What does telephony mean?
Telephony is the technology and practice of transmitting speech or other information through telephone networks. Its meaning includes both the systems that make telephone communication possible and the broader field of research and development concerned with those systems. In modern usage, telephony often appears in technical expressions such as mobile telephony, fixed-line telephony, and telephony services, while telephone is more likely to refer to an individual device or call. Historically, telephony transformed communication by allowing voices to travel over long distances, first through wired networks and later through wireless and digital technologies. The word is especially useful when discussing telecommunications, network infrastructure, business connectivity, and the social effects of rapid communication. Although it can occasionally be used in more general senses, its standard modern use is technical and typically refers to voice communication rather than every form of electronic messaging.
