The term VoIP stands for Voice over Internet Protocol. This is a technology that supports the real-time transfer of voice information digitally over the Internet. VoIP allows users to bypass the public switched telephone network (PSTN) for cost savings. They can make telephone calls over their computer networks. VoIP systems convert analog voice signals into data packets. After businesses and residences choose VoIP service providers, they can make calls using audio systems. They can also use traditional telephones which have been connected to a computer network through a VoIP adapter. Professional IP telephone systems and voice communication accessories should have interoperability with a service provider’s VoIP infrastructure.
VoIP Equipment and Devices
ATA is the acronym for an analog telephone adapter. It serves as an interface between the PSTN telephone system and a digital phone line. This type of adapter is a common piece of VoIP equipment which is required when a regular telephone will be connected to a network. No adapter will be needed when PC-to-PC VoIP is used. Adapters that connect telephones to LANs may be referred to as gateways. These VoIP devices communicate with the VoIP server without software telephone programs and are often utilized by commercial enterprises.
IP Telephony Transmits Voice Data
Telephony is the science of telephone service. IP Telephony describes the hardware and software which allows users to make phone calls with the Internet as their medium for transmission. With IP telephony service, voice data is transmitted in packets using Internet Protocol. In comparison, PSTN uses circuit-switched networks.
