phone will
ignore incoming multicast paging calls with lower priorities, otherwise, the phone will answer
incoming multicast paging calls automatically and place the previous multicast paging call on
hold. If disabled, the phone will automatically ignore all incoming multicast paging calls.
To configure multicast listening addresses via web user interface:
1.
