By Interphone I mean the door phone.

I think, "Interphone" is used in french
and in german it is called "Türsprechanlage".

But I like the idea of using the SIP Protocol, because I can redirect
the doorphone to any places of this planet.  Even if I am not at home,
I can see people ringing ar the door

-40°C is very rare but it has to survive.

Normal estonian winter temperatures are between -15°C and -25°C.
So, the doorphone/interphone should work in this range.
