1st transcontinental telephone call


Description

A telephone call, which for marketing purposes is claimed to be the first transcontinental telephone call, occurred on January 25, 1915, a day timed to coincide with the Panama–Pacific International Exposition celebrations. However, the transcontinental telephone line was first completed on June 17, 1914, and successfully first voice tested in July 1914. A 1998 U.S. postage stamp commemorates the completion of the line in 1914.
