When did they make the first Telephone?
Alexander Graham Bell is credited with the invention of the first practical "electrical

By 1878, Bell had set up the first telephone exchange in New Haven, Connecticut.
By 1884, long distance connections were made between Boston, Massachusetts and
New York City.

The Silver Dart is on permanent display at the Alexander Graham Bell Museum in Baddeck…
