As we’ve shared before, VoIP phone services let you phone calls through an internet connection instead of a landline. Within VoIP, there are a number of solutions for different kinds of businesses. One term you may see coming up when researching business phone services are fixed VoIP and non-fixed VoIP. Here, we’ll explain the difference between fixed and non-fixed numbers and why we recommend a fixed number.

What’s the Difference?

Fixed VoIP

While both types of numbers connect your phones through the internet, a fixed phone number requires a physical address. That means to have a local phone number, you need to have a location based in that same country. For most businesses, a fixed number is both preferred and offers a competitive benefit. It shows local customers that you’re an authentic company.

Perhaps most importantly, a fixed number can be tracked. For instance, if someone dials an emergency services number like 911, they will be able to tell where the call came from. Trackable numbers are harder to abandon and provide a sense of legitimacy.

While a fixed number is linked to an address, you can take the number with you should you ever need to move locations.

Non-Fixed VoIP

As you may have deduced, a non-fixed phone number does not require a physical location. They are easier to obtain using an online calling service like Skype. Historically, non-fixed numbers went through fewer security protocols, which is why they were the top choice for fraud companies. If you’ve ever had your cell phone ring with a “scam likely” robocall, there’s a good chance it came from a non-fixed VoIP number.

With a virtual phone number, you can assign any area code to your phone number. If a company is based in New York City but does a lot of work with Chicago clients, they may want to have a line with a Chicago area code to give the impression of a local presence – even if they aren’t actually located there. This often triggers scam alerts as it is also a common tactic for fraud. Scammers will copy the first 6 digits of a number to something that will seem familiar on your caller ID so that you’re more likely to pick up.

Today, there are systems in place that make non-fixed number users a more secure choice than they used to be.  Plus, when combined with an in-house PBX system, a non-fixed system may be a cheaper option for companies located in more than one country. But, non-fixed numbers are still relatively disposable and more likely to trigger spam filters.

Effect on Long Distance Calling

The biggest benefit of non-fixed number is the ability to use services like Google Voice and Skype for calling, cutting down long distance costs. International calling through VoIP (voice over internet protocol) can cost more than domestic calls because of the associated regulation fees. However, these long distance calls will still be cheaper than if they were made through landline connections.

Non-fixed calling is still more common for personal use, as you only need an email address to sign up. However, business VoIP providers that use fixed numbers will offer more features that companies need when calling internationally.
