This AT&T MS2085 is the console of a 4-line telephone system. It is expandable to a maximum of 15 AT&T MS2015 desksets and an AT&T TL7600 cordless headset. Expanding your system requires you to register each new device first (see pages 20-21). This system is not compatible with any other AT&T 4-line small business telephones, except for the MS2015 telephone.

The MS2085 telephone is hearing-aid compatible and can be connected to four telephone lines. This telephone features a speakerphone for handsfree use and a headset jack compatible with most headsets using two-band

2.5mm headset plugs (sold separately).

There are two network jacks, known as the Ethernet jack and PC jack, at the back of the console. The Ethernet jack allows the MS2085 telephone to connect with MS2015 desksets via a router. The PC jack is for another device such as a personal computer to connect to the Ethernet network through the console.

The MS2085 console supports intercom and call transfers between system extensions and is capable of connecting five parties on the same conference call.

This telephone also features a 32-number one- and two-touch memory for faster dialing and has a directory that can store up to 50 additional numbers with names. This telephone has a caller ID feature that supports caller ID with call waiting service. Caller ID services are subscriber services available from many telephone service providers for a fee. The telephone can store up to 200 caller ID entries.

Your MS2085 console also features a built-in digital answering system with a central mailbox and private mailbox. This MS2085 telephone is equipped to function as an auto attendant in a multi-telephone system. An auto attendant telephone can pick up and redirect incoming calls to other extensions in your telephone system. For details, see the Auto attendant operation section (pages 89-90). This user’s manual contains detailed instructions for using your MS2085 console. Please read this user’s manual before using this telephone.

Getting started

Introduction

The MS2085 package includes only the console. You have to purchase MS2015 deskset/TL7600 cordless headset separately to expand your system.

To order them, visit our website at www.telephones.att.com or call

1 (800) 222-3111. In Canada, dial 1 (866) 288-4268.

You must install and setup the MS2085 console first before expanding your system with MS2015 deskset/TL7600 cordless headset. Make sure your router has enough slots to accommodate all desksets.

NOTES:

You can register only one AT&T TL7600 cordless headset to the MS2085 console or an MS2015 deskset. The system allows a maximum of one console and four desksets, or five desksets to have cordless accessories. When the console or a deskset has cordless accessories, they are all part of the same extension, and only one extension device can be used at a time.

You must have modular telephone jacks and electrical outlet not controlled by wall switch near where you install the console.

The auto attendant function is available only on the MS2085 console. Every individual phone in your telephone system MUST be assigned a unique extension number

for the intercom feature to work. See Set extension number on page 24. You must have a router with DHCP enabled for your system. This console does not assign any

IP to the system deskset. This telephone system does not support other telephones connected to the same telephone

lines for use.

Install the console close to the telephone jacks, a router and a power outlet not controlled by a wall switch. The telephone can be placed on a flat surface or vertically mounted on the wall (pages 14-18). For optimum range and better reception, place the console in a central and open location.

If you subscribe to high-speed Internet service (DSL - digital subscriber line) through your telephone lines, you must install DSL filters between the telephone line cords and the telephone wall jacks (see page 9 or 10). The filter prevents noise and caller ID problems caused by DSL interference. Please contact your DSL service provider for more information about DSL filters.

Your product may be shipped with a protective sticker covering the console display - remove it before use.

For customer service or product information, visit our website at

www.telephones.att.com or call 1 (800) 222-3111. In Canada, dial 1 (866) 288-4268.

Avoid placing the console too close to:

Communication devices such as television sets, VCRs, or other cordless telephones.

Excessive heat sources. Noise sources such as a window with traffic outside, motors, microwave ovens,

refrigerators, or fluorescent lighting. Excessive dust sources such as a workshop or garage. Excessive moisture. Extremely low temperature. Mechanical vibration or shock such as on top of a washing machine or

work bench.

Set extension number

Each individual phone (console or deskset) in the telephone system MUST be assigned a unique extension number for the intercom feature to work. The assignment is done when the console is initially setup. If you have to set a new extension number to this console after initial setup, you are recommended to do so before registering any system desksets.

the previous menu. To exit without making changes, press CANCEL.

You have to release the old extension number from the console to make it available for other desksets. See Release extension number on page 25 for details.

NOTES:

If the extension number is already being used, the screen briefly displays Extension no. already in use.

If you want to assign an extension number that is already being used, see Release extension number on page 25 to replace the number.
