    Non-Fixed VoIP: What It Is & Why You Should Care

    One in three employees work remotely. And as the remote trend continues to grow, so does VoIP adoption. Nowadays, 31% of companies use VoIP. But which one should you choose?

    In this article, we’ll help you kick-start your VoIP buying journey by breaking down the two main types – fixed and non-fixed VoIP. We’ll also share a few best practices and end with a recommendation for the most suitable software for you. 

    Key Takeaways:

    • The main difference between fixed and non-fixed VoIP is that the former is tied to a single person and location, while the latter is not.
    • Non-fixed VoIP numbers can be used to make and receive calls all around the world, making them a great choice for remote teams.
    • Overall, non-fixed VoIP is more affordable, flexible, and scalable and offers numerous AI-powered features and 3rd party integrations.

    What Is Non-Fixed VoIP?

    Non-fixed VoIP refers to a type of call center system that isn’t tied to a single physical location. That means that non-fixed VoIP users can make and receive calls in numerous foreign countries without having to be there in person or owning a local business.

    Because of this, most (if not all) international companies use non-fixed VoIP software for their call center operations. This allows them to expand their global sales operations and offer high-quality customer service without having to build an office in every country.

    What Is a Non-Fixed VoIP Number?

    Generally speaking, a non-fixed VoIP phone number can be any kind of virtual number. In practice, that means they can be used by several employees across multiple locations, as opposed to fixed VoIP numbers which are tied to a single person and place.

    Non-fixed local, toll-free, and international numbers are affordable from VoIP providers such as CloudTalk. Often, you’ll even receive one completely free with your subscription.

    Non-fixed VoIP works equally well for both sales and support and is used by companies in various industries. However, E-commerce, Retail, IT, and SaaS companies are some of the most common customers.

    7 Best Practices for Using Non-fixed VoIP

    Setting up your non-fixed VoIP, requires a little extra work. Below, we’ll cover the main things you should keep an eye on to ensure you have the best possible experience. The 7 best practices include:

    #1 Get a Stable Internet Connection

    The quality of your non-fixed VoIP wholly relies on your Internet connection. Test your speed and bandwidth, and if it seems insufficient, consider upgrading your service. You may also want to get a power backup for potential blackouts.

    #2 Choose a Quality VoIP Provider

    Providers influence numerous aspects of your VoIP, including number, feature, and integration selection, pricing, security options, and more. Research and choose a reputable provider to get the best experience.

    #3 Save Time with Features

    Call center software offers numerous features, such as click-to-call, sales dialers, and more, that can help you automate, streamline, and improve your processes. Choose a pricing plan that meets your needs and put them to use.

    #4 Train Your Employees

    A tool is only as good as the person using it. When implementing non-fixed VoIP call center software, make sure to properly onboard and train your employees so they know how to make and record calls and evaluate their performance.

    #5 Test Your System Before Going Live

    Testing is often overlooked during the set-up process, but it’s in your best interest to have everything working at full capacity when you hit “call.” Use your provider’s free trial to ensure the solution works well for you.

    #6 Keep the Software Up to Date

    As with any software solution, non-fixed VoIP systems also often receive updates and bug fixes. Make sure all your employees update the software on all their devices to ensure a stable and expedient experience.

    #7 Monitor Performance

    Most good VoIP solutions come with an Analytics feature that allows you to monitor efficiency at an agent, team, department, or organization level. Use it to fix issues, remove bottlenecks, and improve overall performance.


    Making an unlimited number of affordable calls to and from anywhere in the world is key to unlocking your business’s growth potential and staying competitively viable, especially when combined with AI-powered features and third-party integrations.

    Don’t let landlines and borders limit your business. Make the switch.
