In reality, it was the German "Philipp Reis" who invented it. In Friedrichsdorf he made the first prototype and also invented the special (coal based) contact microphone used in phones ~ 1990. He demoed the prototype in 1861 before the physical society in Frankfurt/Main.
Later on he sold phones in quite low quantity, usually to experimenters. Examples of the phones made it as far as to Russia or Scotland. Bell, who was too from Scotland, learned about Reis' telephone in Edinburgh in 1862.
Bell reverse-engineered it, improved it, and created a successful business around it. And that's not something shabby...
... but he definitely didn't invent it. Not even the name. "Telephon" was the name that Philipp Reis already used.
Philipp Reis was the phone inventor. See my other post below for some details.
The article mentions something I forgot though. Sometimes the weather is shit!
A few years later I read an article about some laser based relay on Hackaday, and it blew my mind. My school had fiber internet and I fantasized about setting up a relay of lasers so I could have super fast internet at my house.
Of course the shit weather thing affects lasers too (fog, rain, etc.), but you'd get a little more uptime :)
