Step-by-Step: Fixed VoIP vs. Non-Fixed VoIP

As of April 2020, approximately 66% of all U.S. employees worked remotely at least one day a week.

It has become more critical than ever for employers to invest in communication services during the pandemic we currently face.

Many people fear for their health and safety at work, and not working from home will put them at risk of infection each day.

Allowing employees to work remotely can provide many benefits to the company as well.

Your workers will be less stressed, and you can reduce rent and property costs.

You will have the opportunity to create new jobs and help your employees develop their technical skills. Overall, there are a lot of reasons to consider cultivating a remote sector for your company.

One of the most crucial parts of working from home is communication.

Businesses will need to invest in some form of communication services to instigate a supportive and connected work environment that facilitates collaboration.

A typical service that many people look into is VoIP, or voice over internet protocol.

What is VoIP?

Without knowing it, you have probably used some form of VoIP (Voice Over Internet Protocol) before.

Whether you called a relative on Skype, had a conference call on Zoom, or talked to someone internationally through WhatsApp, you experienced this cloud-based communication.

VoIP works by connecting directly through your WiFi network. There are no cables required, and it can be used anywhere with internet access.

You can make audio or video calls and send and picture text messages. You can even send faxes!

VoIPs are accessible on phones, laptops, PCs, and tablets. All you need is a WiFi connection, and you are good to go.

One reason to switch to VoIP is the lowered costs.

Cell phones and landlines require phone plans, and the bills can stack up depending on the features you add, like data, minutes, international calls, and more.

Many VoIP services offer free voice calls as long as you have internet access.

The voice over internet protocol transmits your phone call over the internet quickly to expedite the communication process.

However, there are two main branches of this: Fixed VoIP vs. Non-Fixed VoIP. What is the difference between fixed and non-fixed VoIP? Read on to find out.

What Is a Fixed VoIP?

You have probably been wondering, “What is the fixed VoIP meaning?”

A fixed VoIP is an internet-based phone line corresponding to a specific physical address. You can utilize fixed VoIP commercially, industrially, or residentially.

If you install the fixed VoIP in your office, only people who are associated with your business will have the option to access your network within a particular geographical area.

Most of the time, users will not be able to access the network if they are out of the base country.

It may come as a surprise, but fixed VoIPs retain a degree of portability. If you move, you can update your address within your provider’s system so you will not lose access.

Because of the connection to one address, you will get fewer spam and scam calls. Furthermore, fixed VoIP providers are more likely to support calling emergency services because the first responders will have a location to send dispatch.

Since these phone lines are so regulated, you might have to pay a minimum required tax to make calls.

Many people use fixed VoIP as a replacement for landline services. You can connect it to a physical phone handset, and the features are cheaper, faster, and have stronger connections, assuming you have decent WiFi.

Pros and Cons of a Fixed VoIP Phone

There are several advantages and disadvantages to the fixed VoIP system.


  • More authentic and reliable with fewer opportunities for spam calls
  • They often come with advanced calling and call routing features
  • Dependable emergency services calling because of the associated address
  • A workable replacement for landline phone services
  • Can be set up on many different devices if you authorize the product for the address
  • Fewer criminals use or hack into fixed VoIP systems since they are easier to trace


  • More involved to obtain because it requires an address and other personal data
  • Costs more to acquire because of the additional security and services
  • Typically, taxes are higher on a fixed VoIP system
  • International calls can get expensive, making them unappealing to global businesses
  • International clients will have to pay fees to contact you

What Is a Non-Fixed VoIP?

What is the non-fixed VoIP meaning? Let’s find out.

A non-fixed VoIP is another internet-based phone line, but it does not correspond to a particular address.

Any location in the world can use it, making it completely portable and highly accessible from any device.

The attainability of the non-fixed VoIP makes it an attractive option for international workplaces who frequently need to contact people from around the world.

Non-fixed VoIPs are usable in all countries, even those outside of the provider’s base, but they are not suitable replacements for landline services. They frequently supplement landlines or fixed VoIPs.

While non-fixed VOIPs have some business-friendly features, most users use it for personal reasons rather than professional.

Many providers have free services, and the paid portions are usually cheaper than fixed VoIPs.

Because they do not require an address, non-fixed VoIPs make excellent choices for those who wish to retain privacy.

However, this also makes them attractive to hackers, spammers, and scammers as they can enter any network without a trace.

Why Do Spammers and Cybercriminals Turn to Non-Fixed VoIP?

Since non-fixed VoIPs lack a connection to a physical address, anyone can use them in any country.

Typically, you only need an email confirmation to get a number. Many service providers do not even require payment information.

With all of the fake mail generator websites available, you can quickly generate new non-fixed VoIP numbers and spoof caller ID information.

The anonymity allows anyone to make false phone calls or place orders with stolen payment cards.

A non-fixed VoIP makes it extraordinarily easy to perform bulk dialing through IP telephony systems. It is accessible and affordable to give the system a simple script to play to make spam calls.

Many companies have designed new VoIPs to counteract the spam callers while remaining non-fixed.

For instance, Whitepages developed an API called Pro Phone Solutions so users can identify what kind of number is calling them.

APIs take data points and combine them into a reputation score that ranks the likelihood that a number is spam.

Now, you can more easily identify if a number belongs to a non-fixed VoIP provider, whether by call or text.

You will need to retrieve the caller ID information, from which you can figure out which provider sources them.

What Should I Do If I Need to Trace a Non-Fixed VoIP Number?

You may not want to read this, but here we go.

Since non-fixed VoIP numbers are super challenging to trace, these services can be breeding grounds for cyberbullying, harassment, catfishing, rental fraud, and even your friendly neighborhood Craigslist scammer.

If you have come in contact with an internet troll or serious cybercriminal and need to find out their identity, you are not out of luck.

If the person has committed a crime, you can report their number to the authorities. These professionals may have the means to track down the owner.

Some service providers have unique phone number layouts, so you may find the company searching for the number online. At that point, you can file a complaint to headquarters against the user for violating the acceptable use policy.

To more anonymously connect with individuals, some people post their non-fixed VoIP numbers on social media.

Often you will find people put their WhatsApp numbers in their Facebook bios, for example. If you track down their account, you will have a clue as to who they are.

Many service providers have the option of blocking, so if someone is bothering you, you might be able to prevent them from sending you more messages.

Pros and Cons of a Non-Fixed VoIP

Non-fixed VoIP systems come with several positive and negative aspects.


  • Not bound by a specific address or geographical location
  • Uninvolved to obtain—many exclusively require an email address and password
  • Many free and inexpensive services compared to fixed VoIP
  • Especially useful if you make a lot of international calls
  • The provider needs less information, preserving your privacy in the event of a security breach
  • Lower taxes than fixed VoIP


  • Prone to hackers and cybercriminals due to the anonymity
  • Difficult to trace spams, scams, and hacks
  • Generally considered a disposable number
  • Viewed as unprofessional in a business setting
  • Often unable to make emergency calls since there is no associated location

Uses of Fixed and Non-Fixed VoIPs

Fixed and non-fixed VoIPs each come with their benefits over the other. Neither is inherently better than the other, and different situations will call for separate systems.

What Is a Fixed VoIP Phone Used For?

Large businesses would do best by investing in a fixed VoIP phone system for their company’s communication.

If your company has a lot of information that they want to safeguard, be it personal, financial, or geographical, a fixed VoIP system will keep it secure from outsiders.

Fixed VoIP systems also come in handy if you operate primarily locally. If you mostly make calls within a specific area and seldom globally, you should not need to risk exposing your company information over a non-fixed VoIP.

Also, if you do not plan to expand your business internationally or contact people from around the world, you will save money by switching to fixed VoIP.

However, if you make international calls, you and the person you are contacting may have to pay a pricey fee.

Fixed communications cost more than non-fixed, but they look more professional and have a better reputation.

All in all, they cost less than landline services, so if you have a strong WiFi network, you should consider investing in a fixed VoIP.

Can You Text a Fixed VoIP?

You can text images or messages on a fixed VoIP. Since you can access the network from any approved device, you can send any message you want that your phone, computer, or tablet allows.

In addition to texting, you can place phone, video, and conference calls. Some providers allow you to print or fax through their network as well.

What Is a Non-Fixed VoIP Phone Used For?

A non-fixed VoIP is an excellent choice for users who need to make many international calls.

With a fixed VoIP, your service provider will charge you extra to make such calls, but non-fixed VoIP plans usually include global communications.

Furthermore, a non-fixed VoIP allows you to retain your personal information, making it better for individual use.

You can more comfortably share your number with people knowing that they cannot locate you or discover personal information about you unless you tell them.

Startups may also prefer to use non-fixed VoIPs as their flexibility and cost are more suitable until they build up their customer base and better understand their market.

Young entrepreneurs showing teamwork inside their office.

Because hackers can readily get into a non-fixed VoIP, they should supplement a fixed line or a landline rather than replace it.

You can use the more secure fixed VoIP communications for regular interactions and save the non-fixed VoIP for international contacts.

Speaking of hackers, if you happen to be one, you might want to look into non-fixed VoIPs!

All jokes aside, anonymity prevents non-fixed VoIPs from contacting 911 or other emergency services. First responders cannot trace your number and locate you, unlike through a fixed VoIP, landline, or cell phone.

While non-fixed communication should not be your only form of communication, it is a great option to inexpensively talk to your friends and family from around the world.

Can You Text a Non-Fixed VoIP?

As with a fixed VoIP, you can text on a non-fixed phone line. You can call through audio or video, and host digital conferences as well.

An advantage is the ability to host these conference calls internationally, which works exceptionally well when you have to operate remotely.

A fixed VoIP conference call will also function well remotely, and you can more securely contain the conference in your company. However, it adds the complication of registering the devices within the network.

Should I Get a Fixed or Non-Fixed VoIP?

Base your investment in a fixed or non-fixed VoIP on your personal needs.

If you belong to a company with a lot of private information that you do not want to leak out to the public, a fixed VoIP would be your best bet.

Nevertheless, fixed VoIPs cost more. You usually need to pay for them upfront, and they have higher taxes.

The tradeoff is security within your network. Only approved devices will have access to a number.

People generally view fixed VoIPs as more authentic, reliable, and respectable because of their extensive security measures.

Many providers allow you to make emergency calls, which you cannot say for non-fixed communications.

However, if you do not want to share your payment information and personal data with a service provider, you would not like fixed VoIPs.

In that case, a non-fixed VoIP should be on your radar. You only have to give them an email address, and you have got yourself a new phone number.

You can also make international calls very easily. With a fixed VoIP, you have to pay extra for international messages, so they are preferred for use within a specific region.

Non-fixed VoIPs are easy to obtain and set up, so if you only want to try out a WiFi-based phone number, you can do so without committing to most non-fixed communications.

No matter what, there is probably a VoIP service provider that will meet your needs. You need to assess what you want out of the company and what you are willing to give.

Be prepared to give away your personal, financial, and household information to a fixed VoIP provider. While more difficult to compromise, in the event that it happens, there is a chance of your data getting leaked.

However, keeping this information to yourself, like with a non-fixed VoIP, will put you at a greater risk of contact with fraudsters who may try and weasel your personal data out of you.

You will have to be smart about who you speak to and what you say on one of these services.

At the end of the day, neither are inherently better than the other, and each has its advantages and disadvantages.

As long as you are aware of the risks and benefits associated with each, you can have an excellent experience on either VoIP option.
