A non-fixed voip phone number is not linked to a physical address. It is also known as a virtual phone number. Like VoIP landline numbers, it can be used as a residential or business phone number, but rarely replaces the entire phone system. Such numbers are also known as "virtual phone numbers" and are often issued by free services such as Skype and Google Voice. They rarely require anything more than an email registration and perhaps some payment information if relevant, although access to these platforms tends to be free of charge. A landline number does not require a physical location.
They are easier to obtain using an online calling service such as Skype. Historically, landline numbers went through fewer security protocols, so they were the primary choice for fraud companies. If you've ever had your mobile phone ring with a robotic "likely scam" call, chances are it's coming from a non-fixed voip number. Non-fixed lines do not need to be linked to a physical address, unlike fixed voip numbers. Instead, these lines are associated with a general geographic location. Moreover, the owner of a VoIP account does not even have to work or live in the area where the line is associated.
In short, landline VoIP phone numbers are associated with the physical address of the account holder, while non-fixed voip numbers are not tied to any specific address. One of the terms you may see pop up when researching business phone services is fixed VoIP and non-fixed VoIP. The distinction bloggers make between fixed and non-fixed VoIP phone numbers is tenuous at best. With respect to VoIP service providers, there are generally two types of VoIP services, fixed and non-fixed. In turn, VoIP providers are more likely to support 911 calls and emergency services on fixed VoIP lines versus non-fixed ones, which have no address on file where first responders can be dispatched. Because they are so affordable, easily accessible and often difficult to trace, non-fixed VoIP numbers are more disposable than a fixed VoIP number and are more frequently used for criminal activity; more on this shortly.
Also, it is now possible to identify non-fixed VoIP calls and text messages on the basis that the number is linked to a non-fixed VoIP service when retrieving caller ID information. Conversely, non-fixed VoIP numbers can be useful when simply looking to create a quick line that can be used for personal calls, call forwarding capabilities, or to make international calls that might be more expensive to make over a fixed VoIP line. With the exception of the e911 services mentioned above, the features offered by a provider, such as voicemail, call forwarding, conferencing, personalised greetings, incoming call handling and more are available through fixed and non-fixed VoIP number services alike. The difference between fixed and non-fixed VoIP numbers is not particularly complex, although it may not be readily apparent to someone who does not fully understand Voice over Internet Protocol. The pros and cons of fixed and non-fixed VoIP numbers range from one being more secure and reputable to the other being easier to set up and offering greater flexibility.
