To ensure you harvest every benefit of this growing technology, we have created a complete guide, breaking down everything you need to know about VoIP phone service.
What is VoIP Phone Service, and How Does It Work?
At its core, VoIP stands for Voice over Internet Protocol. This technology allows you to make and receive calls over the internet instead of traditional phone lines. It converts voice into digital packets which are then transmitted over the network all the way to the receivers’ end.
How Does VoIP Work?
Let’s dive a little deeper into how this technology works. VoIP utilizes packet-switched protocols to transmit voice data. Here’s a simplified breakdown:
- Voice Capture: When you speak into a VoIP device, your voice is captured as analog signals.
- Digital Conversion: These signals are converted into data packets.
- Data Transmission: The packets travel over the internet to the recipient.
- Reassembly and Playback: The data is reassembled and converted back to audio on the recipient’s device.
In a nutshell: VoIP converts your voice into digital signals, transmits them over the internet, and then reconverts them into audio for the recipient. This seamless process eliminates the need for conventional copper wires, making communication faster and more cost-effective.
This process ensures clear and uninterrupted communication, provided you have a stable internet connection.
What is the Difference Between VoIP Phones and Landlines?
While both systems facilitate voice communication, the differences between VoIP phones and landlines are significant:

With VoIP, businesses gain access to modern features and greater flexibility at a fraction of the cost of landlines.
Types of VoIP
There are two different types of VoIP services – Hosted PBX and On-Site PBX services. Hosted VoIP services are those wherein the phone connects through the internet connection to a VoIP provider who maintains the hardware and equipment at an off-site location.
On the other hand, On-Site VoIP services are those where the hardware and the equipment required for VoIP services are maintained on-site inside the business server room.
With Hosted VoIP services, the business places the majority of the IT responsibilities with the service provider, meaning the burden related to maintaining and monitoring the VoIP system lies with said provider. There is no need for the business to have additional IT staff and training to operate VoIP services. However, businesses still have to configure the devices’ connection to the PBX server, firewall settings, etc.
With On-Site VoIP services – all the hardware is kept within the business, thus providing better opportunities for customization. Businesses get the freedom to customize various features, including call routing and scalability. But, when the majority of the hardware is kept on-site, businesses are recommended to have trained IT staff to better manage the operations—and this can increase the final cost.
