The 8410D is a ten-button telephone with speakerphone and alphanumeric display.

Call Appearance &
Feature Buttons

There are ten programmable extension (call) appearance and feature buttons in the center of the telephone. These buttons vary in how they are programmed depending upon the function of the person using the telephone. The features described below can also be accessed by using feature codes indicated in [brackets].

The dark purple italicized headers below indicate features that can be programmed by the ITS Communications & Computing Services Department.

Extension (Call) Appearances

These buttons are marked with the extension numbers (the last five digits of the telephone number) that are programmed onto the buttons. Principals typically have three appearances of their extension. Persons covering main department numbers and other people's phones may have appearances of their own extension, appearances of the department number, and cover lines for answering calls for other people.

Call Pickup

Allows you to answer calls placed to other extensions in your group or department without having those extensions on your phone.

To use:

  • Lift handset or activate the speaker, then press the Call Pickup button [or dial #4].

Send Calls

When activated, all your calls go directly to your next point of coverage—either voice mail or a cover person. A single ring is heard when the feature is activated.

To activate:

  • Press the Send Calls button. (Green light will go on.) [Or lift handset and dial *3.]

To deactivate:

  • Press the Send Calls button. (Green light will go out.) [Or lift handset and dial #3.]

Last Number Redial

Redials the last telephone number you dialed.

To use:

  • Lift handset [or press Speaker].
  • Press the Last Number Dialed button [or dial *1].

Call Coverage

Calls to a person's extension can be programmed to progress to voice mail or to another phone or phones and then to voice mail. The norm is three rings before the call progresses. Two to six rings are possible. Please see the help page for instructions on how to place an order for (or change) this feature.

Cover Line

Used on the phones of those people who cover for the calls of others. This is a call appearance of an extension to which coverage calls (see above) will ring. Note: A cover line cannot be dialed directly. Calls reach the cover line either through call coverage or when someone has pressed the zero option in voice mail (opting to speak with someone).

Call Forwarding

Allows you to have your calls ring at another NYU extension instead of your own.

To activate:

  • Lift handset or activate Speaker, dial *2.
  • Enter the NYU extension to which you wish to forward your calls. (You will hear a three beep confirmation tone.)

To deactivate:

  • Lift handset or activate Speaker. Press the call appearance button of the forwarded line. Dial #2. (You will hear a three beep confirmation tone.)

Transfer to Voice Mail

If you have answered a call for a coworker through call pickup or call coverage, you can transfer the caller to the coworker's voice mail without calling the coworker's number.

To use:

  • Press Transfer.
  • Dial *4.
  • When voice mail greeting begins, press Transfer.

Fixed Feature Buttons

These are the nine buttons on the lower left of the phone. They are described below.


Use the Volume toggle button to raise and lower the ring volume, the loudness of the speakerphone, or the loudness of the volume heard through your handset.

  • Press the left side of the Volume button to lower the volume, and the right side to raise it.

Shift or Ring

[Some 8410Ds do not have a Shift button.] The Shift button is used to reset the Speaker and the Ring Pattern (see Speaker and Selecting a Ring Pattern). The Ring button is used to select the ring pattern.


To send a call to another NYU extension:

  • Press Transfer. (This places the caller on hold.)
  • Dial the extension to which the call is to be transferred. (When the party answers, announce the call.)
  • Press Transfer again and hang up. (If the party does not wish to accept the call, press the call appearance button where the green light is flashing.)

Conference-Six Party

The conference feature allows you to connect up to six parties, including yourself.

To initiate a conference call:

  • Get first party on the line.
  • Press Conf button. (First party is on hold).
  • Dial the number of the new party, wait for an answer and announce the conference.
  • Press Conf button again. All parties are connected.
  • Repeat previous three steps for each additional conference connection.

To conference a caller you have on hold with a party you are speaking with on another call appearance:

  • Press Conf again. All parties are connected.


Use in conjunction with the speaker.

  • Press Mute again to resume talking to party. (Red light goes out.)

To use:

  • Press Drop.

Resetting the Speaker

To adjust the Speaker to the surrounding room acoustics:

  • If your phone does not have Shift button: If the light next to the Speaker button is flashing, simply press the Speaker button.


Used to place a call on hold.

To answer a new call while active on a call:

  • Press Hold. (Initial call is on hold; green lamp will flash.)
  • Press the call appearance button of the incoming call.

Selecting a Ring Pattern

There are eight different ring patterns. A particular ring pattern can help you distinguish your phone's ring from others around you. The ring pattern can be set by using the Shift or the Ring button; your telephone will have one or the other.

To use:

If your phone has a Shift button:

  • Press Shift.
