One of the foremost tools of business is the telephone that helps not just the customer to connect to the company personnel but also vice versa.
The telephone as an instrument of communication was first invented by Alexander Graham Bell who became the sole inventor of the device when he got it patented in the year 1870, ahead of another, Elisha Gray who was also onto the invention of a similar device at the very same period of time.
The first telephone call ever was made by the inventor himself, from New York to Chicago in the year 1892. And since then, the telephone has changed not just shapes and sizes but use as well, as the rest as they say, is history.
