In fact, this was the first phone . However, discoverer of the phone got amerikanskomuTelefon inventor Alexander Graham Bell Bell patented his telephone February 14, 1876 . Simultaneously with an application for a similar device , another American inventor filed Elish Gray. But since it was filed on 2 hours later , a patent was issued Graham Bell . Later, Gray filed a case against the opponent , but lost it. But despite the inconsistency of this discovery , it marked the beginning of a new era in the field of communications - telephony era . In 1878, Thomas Edison perfected the telephone by entering the circuit induction coil and the carbon microphone . This has greatly increased the distance between subscribers . In the same year, was commissioned first telephone exchange in a small American city of New Cheyven . In 1887, Russian inventor K.A.Mostsitsky created automatic switch, which foreshadowed the creation of automatic telephone exchanges . By the way the first audio message transmitted by telephone Bell was: "Mr. Watson, come here , I need you . " In Russia, the first telephone conversation took place in 1879
