The problem with a rotary phone collection is that they screw with DSL internet (and thus aren't as practical as keyboards). Put one of those on the line and every time it rings you'll lose your connection (assuming you have a respectable number of other phones on the same line...in my case, 4).
I'm no telecom geek but ringer equivalence numbers are not a myth, if you exceed a certain number your line won't work properly for anything (and another problem, 'line leak', is a common issue for old phones, good or otherwise - quoting multiple DSL service technicians who've had to inspect each of my phones for exactly that).
Interesting. I've got cable internet/phone service and 4 rotary phones connected and I don't have any problems. I expected many problems, but nothing so far.
I was very surprised to find that every single automated phone service I've tried - including telephone banking - works without problems. Of course, entering long account numbers takes longer to dial (especially if it has lots of damn "9"s and "0"s), but it works. I don't know what I'll do if it says, "Press # for more options"... but I haven't run into that yet.
I used to like unscrewing the earpiece and pocketing the microphone/speaker on those. Many lulz.

Check the dates on them. If you've got any from 1953, let me know. :eyebrows:
Mine is nothing special. Not very unusual or old. Inexpensive, plain and very very common, although the red or black ones are not as common as the white or grey. The grey phones have yellowed a bit by now.

Hey, that's not red - it's orange! I knew you Swedish people were crazy. What do you call "orange" - yellow?
(reminds me of the Simpsons quote, "No, your other left... Texas left - which is your down.")
