VoIP or Voice Over Internet Protocol is a modern substitute for traditional phone lines that make communication efficient using the Internet. The main motive behind the invention of VoIP technology is to lower domestic and international telephone charges. 

There are two types of VoIP systems: fixed and non-fixed VoIP. One of the common traits of both technologies is that they allow users to make calls from any part of the globe at a cheaper rate.

In this article, I’ll dig deep into fixed and non-fixed VoIP systems. So, without any further ado, let’s get started.

What is a Fixed VoIP Phone Number?

A fixed VoIP phone number is linked or attached to a physical address. In other words, it is an internet-based phone line connected to an actual address and an account owner

The phone number will be linked to that specific address even if you switch to another VoIP provider. Since fixed VoIP numbers are tied to a specific location, businesses carry a professional aura among the clients.

Most importantly, due to their physical presence, they aren’t seen as spammy compared to the non-fixed VoIP numbers.

What is a Non-Fixed VoIP Phone Number?

A non-fixed VoIP phone number, also referred to as a virtual phone number, is not linked to a specific address, just like a fixed VoIP phone number. It is dedicated to a person or a device. 

It lets you make calls anytime, in any part of the world, via the Internet. The primary benefit of the non-fixed VoIP phone number is that such phone numbers can be handy for making and receiving calls from anywhere. 

Businesses that don’t have physical locations love this flexibility and consider this a better option than having a fixed VoIP phone number.

Shaping up your business starts with the right phone system. Voice over Internet Protocol (VoIP) provides exactly that. The only question that arises is which one to go for, either fixed or non-fixed VoIP.
