About This Guide
Thank you for choosing the SIP-T21 E2/SIP-T21P E2 (hereinafter referred to as SIP-T21(P) E2) IP
phone, exquisitely designed to provide business telephony features, such as Call Hold, Call
Transfer, Busy Lamp Field, Multicast Paging and Conference over an IP network. The difference
between the SIP-T21 E2 and SIP-T21P E2 IP phones is that only SIP-T21P E2 supports PoE.
This guide provides everything you need to quickly use your new phone. First, verify with your
system administrator that the IP network is ready for phone configuration. Also be sure to read
the Packaging Contents in this guide before you set up and use the SIP-T21(P) E2 IP phone.

The above introduces the default LED status. The statuses of the power indicator LED and BLF key

__rendered_path__33
BLF key behavior. For more information, contact your system administrator.

User Interfaces
__rendered_path__34
Two ways to customize configurations of your SIP-T21(P) E2 IP phone:

your PC.
__rendered_path__43
The hardware components keypad and LCD screen constitute the phone user interface, which
__rendered_path__43
allows the user to execute all call operation tasks and basic configuration changes directly on
__rendered_path__32
the phone. In addition, you can use the web user interface to access all configuration settings. In
__rendered_path__33
many cases, either the phone user interface and/or the web user interface interchangeably.
__rendered_path__32
However, in some cases, it is only possible to use one or the other interface to operate the
__rendered_path__34
phone and change settings.
__rendered_path__32
Phone User Interface
__rendered_path__53
You can customize your phone by pressing the Menu soft key to access the phone user
__rendered_path__53
interface. The Advanced Settings option is only accessible to the administrator, and the default
__rendered_path__53
administrator password is admin (case-sensitive). For more information on customizing your
__rendered_path__32
phone with the available options from the phone user interface, refer to Customizing Your
__rendered_path__33
Phone on page 35.

Web User Interface
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 when the phone is idle.
Enter the IP address (e.g., http://192.168.0.10 or 192.168.0.10 for IPv4;
http://[2005:1:1:1:215:65ff:fe64:6e0a] or [2005:1:1:1:215:65ff:fe64:6e0a] for IPv6) in the address
bar of a web browser on your PC. The default administrator user name and password are both
admin (case-sensitive).
Note
The access to the Advanced settings of the Account or Network via web user interface may be
Image_543_0
blocked by the web browser (e.g., Chrome, Firebox) if you have installed “Adblock Plus plugin”.

To connect the PoE for the SIP-T21P E2 IP phone:
1.
Connect the Ethernet cable between the Internet port on the phone and an available port
on the in-line power switch/hub.
Image_591_0
If in-line power is provided, you don’t need to connect the phone to the power adapter. Make
Image_596_0
sure the switch/hub is PoE-compliant.
The phone can also share the network with another network device such as a PC (personal
computer). This is an optional connection. We recommend that you use the Ethernet cable
provided by Yealink. The PC port may be disabled, contact your system administrator for more
information.
Important! Do not remove power from the phone while it is updating firmware and
configurations.
__rendered_path__92
After your phone is powered on, the system boots up and performs the following steps:
Automatic Phone Initialization
The phone finishes the initialization by loading the saved configuration. The LCD screen displays
Welcome Initializing…please wait” during this process.
DHCP (Dynamic Host Configuration Protocol)
The phone attempts to contact a DHCP server in your network to obtain valid IPv4 network
settings (e.g., IP address, subnet mask, default gateway address and DNS address) by default.
Image_594_0
If your network does not use DHCP, proceed to Basic Network Settings on page 30.

Example:
__rendered_path__57
-
Numeric ranges are allowed within the brackets: Digit “-” Digit. Example:
__rendered_path__55
“[5-7]” would match the number”5”, ”6”or ”7”.
__rendered_path__55
The square brackets "[]" can be used as a placeholder for a single character
__rendered_path__58
[]
which matches any of a set of characters. Example:
__rendered_path__58
"91[5-7]1234" would match "9151234", "9161234", "9171234".
__rendered_path__58
The parentheses "( )" can be used to group together patterns, for instance, to
__rendered_path__55
()
logically combine two or more patterns. Example:
__rendered_path__56
"([1-9])([2-7])3" would match "923", "153", "773", etc.
__rendered_path__55
The “$” should be followed by the sequence number of a parenthesis. The “$”
__rendered_path__57
plus the sequence number means the whole character or characters placed in
__rendered_path__55
the parenthesis. The number directs to the right parenthesis when there are
__rendered_path__95
$
more than one. Example:
A replace rule configuration, Prefix: "001(xxx)45(xx)", Replace: "9001$145$2".
__rendered_path__95
When you dial out "0012354599" on your phone, the IP phone will replace the
__rendered_path__95
number with "90012354599". “$1” means 3 digits in the first parenthesis, that
__rendered_path__55
is, “235”. “$2” means 2 digits in the second parenthesis, that is, “99”.
__rendered_path__56
Note
The IP phone supports a new dial plan mechanism digit map. Digit maps are defined by a single
__rendered_path__55
string or a list of strings. If a number you dial matches any string of a digit map, the call is
__rendered_path__57
automatically placed.
__rendered_path__55
Note that if digit map feature is enabled, the old dial plan rules (described in this chapter) will be
__rendered_path__113

__rendered_path__113
You can configure one or more replace rules (up to 100) to remove the specified string and
__rendered_path__55
replace it with another string. You can configure a pattern with wildcards (refer to the expression
__rendered_path__56
syntax in the table above), so that any string that matches the pattern will be replaced. This

Public telephone networks in countries around the world have a single emergency telephone
number (emergency services number), that allows a caller to contact local emergency services
for assistance when necessary. The emergency telephone number may differ from country to
country. It is typically a three-digit number so that it can be easily remembered and dialed
quickly. Some countries have a different emergency number for each of the different emergency
services.
You can specify the emergency telephone numbers on the IP phone for contacting the
emergency services in an emergency situation. You can dial these numbers when the phone is
locked. For more information on phone lock, refer to Phone Lock on page 43.

the server when a certain action takes place. For example, if you set the Always Forward on code
to be *71 (may vary on different servers), and the target number to be 1234. When you activate
Always Forward on the IP phone, the IP phone sends *711234 to the server, and then the server
will activate Always Forward feature on the server side, hence being able to get the right status
of the extension.

Hot desking originates from the definition of being the temporary physical occupant of a work
__rendered_path__32
station or surface by a particular employee. A primary motivation for hot desking is cost
__rendered_path__30
reduction. This feature is regularly used in places where not all the employees are in the office at
__rendered_path__33Image_1293_0
the same time, or not in the office for very long, which means that actual personal offices would
__rendered_path__33
be often vacant, consuming valuable space and resources.

Multicast Paging
You can use multicast paging to quickly and easily broadcast time sensitive announcements to
users who are listening to a specific multicast group and a specific channel. You can configure
the paging list key on the phone, which allows you to send a Real Time Transport Protocol (RTP)
stream to the pre-configured multicast address(es) and channel(s) without involving SIP
signaling. You can configure the phone to receive an RTP stream from pre-configured multicast
listening address(es) and channel(s) without involving SIP signaling. You can specify up to 31
multicast listening addresses and channels.
The following describes 31 paging channels:
0
: You can broadcast audio to channel 0. Note that the Yealink IP phones running old
firmware version (old paging mechanism) can be regarded as listening to channel 0. It is
the default channel.
1 to 25
: You can broadcast audio to a specific channel. We recommend that you specify
these channels when broadcasting with Polycom IP phones which have 25 channels you
can listen to.
26 to 30
:
You can broadcast audio to a specific channel. We recommend that you specify
these channels when broadcasting with Yealink IP phones running new firmware version
(new paging mechanism).
The IP phones will automatically ignore all incoming multicast paging calls on the different
channel.

How the phone handles incoming multicast paging calls depends on Paging Barge, Ignore DND
and Paging Priority Active parameters configured via web user interface.
Paging Barge
The 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. Valid values in the Paging Barge field:
1 to
31
: Define the priority of the active call, 1 with
the highest priority, 31
with the lowest.
Disabled
: The voice call in progress will take precedence
over all incoming paging calls.
Ignore DND
The ignore DND parameter 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 in the Ignore DND field:
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
The paging priority active parameter 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.
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.
3. Select the desired value from the pull-down list of Ignore DND.
4. Select the desired value from the pull-down list of Paging Priority Active.
5. Enter the multicast IP address(es) and port number (e.g., 224.5.6.20:10008) which the phone
listens to for incoming RTP multicast in the Listening Address field.
6. (Optional.) Enter the label in the Label field.
Label will appear on the LCD screen when receiving the multicast RTP stream.
7. Select the desired channel to listen from the pull-down list of Channel.

Music on Hold (MoH)
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 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.
Note
If your server supports the MOH feature, you can also upload the custom music file into it

ACD is often used in offices for customer service, such as call center. The ACD system handles
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-T21(P) E2 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.
Make sure ACD is enabled on your IP phone. For more information on enabling ACD, contact your

Shared Call Appearance (SCA)
You can use SCA feature to share an extension which can be registered on two or more IP
phones at the same time. The shared line is indicated by a different line icon.
In the following figure, the first line is private and the second line is shared:
Image_1360_0
__rendered_path__83
If two phones share a line, an incoming call to this extension will cause both phones to ring
simultaneously. The incoming call can be answered on either phone but not both.
This feature is very useful in the boss and secretary scenario. For example, the secretary can
share the boss's extension on her phone. When there is an incoming call to the extension of the
boss, both the phones of the boss and the secretary will ring simultaneously. 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.
Configuring SCA Feature on the IP Phone
You can configure a primary account on the IP phone and other alternate accounts on the other
IP phones. In a SCA Hybrid Key System scenario, you can automatically assign multiple DSS keys
with Line type for a registered shared line on the phone (If auto linekeys feature is enabled). For
example, party A, party B share the account 4603, phone A registers the primary account 4603
and assigns line key 1 and line key 2 for the account 4603, phone B registers the alternate
account 4603_1 and assigns line key 1 and line key 2 for the account 4603_1, phone C registers
the account 4604.
