Via web user interface
The phone user interface, being made up of keypad and LCD screen, allows users to perform all
call operations and change basic configuration settings directly on the phone. But if you want to
access all configuration settings, you should use web user interface instead. In most cases, it is
possible to configure your IP phone via both phone user interface and web user interface. While
in some particular cases, only via phone user interface or via web user interface is available for
you to operate or configure your IP phone. This guide mainly takes phone user interface as an
example.

Dial Plan
Dial plan is a string of characters that governs the way your IP phone processes the inputs
received from your phone dialpad.
Yealink IP phones support the following dial plan features:
Configuring the Replace Rule
Configuring the Dial Now
Configuring the Area Code
Configuring the Block Out
The basic expression syntax you need to know:
.
The dot "." can be used as a placeholder or multiple placeholders for any
character. Example:
"12." would match "123", "1234", "12345", "12abc", etc.
x
An "x" can be used as a placeholder for any character. Example:
"12x" would match "121", "122", "123", "12a", etc.
-
Numeric ranges are allowed within the brackets: Digit “-” Digit. Example:
“[5-7]” would match the number ”5”, ”6” or ”7”.
[]
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:
"([1-9])([2-7])3" would match "923", "153", "773", etc.
$
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: "001(xxx)45(xx)", Replace: "9001$145$2".
When you dial out "0012354599" on your phone, the IP phone will replace the
number with "90012354599". “$1” means 3 digits in the first parenthesis, that
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.
Customizing Your Phone
105
Configuring the Replace Rule
Configuring a replace rule can speed up the pace of dialing out a long number. You can
configure up to 100 replace rules, a pattern(s) with wildcards (refer to the expression syntax in
the table above), so that any string that matches the pattern(s) will be replaced. 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.
Adding a Replace Rule

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. Up to 31
multicast addresses and channels that the phone listens to on the network can be configured.
Note
How the phone handles incoming multicast paging calls depends on Paging Barge, Ignore DND
and Paging Priority Active configured via web user interface.
Paging Barge
Paging Barge feature defines the lowest priority of the multicast listening address from which
the phone can receive an RTP stream when there is a voice call (a normal phone call rather than
a multicast paging call) in progress. If it is disabled, all incoming multicast paging calls will be
automatically ignored. If it is set to a specify priority value, the incoming multicast paging calls
with higher or equal priority are automatically answered and the ones with lower priority are
ignored. Valid values for Paging Barge:
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: The voice call in progress will take precedence over all incoming paging calls.
RTP stream is listened in the hands-free (speakerphone) mode by default. If you want to listen the
RTP stream using other engaged audio devices (speakerphone, handset or headset), contact your
system administrator for more information.
Fixed volume to play RTP stream for specified paging group is configurable by your system
administrator.
Advanced Phone Features
183
Ignore DND
Ignore DND feature 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 for Ignore DND:
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.
Paging Priority Active
Paging Priority Active feature 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.

This feature is very useful in the boss and secretary scenario. For example, the boss shares his
extension with the secretary. When there is an incoming call to the extension of the boss, both
the phones of the boss and the secretary will ring simultaneously, and either the boss or the
secretary can answer the call. Calls on the shared line can be placed on hold, barged in or
retrieved from another shared phone.
It is recommended that you configure only one ACD key per phone, since only one ACD key can
be in use on your phone at any time.

4603 (register name and user name are 4603) and assigns line key 1 and line key 2 for the
account 4603, secretary phone registers the alternate account 4603_1 (register name is 4603,
user name is 4603_1) and assigns line key 1 and line key 2 for the account 4603_1, third party
phone registers the account 4604. For more information on how to register an account, refer to
