Voice over Internet Protocol, also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol networks, such as the Internet.
With the rise of broadband, VoIP has become the definitive choice for phone service for consumers and businesses.
People enjoy using VoIP phone service over traditional phone lines. Why? It offers many more capabilities than analog phones. And it can do it all for less than half the cost.
Cloud phone service providers include powerful features not found with standard phone service. Auto attendants, call recording, custom caller ID, voicemail to email, and so much more. Plus, you can take calls and work from anywhere.
How does VoIP Work?
Voice over IP uses Internet Protocol, an essential building block of the internet. IP telephony is a massive innovation from the century-old telecommunications system.
For phone calls, the conversation is exchanged using small data packets. The internet can send these data packets around the world in less than a second. For internet telephony, these packets travel between your phone and a VoIP provider.
A VoIP phone system facilitates calls between other phones or over to another telephone company. It also provides other useful functions like voicemail, call forwarding, call recording, and more.
In four steps, here’s how VoIP works.
- Your phone connects to your switch or router in your Local Area Network (LAN).
- When you dial a telephone number, your IP phone tells your VoIP service provider to call the other party.
- Your VoIP service establishes the call and exchanges data packets from your IP phone.
- Your VoIP phone converts these digital signals back into the sound you can hear.
Voice over Internet Protocol bypasses the telephone company entirely. Wherever you have a broadband internet connection, you can use VoIP. It’s a significant upgrade from an analog phone system.
You used to need expensive, proprietary equipment to use VoIP — but that was over 20 years ago! Today, VoIP is built upon open standards such as Session Initiation Protocol (SIP). SIP provides complete interoperability between different desk phones, conference phones, and VoIP apps.
Cloud-based PBXs are responsible for features like voicemail, conferencing, and call routing. When you think about it, they act as their own full-service phone companies that you control.
All you need is a broadband internet connection (cable, DSL, or fiber) and you can reap all the benefits of VoIP.
