how does a modern telephone work

[vehelpfulguy]

You talk into one end and your voice comes out the other end.

I think your question is too broad.

Do you mean the telephone itself?, mobile phones or land line phones?, the telephone network?, telephone exchanges?, mobile phone masts?

It is a kinda broad question. Maybe this will help.

Much the same as an old one, but with updated mechanics & electronics. Can you be more specific?
