What is non-fixed VoIP and what is fixed VoIP? Voice over Internet Protocol (VoIP) is a technology that allows you to make phone calls over the internet. Many different companies offer VoIP, but the type of VoIP offered differs across companies. Generally speaking, there are two different types of VoIP: fixed and non-fixed voip. Here are some of the important differences you should know:

Identification necessary for sign up

The biggest difference between fixed voip and non-fixed VoIP is that fixed VoIP requires that you tie a certain address to the number, similar to a regular phone provider. Non-fixed VoIP is a type of VoIP that is commonly used by providers, such as Sype and Google Voice. Kenney Trinh, the editor of a gadget review publication, says, “Non-Fixed VoIP allows calling worldwide numbers with a lot of anonymity. You don't need to enter your address, all you have to do is sign up like signing up to any online service without a lot of personal information. Your address isn't tied to your account.”

Phone number assignment

Another difference is the number that you are assigned and the number that you call from. Chelsea Brown, the CEO of Digital Mom Talk, clarified that, “A fixed VoIP phone number doesn't change whenever you make a phone call. It stays the same and is ideal for companies that need to keep the same phone number. When your number isn't fixed, you can change it as you please. This is ideal when individuals need burner phone numbers.”

The price paid


For fixed VoIP, it is generally provided by a specific VoIP provider, and you have to pay these companies a yearly or monthly fee. Non-fixed VoIP, however, are commonly issued by providers that offer them for free. This gives you the ability to talk to virtually anyone in the world, free of charge.

The bottom line

Generally speaking, fixed VoIP phone numbers are more well respected because they are less likely to be used by scammers. However, this doesn't mean that reputable companies do not use non-fixed VoIP. If your company needs to have a number that originates from a different location than where you are located or if you need to switch your number often, non-fixed VoIP is a good choice. It is also a good choice for those who have less money to spend on the numbers and are not too worried about having a completely legitimate phone number. Fixed VoIP however, is more for companies that are looking for a permanent phone number that they can use to contact customers. They are legitimate and are a great subsitute for a normal land line.
