Overview
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:

Dial plan is a string of characters that governs the way your SIP-T21P IP phone processes
the inputs received from your phone keypad. The SIP-T21P 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
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.

Hot desking originates from the definition of being the temporary physical occupant of
a work station or surface by a particular employee. A primary motivation for hot
desking is cost reduction. This feature is regularly used in places where not all the
employees are in the office at the same time, or not in the office for very long at all,
which means actual personal offices would be often vacant, consuming valuable space
and resources.
You can use hot desking on the SIP-T21P IP phone to log out of the existing accounts and
then log into a new account, that is, many users can share the phone resource in
different time. To use this feature, you need to configure a hot desking key in advance.

Hot desking is not available on all servers. Contact your system administrator for more
information.

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.

You can also configure the phone to use a default codec for sending multicast RTP
stream via web interface.
To configure a default codec for multicast paging via web user interface:
1.
Click on Features->General Information.
2.
Select the desired codec from the pull-down list of Multicast Codec.
The default codec is G722.
3.
Note
Click Confirm to accept the change.
If G722 codec is used for multicast paging, the LCD screen prompts "HD" to indicate that
the phone is providing high definition voice.
Default codec for multicast paging is configurable via web user interface only.
To send RTP stream:
1.
Press the multicast paging key when the phone is idle.
The phone sends RTP to a preconfigured multicast address (IP: Port). Any phone in
the local network then listens to the RTP on the preconfigured multicast address (IP:
Port). For both sending and receiving of the multicast RTP, there is no SIP signaling

The following figure shows a multicast RTP session on the phone:
Note
2.
Press the Hold soft key to place the current multicast RTP session on hold.
3.
Press the Cancel soft key to cancel the multicast RTP session.
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.
You can configure the phone to receive a Real Time Transport Protocol (RTP) stream from
the pre-configured multicast address(es) without involving SIP signaling. You can
specify up to 10 multicast addresses that the phone listens to on the network.
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.

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.
