What is VoIP?

VoIP is the acronym for Voice over Internet Protocol, which allows anyone to make calls via an Internet connection. It is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular telephone line. With the rise of broadband, VoIP has become the ultimate choice for telephone services such as consumers and businesses.

How does VoIP work?

VoIP service converts your voice into a digital signal transmitted over the Internet. Today, there are three different types of VoIP services:

ATA: This is the simplest and most common form of VoIP call. By using ATA (Analog Phone Adapter), you can connect a standard phone to a computer or Internet connection for VoIP. ATA is an analog to digital converter that takes analog signals from your mobile phone and converts them into digital data for transmission over the Internet. It is very simple to use, so it has been widely adopted worldwide.

IP phone: IP phone is a kind of special phone, it looks like an ordinary phone, with the common handset, base and buttons you want to see, but the IP phone does not have a standard RJ11 phone connector, but has RJ45 Ethernet connector. IP phone connects directly to your router and has all the on-board hardware and software needed to handle IP calls.

Computer to computer: In all three major systems, this will be the easiest way to use VoIP. Computer to computer VoIP calls use software loaded on your PC or device, microphone and speakers, and your Internet connection so that you can make calls between computers. Popular services such as Skype use this VoIP platform to provide services.
