The telephone was always thought of as a one person device. The patented magnetic recorder was, believe it or not, an answering machine. The necessity for a group of people to listen to the same thing at the same time came about with the marketing of the radio in the 1920s. The first loud speakers were phonograph horns attached to a larger than usual telephone receiver. You had it right but it took a while.
