Voice over Internet Protocol (VoIP)
What is Voice over Internet Protocol (VoIP)?
Voice over Internet Protocol (VoIP) is a technology that allows voice communications and multimedia sessions to be transmitted over the Internet, rather than relying on traditional circuit-switched telephone lines of the Public Switched Telephone Network (PSTN). Instead of using dedicated copper wires to carry voice signals, VoIP converts voice into digital data packets that travel across IP networks, just like emails or web traffic. This approach not only reduces costs compared to conventional phone systems but also enables advanced features such as video calls, voicemail-to-email, call forwarding, and integration with other digital applications.
What Is the Difference Between VoIP and Landline Phones?
The main difference between VoIP and landline phones lies in how they transmit voice calls. Landline phones rely on the Public Switched Telephone Network (PSTN), which uses physical copper wires to carry analog signals. This infrastructure has been in place for decades and is renowned for its reliability; however, it can be costly to maintain and is limited in features.
VoIP phones, on the other hand, use the Internet to send and receive calls by converting voice into digital packets that travel across IP networks. This makes VoIP more flexible, cost-effective, and feature-rich compared to traditional landlines. Businesses and individuals benefit from options such as video conferencing, call forwarding, voicemail-to-email, and integration with mobile and desktop applications. These are capabilities not typically available with standard landline services.
In short, landlines are tied to physical infrastructure and limited functionality, while VoIP leverages modern Internet technology to provide scalable, affordable, and versatile communication.

- Cost savings: Lower calling rates, especially for long-distance and international calls, compared to traditional landlines.
- Scalability: Easily add or remove users without requiring new physical phone lines.
- Mobility: Make and receive calls from virtually anywhere with an Internet connection using smartphones, tablets, or computers.
- Voicemail-to-Email: Receive voicemail messages directly in your email inbox for easier access and management.
- Call forwarding and routing: Redirect calls to different devices or team members to ensure important calls are never missed.
- Video conferencing: Host face-to-face meetings online with built-in video and screen-sharing capabilities.

- Advanced call management: Features such as call recording, auto-attendant, and interactive voice response (IVR) enable professional call handling.
With these features, VoIP empowers businesses and individuals with flexibility, efficiency, and functionality that traditional landlines simply can’t match.
How To Switch to VoIP
VoIP’s list of advanced features can make the process of migrating to VoIP sound intimidating. The good news is that providers should help you with this part. Broadly there are two main steps.
Start by choosing a reliable VoIP provider. You need two resources:
- A quick guide on how to pick the right provider
- VoIP provider checklist
Purchase or port numbers with your VoIP service. Now that you’ve chosen your provider, you set up your VoIP either by purchasing new numbers or porting existing numbers. Ideally, you will be able to use your provider’s dashboards to configure features, i.e. SMS or caller ID. Be sure that your new VoIP service can offer a streamlined provisioning service so you can configure these numbers quickly, especially for larger teams.
VoIP (Voice over Internet Protocol) works by converting your voice into digital signals, sending them over the internet, and then converting them back into sound on the receiving end. Instead of relying on traditional telephone lines, VoIP uses your internet connection (Wi-Fi, broadband, or mobile data). This allows calls to be made from computers, smartphones, VoIP phones, or even traditional phones with an adapter.
VoIP is often more cost-effective, especially for long-distance or international calls. It also offers greater flexibility since you can make and receive calls from anywhere with an internet connection. Beyond that, VoIP systems typically come with advanced features like video conferencing, voicemail-to-email, and call forwarding, making them a powerful alternative to basic landline phone systems.
Examples of everyday apps and platforms using VoIP include Skype, Zoom, WhatsApp, Google Voice, Microsoft Teams, and FaceTime Audio. On the business side, services like RingCentral, Vonage, and Nextiva are widely used, while consumer-focused options such as Ooma and MagicJack also run on VoIP technology.
