VoIPs meaning in technical terms

Voice over Internet Protocol is a group of software and hardware that allows people to use the internet as the transmission channel for telephone calls. The main difference between VoIP and traditional phones is that VoIP sends voice data in packets using IP instead of traditional circuit transmissions of the Public Switched Telephone Network PSTN. Also VoIP phone systems do not use phone lines in the traditional sense of the term.

For VoIP implementations, you need to have a computer, VoIP software, and an internet connection. You also need either an analog telephone adapter, a microphone or Voice over IP VoIP telephone. Others need VoIP phones, which are like regular telephone handsets, but generally, connect to your computer via USB. Analog telephone adapters enable you to use regular phones with your computer. IP phones are another alternative that connect directly to the router or wireless broadband through ethernet or wirelessly. In this feature, you are going to learn about what VoIP phone is and other related questions that you may have.

VoIP is also known as IP telephony, digital phone, or internet telephony.

What is a VoIP phone system and how does it work?

How internet telephony works?

VoIP is often known as IP telephony since it uses internet protocols to make possible enabled voice communications. The internet protocols are the fundamentals of IP networking, which supports private, corporate, cable, and even wireless networks. VoIP technologies enable unified communications by uniting an organization’s many locations, including mobile workers into one converged communications network and offers an unparalleled range of telephony support services and features.

Before digital networking came into the picture, everyone had to use POT. POTS runs over PSTN. The POTS telephone systems use the tried and true approach of telephone service referred to as circuit-switched. For clients, the costs associated with the regulated circuit switching PSTN remain much higher than they require to be. Clients and businesses that depend on the POTS way of telephony indicate to the bottom line. The cool part is that Voice over IP is an alternative that can significantly decrease or remove POTS-associated costs. VoIP also improves productivity, leaving a bigger budget for other things in the office than paying telephone bills.

IP telephony operates by taking traditional voice signals and changing them to digitized voice (a kind that can be transferred efficiently over a local area network) (LAN). Therefore, the center of IP telephony is the same as traditional data networking with computers. IP-enabled phones manage the voice data conversation well; however, do not be mistaken. Adopting VoIP does not mean everyone has to use IP-enabled phones.

The best Voice over IP service providers implement IP telephony in a manner that protects your investment in existing telephone equipment, even though you have an analog telephone station.
