VERVIEW

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

Figure 1. Sample Syn248 System

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 input/output 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
the Syn248 Installation and Configuration Guide, available from

smbtelephones.att.com.

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.

Setting Your Password

You can protect your Deskset by setting a password that prevents other users from
accessing your User Settings and messages. If you create a password, you will need to
enter it before accessing User Settings, messages, and the WebUI.

For more information, see “Setting, Changing, or Resetting Your Password” on page 85.

Answer

Ignoring a Call

You can ignore an incoming call by pressing to silence the ringer. The silenced
ringer icon appears. If you are on an active or held call, after the incoming call has been
ignored, the screen returns to the call you were on before the incoming call.

 Once a call is ignored:

 The key is no longer available on the incoming call screen.

 The Line key continues to flash. If it is an intercom call, the Intercom key

flashes.

 You can press the key or the flashing Line or Intercom key to

answer the incoming call.

 Going off hook—lifting the handset, pressing (SPEAKER), or pressing

(HEADSET)—does not answer the call. Going off hook starts a new call

on the next available line.

 If no one answers the call, the call goes to the Call Forward–No Answer

destination. The default destination for external calls is the Auto Attendant.
The default destination for intercom calls is voicemail. See “Call Forward–No

Answer” on page 32.

Your system administrator can set your Deskset to ignore incoming calls on
selected lines. If your Deskset has one or more lines configured this way, your
Deskset automatically ignores incoming calls on those lines. Your Deskset does
not ring, but you can answer the call by pressing the key or the flashing
Line key.

Intercom Auto Answering

You can set your Deskset to answer intercom calls automatically, without your having to
touch the phone to answer. When you enable Intercom Auto Answer, ANS appears at
the top of the Deskset screen as shown in Figure 13 unless DND is active, since Auto
Answer is disabled when DND is on.

Intercom Auto Answering applies only to direct Deskset-to-Deskset calls. Auto
Answering does not apply to forwarded calls that use your intercom line(s).

Figure 13. Intercom Auto Answer Enabled

To respond to an Auto Answered intercom call:

After the call rings for the amount of time specified in the Auto Answer Delay (see

“Intercom Auto Answer” on page 79), a two-second notification screen appears, and you

hear a warning tone. Speak after the tone.

If the Intercom Auto Answer Delay is set to zero, you hear no ring. Instead, the

Call Answered screen appears and you hear the warning tone.

If you do not want the Deskset to automatically answer the call, press (CANCEL) or

while the call is ringing to send the call to the Intercom Call Forward–No

Answer target. See “Call Forward–No Answer” on page 32.

If there are multiple incoming intercom calls, Auto Answer applies to the first call.

Answering Calls 31

Syn248 SB35020/SB35025 Deskset User’s Guide Back to Contents

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”.

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.” The system
administrator can customize both the Day and Night menus with your own company’s
greeting message and instructions to callers. For more information, see “Auto-Attendant

Settings” on page 90.

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.
