As businesses increasingly adopt internet-based solutions, the VoIP phone has emerged as a vital tool for enhancing communication efficiency. Unlike traditional landline phones, VoIP phones use internet protocols to transmit voice data, allowing for greater flexibility, lower costs, and a rich suite of features.
This guide covers everything you need to know about VoIP phones, including how they work, the types available, benefits for businesses, and key features to look for.
What is a VoIP Phone?
A VoIP phone (Voice over Internet Protocol phone) is a device that makes and receives calls over the internet instead of through conventional telephone lines. It can be a physical desk phone with IP capabilities or a software-based phone (softphone) installed on a computer or smartphone.
VoIP phones are a core component of modern business phone systems, especially those using hosted PBX or cloud communication platforms.
How Does a VoIP Phone Work?
VoIP phones convert your voice into digital signals that are transmitted via your internet connection. These signals are sent to the recipient, decoded back into audio, and heard on the other end.
VoIP phones connect to your network through:
- Ethernet cables (wired IP phones)
- Wi-Fi (wireless IP phones)
- Mobile data or apps (softphones)
They communicate with VoIP servers or cloud PBX systems to manage call routing, voicemail, caller ID, and other features.

Ideal for office desks, they often include features such as HD audio, call transfer buttons, and support for multiple lines. They’re best suited for staff with a fixed workstation and regular call activity.
2. Wireless VoIP Phones
Wireless VoIP phones operate over Wi-Fi, giving users the flexibility to move around while staying connected. These are perfect for open offices, warehouses, or retail environments where mobility is essential. They often come with features like roaming support and extended battery life.
3. Softphones
Softphones are software applications that turn your computer, tablet, or smartphone into a VoIP-enabled phone. They’re cost-effective and highly portable, making them ideal for remote workers and hybrid teams. Most softphones support video calls, screen sharing, and integration with business tools.
4. Video VoIP Phones
These advanced phones include built-in cameras and screens for video conferencing. Ideal for executive offices or meeting rooms, they support face-to-face collaboration without needing a separate video setup. Many models support high-definition video, touchscreen controls, and integration with conferencing platforms. Equipped with cameras and screens for video conferencing in addition to voice calls.
