―12.‖ would match ―123‖, ―1234‖, ―12345‖, etc.
x
An ―x‖ can be used as a placeholder for any character. Example:

[]
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 IP phone processes
the inputs received from your phone keypad. The SIP-T20P 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 55
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 Settings->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.
45
Page 56
User Guide SIP-T20P IP Phone

If you leave the Account field blank or enter 0, the replace rule will apply to all accounts.
Replace rule is configurable via web user interface only.

three-digit string beginning with 2 will be dialed out automatically on the phone.
To add dial-now rule via web user interface:

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 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.

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.

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 Music on Hold Server account. When a call is placed on hold, the
phone will send a SIP INVITE message to the Music on Hold Server account. The Music
on Hold 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.
To configure music on hold server via web user interface:
1. Click on Account.
2. Select the desired account from the pull-down list of Account.

When you placed a call on hold, the held party can hear the music.
ACD is often used in offices for customer service, such as call center. The ACD system
handles the large volumes of incoming calls from callers who have no need to talk to a
specific person but who require assistance from any of multiple persons at the earliest
opportunity. ACD on the SIP-T20P IP phone allows the ACD system to distribute large
volumes of incoming calls to the registered ACD users. To use this feature, you should
configure an ACD key in advance.
To configure an ACD key via phone user interface:
1. Press .
2. Select Features->DSS Keys.
