Interphone with SIP-Protocol

["Michelle Konzack" <linux4michelle@tamay-dogan.net>]

Hello Guys,

OK, I live now since last year permanently in Estonia and have now a 4ha
(13ha max) Organic Farm with 5,6ha forest.  Because I live in a loghouse
I have build a fire and storm proof "Serverbunker" where my Intranet
Server with its own power supply reside (the Mainpower supply will be
cut at stomy weather).

>From theis Serverbunker I go (Lighting protection) with Multimode Fiber
Cabesl (100Base-FX) to the House, Powerstation, Greenhouse, Earth-
storrage and of course to the Portal.

Because my Portal is in a distance of 60m from the Serverbunker and I do
not like to install a seperated earth cable, I am now searching for an
IP/SIP based Interphone.  Best would be with Video.

Has someone experience with it and can suggest me a product?

Note 1: We have currently -10°C on the Farm and it can go down
        until -30°C (some years ago it was for one day -39°C),
        which increase the requirements on the Interphone.

Note 2: In 2017/2018 i used a Banana PI at a Sidele Interphone,
        but the BPI gaved up at -5°C and the Siedele at -20°C.

Thanks in advance
