By | Susy Richards

Have you decided that you should get VoIP? Great! With this switch, you would be able to:

  • Get rid of clunky telephone lines
  • Scale up or scale down easily
  • Modernize your business
  • Lower current fees you pay for communication

There are a lot more advantages that come with getting VoIP from companies like But what you may not have decided yet is whether you should get the fixed or non-fixed version. So here, we’ll provide you information on these two so you can decide for yourself.

Fixed Voice over Internet Protocol (Fixed VoIP)

Fixed Voice over Internet Protocol (Fixed VoIP) is the kind of VoIP where there is an associated real physical location to it. This doesn’t mean that it’s not an internet phone anymore. But for you to have a number from a certain place, you need to prove that you actually have either an office or home address there.

So for you to be qualified for fixed VoIP, you need to submit additional details like the name of the account owner (which can be a person or a company) and proof of address.


  • It gives your company more credibility. Because there are certain requirements to get this, scammers don’t usually use fixed VoIP.
  • It can be used for office and residential purposes. Even if you don’t get the whole system, you can still benefit from this service.
  • The chances of someone stealing your number are much lower. To obtain a number through fixed VoIP, you would need to buy your own cables. That makes it harder for anyone to pretend to be you or to represent your company.



  • It’s more costly. You’ll need to have additional equipment before you can use fixed VoIP.
  • The application takes longer to process. So you need to plan buying this way before you’d need it.
  • You may need to pay extra if you make an offshore call. This means your bill would be higher if you always contact numbers outside your country.

Non-Fixed Voice over Internet Protocol (Non-fixed VoIP)

Also called by others a virtual phone number, your non-fixed VoIP doesn’t ask you to give proof of location to get one. This means you can get a number even from the opposite side of the world.


  • It’s easier to get. There are less requirements, so you can start using it right away.
  • It’s cheaper. You don’t need any additional equipment, which means less money that have to be spent.
  • You can assume a number from a different country to yours. This means you can serve clients from any part of the world.
  • It’s great for businessmen who travel a lot. You’ll be able to avoid high roaming fees while maintaining constant communication with your business.


  • It’s usually used for fraud and scams. So the person would be less likely to trust you. Depending on why you called, this can be bad for business.
  • Your number can be used for fraud. Once you get rid of a number, it will be up in the market again. So if someone wants to, they can pretend to be you.

What can you do with both fixed VoIP and its non-fixed counterpart?

No matter what you get, you will still be able to:

  • Call people with your internet connection as the medium.
  • Benefit from lower costs of communicating with other people.
  • Use your existing gadgets like laptop and smartphone to call.
  • Activate receiving and sending text messages.

What should you have for your business?

questionThere’s no right answer here. What you’ll need will depend on your needs. So here are a few things you should consider:

Type of business

Off-shore call centers would most likely gravitate to non-fixed VoIP because they’re usually calling people from other countries. But if most of your clients are local, the fixed counterpart may be more beneficial.

Employee location

If you rely heavily on offshore labor, you might need the employees to have an address from the same location. You may want to appear that the calls are coming from a certain area, which non-fixed VoIP makes possible.

Cost considerations

Fixed VoIP is always the more expensive option, everything else held constant. So if you’re concerned about lowering communication costs, it’s your better option.

VoIP use

Internal communication may be more of a concern if most of your clients contact you via email. If this is the case, it wouldn’t make sense to spend more through fixed VoIP when the alternative already does the job.

No matter what you choose, what we’re sure of is VoIP is always the smarter option. Do you remember how internet connectivity used to be expensive? And now, it isn’t.

The Internet (for both mobile data and wired connection) will only become cheaper in the future, while wired phones will be obsolete. So if you want modern and cheaper messaging modes, now’s the right time to switch the VoIP.
