Please refer to the administration portal manual for detailed information.

Program field keys freely programmable as function keys

As you can see on the telephone (KX-UT133 and KX-UT136) the function keys start at 1 (1 to 24).To configure the telephone’s function key 1 via the service site, please select number “0”. For function key 2, please select number “1”, etc.

  • You can use only 23 of the 24 function keys on the telephone models KX-UT133 and KX-UT136.

  • The last fuction key is configured as a line key.

  • In case you decide to use all of the 23 function keys, you will be able to do a blind transfer only.

Telephone number

You can program any telephone number to one of your function keys. Pressing the programmed function key then starts a telephone call.

Busy Field Light (BFL)

You can program any extension to one of your function keys. Pressing the programmed function key starts a telephone call.

A flashing LED for the respective function key indicates an incoming call to the extension. To pick up the call, simply press the flashing function key. In order to pick up calls, all parties must be members of a pick-up group. You have now picked up the call.

If the monitored extension (Busy Field Light (BFL)) is busy, the LED for the respective function key remains lit.

Intercom

Program any extension to one of your function keys, to then be able to communicate with this extension directly via the intercom by pressing this function key. However, the other party must also have the intercom activated on their telephone. Intercom refers to a conventional intercom system (similar to walkie-talkies), directly connecting you to the other party’s speaker by pressing the assigned function key.

Function code

You can also program functions such as call forwarding to function keys by entering various codes (see “Functions via control codes (* codes)” leaflet). Pressing the programmed function key then activates or deactivates this function.

Services

Program any telephone system feature (queue, caller group, virtual conference room, etc.) to one of your function keys. This requires the service being assigned to an extension. Pressing the programmed function key then initiates a call to the service.
