Installing phone intercom in my flat

[Wellredd219]

Hello I'm new here I'm currently trying to install a phone intercom into my flat but I have no idea of where the wires go.

Below is a picture of the phone system I bought which is a 887U ELVOX. Thanks in advance for the assistance.

I assume there is a front door unit which serves all the flats and you are replacing the handset in your flat.

If that is the case then you need to speak to the people who installed / maintained the system as only they will know which wire does which function.
