OVERVIEW
The Syn248 Business Phone System from AT&T is for businesses that need up to 24
extensions. This system is scalable from 1 to 8 outside lines, so as your business grows,
your phone system can too. The Syn248 Business Phone System provides simplicity
without sacrifice—it's simple to install, manage, and use, without sacrificing any of the
features you need and expect from a business telephone system.
This chapter introduces the SB35020/SB35025 Deskset and provides an overview of the
Syn248 System and the external features of the Deskset.
The SB35025 Deskset allows you to register a compatible AT&T DECT cordless headset
for hands-free phone conversations. For more information, see “Registering an Optional
Cordless Headset (SB35025 Only)” on page 86.

Syn248 System Overview
Your Deskset is part of the Syn248 System. Syn248 differs from conventional telephone
systems in that calls are not coordinated by a central controller. Instead, Syn248 uses a
distributed control system over a Local Area Network (LAN). Figure 1 illustrates a sample
system.

Deskset Overview
The SB35020 Deskset and SB35025 Deskset have identical external front-panel features,
call features, and basic settings.
The SB35025 Deskset has a built-in DECT 6.0 radio to host an optional cordless headset,
and an auxiliary in/out port for connecting a Music on Hold (MoH) source and an
overhead paging system. This User’s Guide describes how to register and use a
compatible AT&T DECT cordless headset with the SB35025 Deskset. See “Registering an
Optional Cordless Headset (SB35025 Only)” on page 86.
For more information about connecting Music on Hold and overhead paging, see

Lines and Line Keys
The system administrator can configure your Deskset with up to 8 lines on which you can
make and receive external calls. Each line is assigned to a programmable feature key on
the Deskset. These are called Line keys in this User’s Guide. One programmable feature
key is reserved for “Intercom” calls to other Deskset extensions.
Other Desksets in the system share these lines and display the line status. Incoming calls
on a line ring at all Desksets that share that line. The Line key LED indicates whether a
line is ringing, busy, or on hold.
The Line keys are used for receiving and making calls to external numbers. To call
another extension in your office, you must use an Intercom key. By default, the Intercom
key is the bottom programmable feature key, but your system administrator can
configure additional Intercom keys.

MAKING CALLS
The Deskset provides several methods for making a call. If the Deskset is idle or has calls
on hold, you can predial a phone number and then go off hook to call the number. You
can make a call at any time by choosing an off-hook method, then dialing a number. This
is referred to as Live Dialing. You can also predial or live dial using phone numbers from
lists, such as the Directory, Call Log, Redial, Quick Dial, and Messages.
You can dial the extension for the system operator by pressing 0 (zero).

Call Forward–No Answer
Call Forward–No Answer is a setting that redirects incoming calls. The Syn248 system
has two types of Call Forward–No Answer settings.
Phone Line Call Forward–No Answer can only be set by the system administrator.
This setting determines the destination for unanswered calls on each line. After a call is
forwarded, the call cannot be answered at the Deskset. Calls can be forwarded to:

an extension. Forwarded calls use the extension’s intercom line.

an extension’s voicemail (without ringing the Deskset)

an external phone number

Auto Attendant (default destination). See “About the Auto Attendant”.
ra
ft
Intercom Call Forward–No Answer is a setting unique to each Deskset. The system
administrator also sets this setting. This setting determines the delay of, and the
destination for, unanswered calls coming through your intercom line. These calls can
include intercom calls or outside calls forwarded to you by the Phone Line Call
Forward–No Answer setting. The default destination is your voicemail. It can also be set
for another extension, an outside phone number, or OFF.
About the Auto Attendant
The Syn248 system features an Auto Attendant that can answer calls during periods
when your office is closed or when calls go otherwise unanswered. The Auto Attendant
has an interactive voice menu that can guide callers to the desired extension or
extension’s voicemail.
If your Deskset is set as the Operator extension, you can set the Auto Attendant to one
of three menus: a default menu, a Day menu and a Night menu. The default menu
instructs callers to “Enter the extension number or enter 0 for the operator.” You can
customize both the Day and Night menus with your own greeting message and
instructions to callers.
Caller Options
Until callers get through to a live person, they can press 0 at any time to redirect their
call to the system operator, if the system administrator has enabled this feature.
When a caller is redirected to voicemail, the caller has the option to press 5 to skip the
greeting and press 0 to reach the operator.
The Auto Attendant may be set up so that callers can access the Auto Attendant
directory. This allows callers to use any touch-tone phone's dial pad to spell your name,
followed by pressing the pound (#) sign, to reach your extension.

Accessing Your Voicemail Remotely
Remote access allows you to listen to messages or change the recorded greeting when
you are away from your Deskset. Follow the voice prompts and press the appropriate
dial-pad keys to navigate through the system. The voice prompts in a menu list are
repeated three times with a 5-second pause between. After three times with no action,
the voice says “Goodbye” and the remote call is disconnected.
Listening to the time/date stamp information of a message does not count as listening
to the message. If you access the voicemail through remote access and skip to another
message while the time or date is playing, the message is still considered new.
To use this feature, your system must be set up for remote voicemail access. The
Phone Line Call Forward–No Answer setting and Intercom Call Forward–No
Answer setting must allow you to reach your extension’s voicemail. For more
information, consult your system administrator.
To access voicemail remotely:
Dial your company phone number.

password (if you have created one), then enter pound (#) to access the voice prompt
menu.
If you have not created a password, press the pound (#) key.
If your mailbox is full, your voicemail greeting does not play. Instead you hear
“Voicemail is full” before being disconnected. To access your voicemail when
your mailbox is full, quickly press the star key twice (* *) just as the “Voicemail
