You can use the phone to make internal (on the PBX) and external calls.

During a call, you see information about the call and your call partner on the screen, as well as general time information (date and time).

The selected numbers and characters are displayed in the screen for some seconds and you can hear the associated sound.

A call that has been taken on a different internal phone can be picked up, provided that call pick-up has been permitted on the PBX for the subscriber that is being called.

This function is useful, for example, in the case of answering machines.

When your call partner ends the call, your phone goes into its idle state. If you hang up the receiver, you will hear the busy signal through the base unit loudspeaker if the receiver has been hung up incorrectly.
