"Bell didn't really invent the telephone:

lacked key features we associate with the phone

-a ringer (invented two years after Bell's patent)

-a dial (invented by Edison)

Bell invented the Intercom

-Edison probably did more to turn it into a telephone than anyone, We even adopt his greeting (Hello) in preferences to Bell's (Ahoy)

But Bell invented something far more important

-Microphones and Speakers"

Users created the telephone:

By demanding ways to call multiple endpoints

By requiring easier to use summons signals

By creating new ways to use the telephone

By adopting means of behavior"

How does an audio door intercom powered by solar operate?

It operates exactly the same way as any other intercom. The only difference is how it gets its power. As an example, the intercom at the following site can run on battery power, AC power, or it has a solar power option. Whatever intercom you use, you'll have to consider that an intercom near a doorway may be shielded from the sun so the solar panel will likely have to have a long cord on it. You may be able to find some sort of solar panel you can use to convert any battery-powered intercom to solar. Just look for one that has the right voltage and current output to match the intercom.
