Non-Fixed VoIP

What does Non-Fixed VoIP Mean?

Non-fixed VoIP systems, most commonly known as virtual numbers, are phone lines that aren’t linked to physical addresses. They’re cloud-based systems that are assigned to an individual user.


Both fixed and non-fixed VoIP offer the same features and are used for both business and residential purposes. However, the latter is particularly useful for companies with international customers.

With a non-fixed VoIP, you can get numbers for areas where you don’t have a physical presence. These can then be assigned to devices like VoIP phones, computers, cell phones, and tablets.

Fixed VoIP vs Non-Fixed VoIP — The Key Differences

The fundamental difference between non-fixed and fixed VoIP is that the latter requires a physical address, such as a work or home address. So, while both require an internet connection and decent internet speeds, non-fixed VoIP isn’t tied to a physical location.

Fixed VoIP numbers are connected to PSTN through a SIP network, and while the same is true for non-fixed numbers, they don’t completely rely on them. Instead, they’re solely dependent on the internet, making it a cheaper option.

On the other hand, fixed VoIP can be expensive since it uses location-based services and requires physical infrastructure. Overall, fixed VoIP requires a lot more to set up.

Fixed VoIP Pros and Cons

Here are the main advantages and disadvantages of fixed VoIP solutions:


  • Offers easy access to emergency services
  • Offers advanced features like audio and videoconferencing
  • Builds trust and reduces scams as numbers are traceable
  • Caller ID makes it easy for customers to recognize your number


  • On-the-go usage isn’t possible as a physical location is required
  • Requires a more advanced and expensive setup

Non-Fixed VoIP Pros and Cons

Here are the upsides and downsides of having a non VoIP solution:


  • Lower costs for long-distance and international calls
  • More flexible as it’s not tied to geographic location
  • Doesn’t require a physical installation
  • You can easily connect with customers worldwide


  • Requires a stable internet connection
  • Scammers prefer to use non-fixed VoIP solutions

The Bottom Line

To conclude, fixed VoIP is perfect if you want a consistent communication system. It’s ideal for businesses, offices, and homes looking for a reliable and permanent phone service.

On the other hand, opt for non-fixed VoIP if you want flexibility and mobility. These services are ideal for travelers, growing businesses, or remote workers looking to make calls on the go.
