DT handset features

How to access a range of features using the DT series handset.

Mute the ringer

To temporarily mute the ringer, press the RMUTE softkey. The RMUTE label will flash to indicate that the ringer is muted. Press RMUTE again to un-mute it.

Redial a number

To redial the previously-dialled number without re-entering it:

  • Lift the handset and press the left-hand side of the circular silver ring at the lower right of the phone.
  • Observe that the last number dialled is displayed on the LCD display.
  • Press the hash (#) key. The number will automatically be called.

Return a missed call

If an incoming call goes unanswered, the iCall softkey label will flash on your display.

  • Press the iCall softkey to display a list of calls, and use the up- and down-arrow softkeys to scroll through the list of calls. Unanswered incoming calls are indicated by two exclamation marks to the left of the calling number.
  • To return a missed internal call, lift the handset while the extension number is displayed.
  • To return a missed external call, you will need to prefix it with 9 before dialling the rest of the number. To achieve this, press the rightmost softkey (labelled with three right-pointing chevrons: >>>), then the Prfx softkey. Press 9, then the OK softkey, and then lift the handset.

Three-way conversation

You can establish a three way conversation with two internal extensions and one external number.

  • Ask the connected party (internal or external) to hold.
  • Press the Transfer key.
  • Dial the destination number (external or internal).
  • When the call is answered, press the CONF softkey. This will establish the three-way conversation.

Please note that a multi-way conference with more than one external party is not possible using this mechanism. Such conference calls can be facilitated through the University switchboard - please contact Telephone Operations in advance to arrange this.

Call back to a busy extension

If you call another University extension and hear the engaged signal, you can establish a “call back”, so that you are automatically called when the extension becomes free.

  • When you hear the busy signal, press the CB (callback) softkey.
  • Replace the handset.
  • When the busy extension becomes idle, your phone will ring. Lift the handset and wait for the called extension to answer.

Divert incoming calls

You can arrange for incoming calls to your extension to be automatically diverted (or “forwarded”) to another extension. You can forward calls that are not answered, calls where your extension is busy, or all incoming calls.

To set call forwarding

  • Lift the handset.
  • Press the FDA (forward all) softkey, or use the rightmost >>> softkey so you can press the FDN (forward on no answer) or FDB (forward on busy) softkeys.
  • Dial the extension number you wish to forward to. If you are wishing to divert to an external line or to a mobile, the number will need to be prefixed with a 9. If you are forwarding to voicemail, the number is 517000.
  • The display will show FORWARD SET.
  • Replace the handset.

To verify call forwarding

  • Lift the handset.
  • FDA, FDN or FDB will flash if forwarding has been set. Note that you need to use the rightmost >>> softkey to display the FDN and FDB softkeys.
  • Replace the handset.

To cancel call forwarding

  • Lift the handset.
  • Press the flashing FDA, FDN or FDB softkey.
  • The display will show FORWARD CANCEL.
  • Replace the handset.

Using the phonebook

The phone has a built-in phonebook. This is associated with the extension number rather than the phone itself - thus if your extension is permanently moved to a new physical DT series phone, your phone book will be available on the new phone.

To save a number in the phonebook

  • Access the phone book –by pressing either the right-hand side of the silver wheel (with the book icon beside it) or the Pbook softkey.
  • Note that the Cnl (cancel) softkey will take you up a level in the menus – repeatedly pressing Cnl will return you to the start.
  • Press the Local softkey.
  • Press the Add softkey.
  • Enter the name using the keypad. You can use the leftmost softkey (labelled ->) to move to the next character position. To switch between upper and lower case letters, press the right arrow (>>>) softkey and use the left-middle softkey to select –Eu-s (lower case) or –EU-l (upper case).
  • Press the OK softkey.
  • Enter the number using the keypad (with initial 9 if the number is external).
  • Press the OK softkey.

To call a number in the phonebook

  • Access the phone book –by pressing either the right-hand side of the silver wheel (with the book icon beside it) or the Pbook softkey.
  • Press the Local softkey.
  • Press the Srch softkey.
  • Enter the first few characters of a name using the keypad.
  • If more than one name matches, scroll through the matches with the UP or DOWN softkey.
  • Lift the handset to call the number corresponding to the name being displayed.

Note that there is a "local" and a "system" phonebook. The "local" one is associated with your own extension, while the "system" one is currently not in use.

Programmable keys

Your handset has six programmable keys (12 or 24 on the larger models) located below the softkeys. These can be used as speed dial keys, and/or as part of a hunt or pickup group, or to support an executive/secretary relationship. To have these keys programmed to your requirements, please contact Telephone Operations.
