User Guide for the T48S Skype for Business phone

as any one of the team members picks up the phone, the other phones stop ringing.

Response Groups
If you sign into the phone using On-Premises account, you can use response group feature. But

A response group is a feature that route and queue incoming calls to group members, called
agents, such as to a help desk or a customer service desk.
When someone calls a response group, the call is routed to an agent based on a hunt group or
the caller's answers to interactive voice response (IVR) questions. The Response Group
application uses standard response group routing methods to route the call to the next
available agent. After a call agent accepts the call, other agents’ phones stop ringing.
For example, you have been selected by your system administrator to be a call agent for a
response group named “YEALINK”. When a user named “yl30” calls your response group, your
phone is shown as below:
Note

agents, such as to a help desk or a customer service desk.
When someone calls in to a phone number that is set with a call queue, they will hear a
greeting first (if any is setup), and then they will be put in the queue and wait for the available
call agent. The person calling in will hear music while they are placed on hold and waiting, and
the call in the queue will ring all call agents at the same time. After a call agent accepts the call,
other agents’ phones stop ringing.
Note
Inbound Private Line
If you sign into the phone using On-Premises account, you can use inbound private line
feature. But the current Online environment does not support this feature.
In many organizations, the administrative secretary may answer the office phones for his boss
sometimes. This is easily accomplished on the Skype for Business Server by using call
delegation. As a result, if one person dials the primary line of the boss, the phones of the
delegates will ring simultaneously.
Call queue can be configured on Server only. Contact your system administrator for more
information.
Basic Call Features
115
The system administrator can assign a private line to boss if one of the following situations
occurs:
The boss doesn’t want to miss important calls denied by his DND status.
The boss doesn’t want the delegate to answer some important or confidential calls for
him.
The boss wishes his friends and families to reach him directly or bypass his delegate.
So compared with dialing the primary line of the boss, if the people dial the private line of the
boss, only boss’s phone rings.
Characteristics of Private Lines:
A user can have only one private line.
A user with a private line has only one voicemail.
The phone receives the calls calling to the private line rings at any time. They do not
follow "Do Not Disturb" rules.
Private lines are inbound only and cannot be used to make outgoing calls.
None of the following features are available with a private telephone line: delegation, and
Response Group application.
For more information on planning for private telephone lines, refer to
Plan for private
telephone lines
.
When receiving a private call, the touch screen of the phone will prompt “Call for private line”:

Receiving RTP Stream
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
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. If Disabled is selected from the pull-down list of Paging Barge, the voice call in
progress will take precedence over all incoming multicast paging calls. Valid values in the
Paging Barge field:
1 to 10: Define the priority of the active call, 1 is with the highest priority, while 10 is with
the lowest.
Disabled: The voice call in progress will take precedence over all incoming paging calls.
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.

Common Area Phone
Common area phones are those Skype for Business phones that are not associated with an
individual user. Instead of being deployed in someone’s office, common area phones are
typically deployed in building lobbies, cafeterias, employee lounges, conference rooms, and
other places where a large number of people are likely to gather. Unlike other phones on the
Skype for Business Server, which are typically maintained by voice policies and dial plans that
are assigned to individual users, common area phones do not have individual users assigned to
them.
This chapter explains how to use the Common Area Phone. Topics include:
