The dial plate telephone "FeTAp 611-2" (Fernsprechtischapparat) in screaming orange was distributed by the German Bundespost from 1972 on. It uses a real bell for ringing and of course it can only do pulse dialing. This was recorded with a single Røde NT5 microphone via a Behringer DDX3216 digital console into Ardour. Not edited.
Edit Feb 2020: I changed the license to CC0 since I myself use CC0 material from Freesound these days a lot.
