VOIP (Voice over Internat Protocal)

Telephony is the field of technology involving the development, application, and deployment of telecommunication services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone.

VoIP, often known as IP telephony, is a technique and collection of technologies for delivering voice conversations and multimedia sessions over IP networks, including the Internet. The provision of communications services (voice, fax, SMS, and voice-messaging) through the Internet as opposed to the public switched telephone network (PSTN), generally known as regular telephone service, is explicitly referred to as Internet telephony, broadband telephony, and broadband phone service.
