Two ways to customize configurations of your SIP-T21P 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.
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 17.
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:

which means actual personal offices would be often vacant, consuming valuable space
and resources.

You can use multicast paging to quickly and easily forward time sensitive
announcements out to people within the multicast group. You can configure a multicast
paging key on the phone, which allows you to send a Real Time Transport Protocol (RTP)
stream to the pre-configured multicast address(es) without involving SIP signaling. You
can configure the phone to receive an RTP stream from pre-configured multicast
listening address(es) without involving SIP signaling. You can specify up to 10 multicast
listening addresses.

How the phone handles incoming multicast paging calls depends on Paging Barge and
Paging Priority Active parameters configured via web user interface.
Paging Barge
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. If Disabled is selected from the pull-down list of Paging Barge,
the voice call in progress takes precedence over all incoming multicast paging calls.
Valid values in the Paging Barge field:
1 to 10: Define the priority of an active call, 1 with the highest priority, 10 with the
lowest.
Disabled: The voice call in progress shall take precedence over all incoming
paging calls.
Paging Priority Active
Paging priority active parameter decides how the phone handles the 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.
Multicast RTP is one way only
from sender to the multicast address(es) (receiver). For
outgoing RTP multicasts, all other existing calls on the phone will be placed on hold.

Music on hold (MoH) is the business practice of playing recorded music to fill the silence
that would be heard by the party placed on hold. To use this feature, you should specify
a SIP URI pointing to a MoH server account. When a call is placed on hold, the phone
will send a SIP INVITE message to the MoH server account. The MoH server account
automatically answers to the SIP INVITE messages and immediately plays audio from
some source located anywhere (LAN, Internet) to the held party. Contact your system
administrator for the SIP URI.
The priorities of listening addresses are predefined: 1
with
the highest priority, 10 with the
lowest.
Both the multicast paging sender and the receiver play a warning tone when pressing
the multicast paging key.
