You mean, like, radio and automobile and antibiotics and transistors? Which would come in somewhere near the top on the list of inventions that are any good and had a significant impact on progression toward our present way of life.
The Italian Innocenzo Manzetti built a working telephone 32 years before Belll patented his device, and Bell would have certainly known about it and how it worked.
It all really depends on who gets the patent for it. I don't know much about it, but Bell had to go through a legal battle against Elisha Gray for the telephone patent. Many people consider Gray to be the true inventor because he made his before Bell but just didn't act quick enough to get the patent, which Bell eventually won.
