    Are you tired of reading tons of articles about non-fixed VoIP filled with technical terminologies as dry as dust? Well, here is the only VoIP guide you need – clear and straight to the point with crucial information for understanding why a non-fixed VoIP system will work best for your business.

    How Does VoIP Work?

    Voice over Internet Protocol (VoIP) is a technology that allows you to make phone calls online instead of using a traditional landline or mobile signal. 

    Simply put, during a VoIP call, your device digitizes your voice picked up by the microphone and transmits it over the Internet. The data is then unpacked and transformed back into audible sound on the recipient’s end. Rinse and repeat, and you’re talking just like you would on a regular phone call.  

    VoIP doesn’t require any special equipment. All you need is a stable internet connection and a device with a microphone As such, it’s a flexible and cost-effective solution used by a growing number of companies around the world.

    Fixed vs. Non-fixed VoIP Numbers

    Before you choose a VoIP number, you should consider several factors. One important distinction is whether the number will be fixed or non-fixed. What’s the difference, and which one should you choose for your business? Let’s take a closer look.

    #1 Fixed VoIP Numbers

    A fixed VoIP number is tied to a specific location, usually a physical address, much like a traditional phone line. That means you have to be based in the same country to get a local number.

    Don’t worry, though. This is still an Internet-based number, just one assigned by a telecom provider connected to the public telephone network (PSTN).

    #2 Non-fixed VoIP Numbers

    A non-fixed VoIP number isn’t tied to a physical location. This means that you can assign any area code to your phone number. Because these numbers are much easier to obtain, they were infamous for being unsecured and used primarily for phishing. These days, that’s far from the truth.

    Today, there are systems in place that allow non-fixed numbers to be safe and secure. Therefore, they are ideal for large businesses that wish to have a local presence in multiple areas to obtain a non-fixed VoIP number. 

    Let’s suppose that your company has customers in various locations around the world. Thanks to this piece of VoIP technology, you can use many different area codes even if all calls are made from one place.

    Non-fixed VoIP numbers are the key to giving your business an authentic local presence, even if you’re not located in that particular area.

    What Are the Main Differences?


    These two types differ primarily in availability and flexibility. A fixed VoIP number is permanently assigned to a single address, creating limits on where it can be used. On the other hand, a non-fixed VoIP number can be associated with any device that has a compatible VoIP app installed (such as CloudTalk). This means that you could use your PC at home to make calls with your business’s non-fixed VoIP number.

    Price of International Calls

    Fixed and non-fixed numbers differ in price. International calls are much more expensive with the former, whereas they are nearly free when using the latter.

    Area Codes

    As mentioned before, fixed numbers have a local area code assigned to an address. This limits you if you want to operate as an authentic company in several countries.


    With a fixed VoIP number, you can rest assured that the contact information in your phone number will remain private. Nevertheless, It’s worth noting that the security of non-fixed numbers has improved considerably and no longer deviates from any safety standards. Solutions like CloudTalk are one of the safest ways of making VoIP calls today.


    To sum up, non-fixed numbers are a much better option for growing businesses that operate from multiple locations and/or still want to expand their activities to new locations.

    The Pros and Cons of Non-fixed VoIP

    Pros of a Non-fixed VoIP Phone System:

    #1 When it comes to international communication, non-fixed VoIP numbers are the better choice. Connecting with others worldwide is easy and almost completely free of charge with providers such as CloudTalk.

    #2 Non-fixed VoIP numbers support businesses with global expansion. Area codes are not restricted to a physical address, so you can easily set up a reliable international support center for your company. This type of VoIP number allows you to reach your customers and prospects using area codes they are familiar with.

    #3 Mobility and flexibility. Non-fixed VoIP numbers allow your agents to make calls from wherever they are, even their homes or own devices. You only need to cover price of a softphone app and make sure your device supports VoIP. With the top phone system for remote workers, it just became even easier.

    #4 Non-fixed VoIP numbers are easy to obtain. Usually, all you have to do is register with an email address. This is the case with CloudTalk, for example.

    #5 Non-fixed VoIP lines are generally much cheaper than fixed ones (or even free).

    ⛔️ Cons of a Non-fixed VoIP Phone System: 

    There is just one: there is a chance the calls can be fraudulent or spammy. That’s why it’s extremely important to choose a reliable VoIP provider that is compatible with the highest safety standards.

    Also, Non-fixed VoIP numbers are more commonly used for illegal activities (since they are affordable, easy to access, and often hard to trace). As a result, these numbers may appear less authentic and trustworthy.

    Who Should Use A Non-Fixed VoIP?

    Non-fixed VoIP is great for pretty much any business that relies on calls. However, it works best for those that:

    • have mobile or remote employees
    • are in multiple locations within one city or across several cities, countries, and/or continents
    • deal with a lot of international calls
    • experience unpredictable customer demand

    A non-fixed VoIP gives these companies the flexibility to make and receive calls from anywhere at any time without the need for expensive and complex equipment. That’s the sort of convenience they’re looking for. 

    It’s the ideal solution for:

    Support Centers

    Often, these types of companies provide services in many different languages. They need to have a large number of customer service representatives on staff, which can be expensive. With non-fixed VoIPs, they can employ people in different countries to take calls in their native languages, cutting down on support costs.

    However, even if they operate from one location, they will still be able to assign individual area codes to each agent. This is something that’s not possible with a fixed phone system.

    Sales Teams

    A non-fixed VoIP is perfect for sales teams, as they can make and receive calls from anywhere. This is especially useful for companies with employees in different time zones because they can still make calls outside of the local business hours. Furthermore, with features like call recording and integration with a CRM system, your sales teams will never miss an opportunity to acquire a new lead.

    Multi-location Businesses

    If your company has multiple locations, non-fixed VoIP can help you save on long-distance and international calls. With this type of system, you can connect all of your locations with one central VoIP system and make calls between them at a fraction of the cost of traditional phone lines.

    E-commerce and Retail

    These businesses need to be able to handle high volumes of calls, which a non-fixed VoIP system can help them do. They can also take advantage of features like automatic call distribution to make sure they’re always available to their customers.


    Companies that rely heavily on this ever-changing environment require a VoIP solution that can keep up with their needs. A non-fixed VoIP number can do just that, and they are also scalable to grow with the company.

    7 Best Practices for Using Non-fixed VoIP

    #1 Make Sure Your Internet Connection Is Up to the Task

    If you plan on using a non-fixed VoIP service, check that your Internet connection is strong and stable. You’ll need a high-speed broadband connection with enough bandwidth to support VoIP traffic.

    Test it out by doing a speed test. If you don’t get the desired results, you may need to upgrade your service. Apart from this, you should also have a power backup in place, as VoIP won’t work without electricity.

    #2 Use a Quality VoIP Service

    The VoIP market is crowded with a variety of providers. Do your research and choose a quality service that meets your needs. Ask people from your industry, business partners, or even family and friends for recommendations.

    When you’ve found a VoIP provider that you’re interested in, check out reviews online to get an idea of what other users think.

    What should you look for? Here are a few things to consider:

    • Can you count on the service to be up and running when you need it? The reliability factor concerns whether or not a particular solution will be able to provide the desired results when it’s needed most – during an emergency situation when time is critical and every second counts.
    • The provider should offer good customer support. You don’t want to be left alone in the dark if something goes wrong.
    • It should have all of the features that you want. Don’t compromise, even for a lower price. If the provider offers advanced features that are polished and work great, this means their service is probably worth the money, and you won’t be frustrated by its limitations at any point.
    • Ensure that the provider uses the most up-to-date security protocols to protect your data and calls.
    • Is the service affordable? Does it offer a free trial? After all, you don’t want to buy a cat in a bag.
