Voice over Internet Protocol (VoIP) is a virtual communication technology enabling users to make real-time calls, texts, or connect via various channels irrespective of their geographical location or Internet-enabled device.

A VoIP number is associated with your business phone system, offering several distinct types to select from. This overview explains the fundamentals of VoIP phone numbers, including their operational mechanism, disparities from traditional analogue phones, diverse types available, advantages, and additional pertinent insights.

What Is A VoIP Number?

A VoIP number represents a genuine telephone number that utilizes the Internet to make and receive calls. Unlike traditional phone lines linked to the PSTN (Public Switched Telephone Network), VoIP numbers are not tethered to a single physical location, phone line, or device. Each VoIP number can be assigned to an individual user, an entire businessentity, or a specific department, offering unparalleled flexibility. Since VoIP phone service operates in the cloud, your entire business phone system remains accessible on any device with a broadband or wifi Internet connection. It means that incoming calls to your VoIP phone number can be answered seamlessly from a desktop computer, smartphone, VoIP-enabled landline, or tablet.

The softphone interface, which mirrors the appearance of a touch-tone keypad, serves as the central control hub for VoIP phones. Accessible via compatible mobile apps on desktop and mobile devices, the softphone application allows users to initiate and receive calls, configure call routing paths, participate in conference calls, adjust audio settings, transfer calls, and perform various other functions essential to efficient communication management.

How Does VoIP Phone Number Work?

A VoIP number operates by converting traditional analogue phone audio into small digital data packets that traverse the Internet to their intended destination, where they are reconstructed into clear voice audio.

Unlike analogue (rugged phone) voice calls, which use the PSTN circuit switching method and necessitate physical connection points, VoIP employs packet switching to transfer audio. This method doesn't rely on physical connections to transmit voice signals. Instead, packet switching breaks down voice data into smaller packets containing the caller's voice audio signals. These packets travel via broadband Internet to their destination and reassemble upon arrival at the recipient's end.
One distinguishing feature of VoIP technology is its ability to assess the most efficient path for these data packets to travel, thereby enhancing audio quality and optimizing bandwidth usage. Unlike the circuit-based PSTN, VoIP dynamically adjusts routing to ensure efficient transmission of voice data packets.
