When doing your search on Voice over Internet Protocol (VoIP) in the business phone system space, you would have probably stumbled across fixed and non-fixed VoIP.

While that may sound confusing, it’s actually much simpler than you think!

In an earlier article about non-fixed VoIP, we explained that non-fixed VoIP numbers refer to virtual phone numbers that are not limited to any geographic location.

Non-fixed VoIP numbers are not tied to any device either. You can make calls using computers, mobile phones, and tablets — as long as you have an internet connection.

So what about fixed VoIP then? Let’s dive deeper into what fixed VoIP is and what it means! 🏊‍♂️👇


What is fixed VoIP?

Fixed VoIP refers to a phone number attached to a physical address. While both fixed and non-fixed VoIP connect your phone through the internet, a fixed phone number requires a physical address, similar to a traditional phone line.

This can make fixed VoIP a more preferred choice to some businesses as you have a local phone number. This makes you seem more credible to customers when you’re doing business locally and make local cold calls.

Furthermore, because fixed VoIP numbers are tied to a real address, calls can easily be tracked.

These reasons typically make fixed VoIP numbers more secure than non-fixed VoIP.

Benefits of fixed VoIP numbers


As we mentioned earlier, fixed VoIP numbers are easily trackable because they’re tied to a physical address. This could be your residential or business address.

Fixed VoIP numbers are also highly likely assigned by VoIP providers whose broadband network connects to the public switched telephone network (PSTN). What this means is that these carriers typically own the network in which your calls are transmitted over and hence, require strict security protocols to prevent your numbers from being hacked or spied on.

On the other hand, non-fixed VoIP numbers aren’t associated with any address and are thus widely used by spammers for international scam calls and impersonation calls.


Have you ever received a call from a number with a different area or country code and you just knew that it was a spam call? After all, foreign numbers and dialing codes would definitely raise our suspicions on who would be calling our phones.

Once again, because fixed VoIP numbers need to have a physical address, this means that you have a local business phone number with a local country code.

This provides a sense of authenticity and credibility when making calls to local customers.

More reliable during emergencies

When you make calls using a non-fixed VoIP number, your calls can’t be traced back to the location of the call.

But for fixed VoIP numbers, calls can easily be traced to a specific location.

When you dial for emergency services, operators are able to immediately pinpoint the exact location of your call and can quickly dispatch the right team to you. This will speed up the rescue process and in dire times, can be a life saver.

Should you use fixed or non-fixed VoiP?

Now that you know what fixed VoIP is, let’s take a look at some deciding factors to help you choose which you should use for your business.

If you’re a global team:

Without a doubt, any business with remote teams around different parts of the world should use non-fixed VoIP numbers for their corporate calling needs.

It’s a cost-saver and the easy administration of a VoIP phone system makes it great for both managers and team members alike to improve their daily workflows.

If you rely on cold calling:

If your team makes frequent calls to prospects and leads out of your region, you should definitely use non-fixed VoIP numbers. The affordable international calling rates of non-fixed VoIP numbers are not to be missed!

Potential customers that you’re reaching out to will also be worry-free from any international charges when they pick up your call, because you’ll most likely be reaching them with your region-specific non-fixed VoIP number! 😉

If you’re on a tight budget:

Definitely non-fixed VoIP!

Fixed VoIP numbers are usually charged on a monthly or yearly basis, and this doesn’t include international call charges. And more often than not, international calling fees can rake up your costs.

So if you’re going to be making many calls, fixed VoIP can put a strain on your finances.
