Two ways to customize configurations of your SIP-T20P/SIP-T20 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, each phone has a 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 key to access the phone user
interface. The Advanced 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:

[]
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‖.

Dial plan is a string of characters that governs the way your SIP-T20P/SIP-T20 IP phone
processes the inputs received from your phone keypad. The SIP-T20P/SIP-T20 IP phone
supports the following dial plan features:
Replace Rule
Dial-now
Area Code
Block Out
The basic expression syntax you need to know:
44
Page 57
Customizing Your Phone
―91([5-7])1(x)‖ would match ―91511‖, ―91618‖, ―91715‖.
$
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‖.
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 (refer to
the expression syntax in 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 OK key to dial out.
To add a replace rule via web user interface:
1. Click on Set tings->Dial Plan->Replace Rule.
2. Enter the string (e.g., 1) in the Prefix field.
3. Enter the string (e.g., 1234) in the Replace field.
4. Enter the desired line ID in the Account field or leave it blank.

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-T20P/SIP-T20 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

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 is the highest priority, 10 is 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.
To configure multicast listening addresses via web user interface:
1. Click on Directory->Multicast IP.
2. Select the desired value from the pull-down list of Paging Barge.
