Door signal while handsets are busy

What happens if a button of the Gigaset HC450 is pressed during a telephone call?

You are in a telephone conversation with an internal or external participant, and a button of the Gigaset HC450 will be pressed.

 

In this case the Gigaset HC450 behaviours as same as another call of an internal or external participant comes in.

A short knock signal appears once in the handset which is in use if more than one handset is registered to the base station, and the Gigaset HC450 calls all registered handsets (default setting in the HC450), all these handsets would ring, while the one in use would announce the knock signal.

Additional to the acoustic signal each called handset displays the call visually like an internal call. The name of the Intercom will be displayed.
