This was a real phone that you could buy from (I believe) the national carrier in the late 80s / early 90s.
I didn't know anyone with one myself but I do recall seeing them for sale and I'm pretty sure it was in the telephone book that I saw it (that was how you chose your phone in those days for most people).
We just had a shite beige one with the same receiver and buttons but it did do the beep boop instead of the tok tok tok which was great. Old people will understand.
