What Is a Non-Fixed VoIP?

Whenever we talk about remote working, cloud computing, and remote log-in to a business network, we are relying on the ability to access something without any form of geographical link. The development of cloud architecture makes this possible for businesses of all sizes, transferring data and information into a virtual space that can be accessed using the right credentials and the right device settings.

In the case of a non-fixed VoIP (Voice over Internet Protocol), the concept is much the same—eradicating the need for a physical location or connection, and instead enabling the user to communicate through their VoIP device from anywhere in the world.

How does non-fixed VoIP work?

Non-fixed VoIP numbers are also known as virtual phone numbers, because they don’t require a landline connection. Non-fixed VoIP works if you want to get access to a quick line to make personal calls or cheap international calls. Such numbers are assigned to users rather than locations, and are sometimes known as “virtual phone numbers.”

An example of a non-fixed VoIP in action is WhatsApp calling and Skype, both of which rely on an internet connection on both ends and can be linked to a mobile device for use on the go. These platforms help businesses connect with international partners and clients with a variety of call features, chat functions, and screen-sharing capabilities that support effective and efficient communications. None of this would be possible without a non-fixed VoIP.

Non-fixed vs. fixed VoIP

One of the main questions consumers have is, What’s the difference between fixed and non-fixed VoIP numbers? In short, fixed VoIP numbers are tied to an account holder’s physical address—a company’s geographical location or a home address. Non-fixed VoIP numbers are not tied to a physical location.

That leads us to the next question: If VoIP communication is controlled by the internet, do you ever really need a physical location in order to use your device?

In short, the answer is no—you don’t necessarily need a physical location, and this is where the non-fixed VoIP numbers come in. But that doesn’t mean fixed VoIP isn’t valuable. A fixed VoIP number is generally linked to a specific business location, using a local area code to give it a reputable local number. A fixed VoIP number also permits you to operate only over a secure network to ensure business confidence.

A non-fixed VoIP number, meanwhile, presents more freedom, lower costs, and a more reliable service—benefits we explore later in this piece.

Who uses non-fixed VoIP?

A non-fixed VoIP connection combines the value of the cloud with mobile devices. It presents businesses of all sizes the opportunity to communicate and operate remotely—factors that became especially prevalent during the 2020 pandemic when remote working became the norm for businesses around the world.

In terms of usability today, non-fixed VoIP numbers tend to be most popular with larger businesses that boast a global footprint and need to communicate with employees all over the world without incurring expensive international call fees. Non-fixed VoIP numbers are also popular with businesses needing to simply connect with employees working locally but away from a specific office location.

If this sounds like your business, a non-fixed VoIP might be right for you. But let’s talk about the benefits and challenges you should consider first.

The benefits (and challenges) of non-fixed VoIP

We’ve already hinted at a couple of the benefits of using a non-fixed VoIP, particularly in comparison with fixed VoIP numbers. However, it’s not all about location and flexibility in working style. Some of the other top benefits include:

  • Increased flexibility. Business calls can be taken from anywhere and on any mobile device—an important point for modern employers and employees seeking increased flexibility in the workplace.
  • Remote work support. Employees can stay connected with each other remotely through platforms like Skype and Zoom.
  • Cost effective. The only fees incurred come from your internet provider.
  • Global location. You can choose where your business is located in the eyes of your customers, regardless of where you live. This makes it easier for your sales staff and other traveling employees to approach customers on an international scale.
  • More features. You’ll have the ability to initiate conference calls, record calls, and queue callers following an automated voice recording.
  • Increased reliability. A traditional phone line network can have a sporadic connection, depending on the line quality.

This feeds into the challenges that come with a non-fixed VoIP, including:

  • Less professional. Your VoIP number won’t be linked with a fixed location, so it’s not easily identifiable with caller ID. This may come across as unprofessional when customers and clients don’t associate your business with an incoming call. (There is an exception to this, which we’ll explain below.)
  • Not as secure. It’s easy for scammers to operate using non-fixed VoIP numbers, since they’re not linked with physical locations and can’t be traced easily. This makes consumers wary of non-fixed VoIP numbers and could be damaging to your business’s reputation if your number is spoofed.

Other notable features about non-fixed VoIP numbers

Despite operating without a physical location link, it is possible to trace non-fixed VoIP numbers—one of the main ways being through the use of a very simple caller ID structure, which allows a caller’s name to show up and link with your number. This is one way in which businesses can ensure that their non-fixed VoIP and lack of physical location code doesn’t affect their reliability.

To trace a call from an unknown non-fixed VoIP number, you can use a free number look-up site or contact a mobile phone carrier to ask for the caller’s details.

And finally, it’s important to note that chat and text messaging can be enabled with both fixed and non-fixed VoIP numbers, allowing VoIP to support business operations across all levels and business scales.
