The device has touch function keys which you can program to suit your needs. Each function key has a multi-colour display that indicates its status, based on its assignment.
The number of programmable function keys on the device can be extended by adding up to three COMfortel D-XT20 or D-XT20i key extension modules (not included in the scope of delivery). Modules are attached to the right-hand side of the phone.
Note: If you connect more than one key extension module, use a COMfortel D-XT-PS power supply unit (not in the scope of delivery).
The programmable function keys on the key extension module can each be defined three times (on three levels).
Note: New parameters have been defined for some function keys (e.g. Speed dial) from firmware version 1.10. If functionality is restricted following an update to a higher firmware version, it might be sensible to delete the particular key and then configure it again.
LED signalling
Each LED indicates the status depending on the key definition.
*: The function key or the described behaviour of the LED is only visible if the function key has been provisioned by a PBX or activated by manufacturer templates.
**: The function key or the described behaviour of the LED is only visible if the function key was added by importing the corresponding template.

Process for assigning function keys using the phone
Setting up a new function key on the telephone:
•Add entry to list
Assigning a function to a free position between 2 function keys on the telephone:
•Use the directional pad keys to navigate to the relevant position.
•Insert
The new key is inserted above the selected key.
The numbering of subsequent keys is adjusted.
Setting up a new function key on the COMfortel D-XT20/-XT20i key extension module:
•Press a key that is not assigned (keys that have a function assigned to them shine yellow).
Note: If a key to which a function has not been assigned is pressed for a longer time (long press), the menu for configuring the selected key opens automatically.
•If necessary, change between key levels by pressing the control rocker.
Process for assigning function keys using the Web Interface
1.Select a button to which a function has not already been assigned.
2.Change to the right level, if required (Level 1– 3 tab, only extension module).
3.Select the function that is to be assigned to the key.
4.Set other necessary parameters, if necessary.
5.Save your settings.
The assigned key label is displayed on the display.
The key can be used with the function that has been assigned to it.
Extending the range of functionality using provisioning
You can use the templates in a provisioning file to extend the range of functions on the phone. These additional functions can be assigned to function keys.
•Suitable template < > phone assignment on the PBX
During the next provisioning process, the configurations in the template file are loaded into the phone. The additional PBX functions are in the Choose a function (phone) or Function menu (web interface) and can be assigned to the function keys.
Configured speed dial number can have a picture assigned to it
You can assign a picture, e.g. of the contact person involved, to a configured speed dial number, making it easier to assign a subscriber number to a contact.
Requirement for configuration:
•The URL of the external server on which the picture is stored
