What is Non-Fixed VoIP: Benefits & Features for Businesses

How we communicate has fundamentally transformed, with increasing numbers of businesses and individuals turning to Voice Over Internet Protocol (VoIP) solutions. Specifically, non-fixed VoIP offers more flexibility and cost-effectiveness that traditional phone systems simply cannot match.

Did you know that over 31% of companies have already integrated some form of VoIP into their communication strategy? This technology not only allows for a more mobile workforce but also significantly reduces operational costs.


So if you’re running a startup or a large corporation, understanding how Non-Fixed VoIP can support your needs is crucial. In this comprehensive guide, we will guide you through the essential aspects of a Non-Fixed VoIP number, including its benefits features, and use cases that can enhance your business calling operation.

What is Non-Fixed VoIP 

Non-Fixed VoIP, often called ‘virtual phone numbers‘ or “nomadic VoIP”, is a communication technology that does not require a fixed physical location to operate effectively. 

Unlike traditional telephony which depends on physical lines or Fixed VoIP which operates only from a specific place, non-fixed VoIP lets you route calls over the Internet from any location. 

This means you can make and receive calls using a high-speed internet connection from your smartphone, tablet, laptop, or desktop,  avoiding the need for traditional telephone infrastructure. 

The flexibility of non-fixed VoIP systems enables you to communicate continuously across regions, making it an essential tool for your business operating globally. 

How does Non-fixed VoIP work 

You might be having this question exactly how does non-fixed VoIP function and what makes it so unique compared to traditional phone systems? 

Essentially, non-fixed VoIP operates by converting your voice into digital signals. The term digital signals means that your voice is transformed into a format that can be sent and received over digital networks rather than through copper wires or other traditional telephony infrastructure. 


When you use a device that’s capable of VoIP communication, such as a smartphone, tablet, laptop, or even a desktop, your voice is immediately transformed into data packets. These packets travel across the internet to reach the recipient on the other end of the conversation.

At the receiving end, these data packets are converted back into audio signals (just like normal voice) that the recipient’s device plays back, allowing them to hear your voice as if you were using a traditional phone line.

Key features of Non-fixed VoIP

Non-fixed VoIP offers several features that make it a better option for your business:


1/ Call Forwarding

This feature allows calls made to your number to be forwarded to another phone number or device of your choice.

It means if someone calls you, and you’re not able to answer on your primary device, the call can be sent to another device, ensuring you don’t miss important calls.

This is particularly useful for business professionals who are often traveling or working from different locations.

2/ Call Waiting

If you’re already on a call and someone else tries to reach you. Instead of getting a busy signal, Call Waiting lets you know there’s another call waiting for your attention.

You have the flexibility to place your current call on hold and switch to the new call. This way, you won’t miss out on calls even when you’re already engaged in a conversation. 

3/ Auto-Attendant (IVR) Systems

The Auto-Attendant of non-fixed VoIP is like a virtual receptionist for your business. When someone calls your number, this system can greet them with a recorded message and give them options. For example, “Press 1 for Sales, Press 2 for Support,” and so on.

This way, callers get directed to the right department without needing a real person to answer every time. It helps your business look professional and keeps things organized, making sure every caller gets the help they need efficiently.

4/ Customized Voicemail

Customized Voicemail lets you create your voice message for a caller when you can’t pick up the phone. For example, a customized voicemail may sound like, “Sorry, I can’t talk right now, but please leave a message!

This way, people can leave you a message, and you can get back to them when you’re free. It’s a great way to make sure you don’t miss out on anything important, and it lets people know you’ll call them back as soon as you can.

5/ Number Portability:

The feature of Number Portability refers to the capability to retain your existing phone number when switching from one service provider to another or when changing your physical location.

This feature is crucial for maintaining continuity in communication and ensuring that contacts can reach you without the need to update them with a new number.

It serves as a valuable tool for businesses and individuals who require a stable and consistent point of contact, regardless of changes in their service provider or geographical location.

6/ Enhanced Functionality

Beyond these features, non-fixed VoIP offers enhanced functionality that traditional phone systems simply cannot match.

This includes video conferencing, instant messaging, file sharing, and integration with other digital platforms, providing a complete communication solution that adapts to the modern business environment.

Why would you use a Non-fixed VoIP number? 

There can be many reasons for getting a non-fixed VoIP number. Most specifically it is ideal for those who value flexibility and mobility in their communication needs.

These numbers are also cost-effective, reducing the need for costly traditional phone lines or expensive mobile plans. Plus, they offer the convenience of easy setup without the need for a physical location.

Below we will discuss some of the key benefits of using Non-Fixed VoIP numbers for your communication needs. 

Advantages of Non-fixed VoIP for your business 

1/ Cost Efficiency:

The first compelling reason for you to consider using non-fixed VoIP technology within your business is the considerable cost savings it provides. In fact, according to Nextive businesses can reduce their phone cost by 50% by utilizing VoIP, especially if you compare it with traditional phone services

On the other side, as we discussed above non-fixed VoIP operates over the Internet. This means you can make calls, including international ones, at a much cheaper cost compared to traditional phone lines.

Additionally, many of the advanced features that come standard with non-fixed VoIP systems, such as auto-attendant, call forwarding, and customized voicemail, are included at no extra charge. 

2/ Improve scalability in operation:

The scalability aspect of non-fixed VoIP technology allows your business to easily adjust its communication capacity based on current needs.

This means you can add or remove lines, features, and services as your business grows or as demands change, without undergoing a complex and costly upgrade of your communication infrastructure. 

3/ Integration with Business Tools:

Integrating non-fixed VoIP into your business’s existing tools and software platforms enhances operational efficiency. This integration capability means your VoIP system can work perfectly with customer relationship management (CRM) systems, email platforms, and productivity applications.

For instance, when a call comes in, your CRM can automatically display the caller’s information, providing valuable context for the interaction.

This integration between VoIP and other business tools streamlines workflows reduces the need for manual data entry, and enhances customer service by offering a more personalized and informed interaction.

4/ Global Reach at Local Rates

The ability to communicate globally at local rates is another significant advantage of adopting non-fixed VoIP technology for your business.

This feature is especially beneficial for businesses with a global client base or those looking to expand into international markets.

By utilizing non-fixed VoIP, companies can maintain constant communication with overseas clients, partners, and remote employees without incurring the substantial charges typically associated with long-distance calls.

5/ Enhanced Customer Experience:

Offering a better experience to your customers can be achieved with non-fixed VoIP due to its variety of features. Essentially, this technology lets you easily manage calls, ensuring that every customer can quickly connect with the appropriate team member.

Features like auto-attendant mean your customers are not left waiting; they are directed immediately to where they need to be. Furthermore, because you can integrate VoIP with other business systems, customer information can appear automatically during calls. This allows for a more personalized conversation, making customers feel understood and valued.

Consideration and potential drawbacks of Non-fixed VoIP

1/ Dependence on Internet Connection:

One crucial aspect to consider with non-fixed VoIP is its dependence on your stable internet connection. Since all communication occurs over the Internet, the quality of your calls directly correlates with the speed and reliability of your Internet service.

If your business experiences frequent internet downtime or bandwidth limitations, this could lead to dropped calls, poor audio quality, and delays in message delivery. 

2/ Security Vulnerabilities:

Another critical consideration is the security vulnerabilities associated with non-fixed VoIP services. Since your communications are conveyed over the internet, they are naturally at a greater risk of interception, eavesdropping, and cyber-attacks compared to traditional, hard-wired phone systems. 

3/ Emergency Calls Limitation

Non-fixed VoIP services do not automatically provide a fixed physical location to emergency service operators when a 911 call is made. This limitation means that in the event of an emergency, you or your employees need to verbally communicate your location to the responders, which could delay the response time during critical situations.

Therefore, ensuring your business has a plan in place for accurately and efficiently communicating location information during emergency calls is essential.
