What does fixed VoIP mean

Fixed VoIP is a type of VoIP that assigns a telephone number to a physical address. This feature makes it more authentic and reliable than traditional VoIP systems.

Fixed VoIP works just like any other VoIP service, using the internet to transmit voice calls instead of traditional phone lines. When making a call, voice data is sent over the internet to the recipient’s phone number through a VoIP service provider. 

Fixed VoIP uses a physical address for the location of the service, which can be used to verify the caller’s location and enable emergency responders to find the location quickly.

Advantages of using fixed VoIP service:

  • One of the advantages of fixed VoIP numbers is that they are viewed as more authentic and reliable by consumers. Fixed VoIP numbers are associated with a physical address, which gives the impression of a stable, long-term business.
  • Fixed VoIP uses an internet connection to transmit voice data, significantly reducing the cost of calls, regardless of the distance.
  • Fixed VoIP numbers allow you to update your caller ID and republish it to a CNAM (Caller Name and Number) database. This means that a business can change the name or phone number that appears on a caller ID display for marketing or branding purposes.
  • Fixed VoIP numbers provide extra benefits in emergencies since they are associated with a physical address. 

Disadvantages of using fixed VoIP service: 

  • Compared to other VoIP systems, fixed VoIP systems require a more intensive setup. This is due to their requirement to connect to the PSTN, which means a physical address and number are necessary before you can begin using this system.
  • Fixed VoIP numbers are attached to a specific address. This means that you are limited in the areas where you can receive calls and where you can set up your business.
  • If you’re traveling or doing business overseas, you cannot use your fixed VoIP phone number.

How to trace a fixed VoIP number

The first step in tracing a fixed VoIP number is to collect all the information you have on the caller. This includes the phone number, the date, and time the call was made, and any other details like the caller’s name or company name. You can also check any voicemail messages left by the caller. This information will help you narrow down your search and give you more leads.

Once you have all the necessary information, you need to use a VoIP lookup tool to trace the caller. One such tool is the American Registry for Internet Numbers (ARIN).

Internet-Assigned-Numbers-Authority

ARIN provides an online service that allows you to search for IP addresses and domain names. Another tool is the Internet Assigned Numbers Authority (IANA), which manages IP addresses and helps identify the geographic location of the number.

What does non-fixed VoIP mean

Non-fixed VoIP (Voice over Internet Protocol) refers to a virtual phone number assigned to a user rather than a physical phone line. This means that a non-fixed VoIP number is not restricted to any physical location or address.

Unlike traditional phone numbers, which are restricted to a specific area code, non-fixed VoIP numbers can be assigned with any area code or country format. Non-fixed VoIP numbers can be created with just an email address and payment method, making it an affordable and flexible option for businesses.

Advantages of using non-fixed VoIP service:

  • One of the most significant benefits of Non-Fixed VoIP is the flexibility and scalability it offers. With Non-Fixed VoIP, businesses can connect their employees and customers from anywhere and at any time. 
  • Non-fixed VoIP numbers can be added in minutes via a VoIP app, without the need for additional hardware or wiring. 
  • Businesses can track the usage of each number with analytics and call logs. You can use call center analytics and call logs to monitor each agent’s activity and track the usage of each number. 
  • Lastly, Non-fixed VoIP technology offers companies the flexibility to buy multiple types of remote numbers. Toll-free, vanity and local numbers can be purchased, allowing companies to establish a local presence wherever they want.

Disadvantages of using non-fixed VoIP service: 

  • One of the limitations of non-fixed VoIP is the risk of fraud or spam callers. Because non-fixed VoIP allows for anonymous phone numbers, spammers can easily hide their identity and use non-fixed VoIP to commit fraud or spam. 
  • Call quality can be affected by using a non-fixed VoIP system, which relies on the Internet for voice transmission. 
  • Another drawback of using non-fixed VoIP numbers is the risk of inconsistency. Non-fixed VoIP numbers can change or vary from time to time, making it difficult to answer customer calls with the same number. 

Who uses a non-fixed VoIP number?  

Non-Fixed VoIP numbers are used by individuals and businesses seeking flexible and mobile communication solutions. Here are some categories of users who typically use Non-Fixed VoIP numbers:

Who-uses-a-Non-Fixed-VoIP-number

1/ Virtual Call Centers: Companies with virtual call centers can benefit from non-fixed VoIP numbers because they can have local phone numbers in different areas without needing a physical presence. This allows them to serve customers better and appear more legitimate.

2/ IT Professionals: IT Professionals can benefit from non-fixed VoIP because they can set up phone systems for clients without the need for extensive physical infrastructure. Non-fixed VoIP numbers can be easily associated with multiple geographical locations, making it easier to set up and manage phone systems remotely.

3/ Startups: Startups can benefit from non-fixed VoIP because it can help them save costs while maintaining a professional image. With non-fixed VoIP numbers, startups can have local numbers in various locations without needing to set up a physical presence. This allows startups to focus on their core business activities and promote a professional image even if they don’t have a physical office.

4/ Remote Workers: Remote work has become all too common in recent years, and non-fixed VoIP numbers are the perfect solution for remote workers in need of a phone line. These numbers allow remote workers to have a local presence regardless of their location, making it easier to connect with clients and coworkers.

Can a non-fixed VoIP be traced?

While it is possible to trace a non-fixed VoIP number, it is not always easy. Non-fixed VoIP numbers can be difficult to trace since they are not linked to a physical address or a carrier service like traditional phone lines. 

To locate an unfixed VoIP number, you’ll need extra details like the owner’s name and a corresponding IP address. Gathering this information provides more context and allows for better tracking of the non-fixed VoIP number.

Reverse phone lookup is one method that can be used to trace a non-fixed VoIP number. Through this method, you can obtain the owner’s name and other relevant contact details that can help you track the location of the number.

Another method of tracing a non-fixed VoIP number is by contacting the VoIP provider. This could involve sending a request to the provider for information regarding the owner or the usage of the number.

Access to this information is usually governed by a set of rules and regulations, which differ from one provider to another. It’s important to note that contacting the VoIP provider may not give the desired results as some providers may not disclose information.

12 key differences between Fixed VoIP and Non-Fixed VoIP

1/ Physical Address:

Fixed VoIP numbers are associated with a physical address, while non-fixed VoIP numbers are not. This means that if your business has a fixed address, a fixed VoIP number would be more beneficial because it allows you to show your location to your customers.

Non-fixed VoIP numbers, on the other hand, provide more flexibility to businesses because they can be used from any location, making them ideal for remote teams and businesses that are spread across multiple locations.

2/ Calling:

Fixed VoIP numbers use the Internet to make calls to any number, while non-fixed VoIP numbers can make calls remotely from any Internet-connected device. This means that fixed VoIP services can be used from any device that has a reliable internet connection.

Non-fixed VoIP services, on the other hand, are more versatile and can be used from any device, including smartphones and tablets.

3/ Setup:

Fixed VoIP numbers require a more advanced setup, usually connecting to a landline system via a SIP trunk, while non-fixed VoIP numbers can be easily set up through a VoIP app.

If you have a complex business phone system that requires integration with multiple tools, a fixed VoIP number would be the best choice for you. However, if you have a simple business phone system, a non-fixed VoIP number could save you the time and expense of installation.

4/ Reputation and Flexibility:

Fixed VoIP numbers provide stronger business reputability, while non-fixed numbers offer flexibility and scalability for remote teams. A fixed number allows customers to identify your location and enhances your reputation as a reputable company.

Alternatively, a non-fixed number can provide more flexibility to your business, making it easier for your team to work remotely, save on costs, and adapt quickly to changes.

5/ Consistent Caller ID:

Fixed VoIP numbers have a consistent caller ID, helping customers build familiarity, while non-fixed numbers may result in inconsistency if users switch numbers. If your business is looking for a consistent customer experience, a fixed VoIP number would be a better choice.

6/ Emergency Services:

Fixed VoIP numbers have dependable 911 calling as they register with a specific business address, while non-fixed numbers pose a challenge for emergency services in identifying the caller’s address. If your business requires a reliable emergency service, a fixed VoIP number is the better choice as it provides a physical address registered with 911.

7/ Caller ID:

Fixed VoIP numbers restrict the caller ID to the physical address, while non-fixed numbers allow companies to establish a local presence wherever they want. This means that with a non-fixed VoIP number, you can easily establish a local presence in any region where you desire to expand your business. 

8/ Cost:

Fixed VoIP lines are usually more expensive due to the advanced setup, while non-fixed VoIP numbers are easy to obtain and add to a VoIP app.

A fixed VoIP number requires advanced setup and integration with multiple tools, making it a more expensive option. A non-fixed VoIP number, in contrast, is less expensive and can be easily added to any VoIP app.

9/ Business Type:

Fixed VoIP numbers are commonly used by businesses and call centers, while non-fixed numbers are popular among remote teams and scaling companies.

Depending on your business type, a fixed VoIP number may be more beneficial to meet your communication needs. Non-fixed numbers are preferred by businesses that place a high value on flexibility and remote working.

10/ Maintenance and updates:

In the case of Fixed VoIP, the hardware and infrastructure are typically located on-site or at a specific physical location. This means that any maintenance activities, including software updates, configurations, and troubleshooting, often require a technician or IT personnel to physically visit the location.

Non-fixed VoIP, on the other hand, relies on cloud-based infrastructure and software solutions. This means that the core components of the VoIP system are hosted in the cloud rather than on-premises. Maintenance tasks, including software updates and configurations, can be performed remotely through the cloud.

11/ Tracking:

Non-fixed VoIP numbers are difficult to track, and attempts to track them often fail. If your business requires a reliable tracking system, a fixed VoIP number would be a better choice.

12/ Integration capabilities:

Fixed VoIP systems, often being more traditional and hardware-dependent, have limited integration with collaborative tools and applications. The infrastructure of Fixed VoIP might not be designed to easily connect with the latest software solutions and collaboration platforms. 

Whereas, Non-fixed VoIP, especially those based on cloud solutions, often has greater flexibility and compatibility with a wide range of applications and services. Cloud-based Non-fixed VoIP systems are designed to be more adaptable, allowing for seamless integration with modern collaborative tools.
