Technological innovations have brought many new developments, including VoIP numbers, the virtual phone numbers you use like regular ones. The catch is VoIP numbers facilitate calls using an Internet connection.

Although cell phones have existed for years, new possibilities like making calls via software apps and social media platforms are revolutionizing the digital space.

Unlike regular wired phones, VoIP (Voice over Internet Protocol) numbers are versatile, making communication possible on any device and across various locations with an internet connection.

This revolutionary communication medium is fast becoming the leading phone service solution for all industries and personal use. This article will help you learn about VoIP numbers and why they could take center stage in communication.

What is VoIP number

VoIP Number – What Does it Mean?

A VoIP (Voice over Internet Protocol) number uses the Internet to transmit voice calls. You can make and receive calls from anywhere with just an internet connection. 

VoIP numbers offer several benefits over traditional landlines and mobile phones. The number is unique, comprising 10 digits accessible on all compatible devices. 

Unlike landlines and network-based phones, you operate in a cloud-based technology system by signing into any VoIP service. 

Considering the nature of several businesses, VoIP Number is set to revolutionize how they communicate with customers or employees thanks to the numerous capabilities of this phone system. Communication is now possible from anywhere and even on the go.

How Does a VoIP Number Work?

The Voice Over Internet Protocol functions through Internet servers. They work through a series of broadband connections, unlike traditional phone services.

In a nutshell, VoIP Number works like Skype. The call flows through an established path; your voice is processed into digital data and passed to the recipient’s phone through the Internet. The recipient’s phone then converts the digital data into sound so they can hear you.

VoIP is not limited to calls alone. It extends its functionality to chat and text communication methods. 

In an organizational setting, VoIP phone numbers can be assigned to staff members, remote and onsite, as an effective tool for passing information. 

VoIP Phone vs. Landline

VoIP phones utilize internet connectivity and convert voice calls into data packets, offering advanced features and flexibility while relying on a stable internet connection for optimal call quality. 

They are portable, allowing users to access their phone services from any internet-connected device. Cost-wise, VoIP calls can be more cost-effective for long-distance or international calls.

On the other hand, landline phones rely on traditional analog copper wiring, providing consistent call quality and not relying on internet-related connections. 

Moreover, landlines offer basic features, have fixed monthly fees, and are tied to a specific physical location, lacking the portability of VoIP phones. 

Considering VoIP phones’ numerous benefits and capabilities, users or executives who’re always on the go can utilize their efficiency to keep the team productive from anywhere. 

How to Get a VoIP Number

The first step to securing a VoIP number is subscribing to a service provider’s plan. Due to the demand for VoIP numbers, several service providers have emerged, offering competitive intents to cater to the needs of the growing market. 

However, a comprehensive assessment should be in place when selecting a vendor for your VoIP numbers.

It’s worth noting that a scale applies to the kind of service you select. The right service provider will ensure the best features are selected for you at the most minimal cost. Also, avoid adding more benefits than needed to reduce price increments. 

One good thing about every service plan offered or subscribed to is that they always have end dates. So, users can choose another provider after the last expiration, especially if the services aren’t up to par.  

Here are some factors to consider when choosing a good VoIP provider:

  • Features: Ensure the VoIP provider you choose offers the features you need, such as call forwarding, voicemail, and call recording, based on your device capacity and speed.
  • Pricing: VoIP providers offer a variety of pricing plans, so be sure to compare prices before you choose a provider.
  • Customer Support: Your chosen service provider should possess sound customer support systems for effective management. 

After registration, new phone numbers are issued for use, or if you already have an existing one, you can use it too. 

All information on the existing phone service will be transferred to the VoIP registered number through number porting, a system legally approved by the Federal Communications Commission.

The final step is to choose a subscription type, confirm the number on your preferred devices, and use it immediately. 

Benefits of Using a VoIP Number

There are notable benefits that landlines and regular phone numbers can’t provide that are available with a VoIP Number. 

A majority of them include:

Cost Effectiveness

VoIP has much cheaper call rates than traditional landline or mobile phone calls. The services could offer this benefit because VoIP providers do not have to pay for the same infrastructure as conventional phone companies. 

The Internet is utilized in this case with a monthly subscription fee less than the price of maintaining a phone line. 

There are added features too on whatever fee you pay. The primary inclusions include one-click conference calls, call recordings, automatic responses, and call waiting. 

As a bonus package, a toll-free VoIP Number can come without charge. 


VoIP numbers can be used on various devices, including smartphones, tablets, and computers. This means you can take your phone number wherever you go. It makes all forms of communication easy to access based on reliable connections. 

Also, VoIP consumes fewer data, and you can place calls effectively with solid Wi-Fi signals. Hence, communication across long distances is possible within the same country or even halfway across the globe.


No specific location is tied to a VoIP number to enable you to use them anywhere. This is ideal for businesses with remote employees or individuals who travel frequently. 

They also work best with multiple devices, as there are several ways to blend them into your work accessories. 

For example, your traditional telephone can use a VoIP number through an Analog Telephone Adapter (ATA). The adapter functions like a bridge to the digital system and establishes connections to various bandwidths. 

Improved Voice Quality

VoIP harnesses cutting-edge audio compression technology, called “codecs,” to transform sound into digital format, eradicating distortions and background noise. 

While transmitting it through the Internet, VoIP achieves enhanced call clarity using the G.722 codec, as it possesses twice the bandwidth capacity of a traditional analog phone call. This innovative approach ensures high-definition (HD) call quality for VoIP users. 

Area Code Preference

VoIP phone numbers offer the freedom to choose area codes beyond one’s city or state, allowing for cost-free long-distance calls. 

This flexibility also enables business owners to establish credibility by assigning themselves local numbers, which proves advantageous for multi-location businesses.

Conventional phones do not share this luxury, making it one of the reasons people queue in line to get a VoIP number. 

Types of VoIP Numbers

VoIP types

Selecting a number type can be one of the benefits of VoIP. There are three main types, and each serves different purposes. 

Local Numbers

Local numbers are assigned to a specific geographic area. When someone calls your local number, it will appear as if they are calling you from within that area. 

This is beneficial for business owners seeking patronage. Many buyers like purchasing goods from companies around them with a local customer care line. 

So, choosing a local VoIP number helps secure your customer base. 

Toll-free Numbers

Toll-free numbers are free to call from anywhere in the particular region. This makes them ideal for businesses that want to provide a customer service number that is easy to remember and use at no charge. 

Your customers can reach you and request services as much as they want in a day. 

Vanity Numbers

Effective branding is necessary for business success, and your phone number can contribute to this strategy. 

Having a unique number related to your business can leave a lasting impression on people’s minds and motivate them to reach out.

For instance, obtaining a vanity number such as 1-800-JEW-ELS would be a wise choice if you own a jewelry store. 

With VoIP, you can select your vanity number, personalize your contact details according to your business, and enhance brand recognition. 

VoIP Fraud

The convenience and cost-effectiveness of Voice over Internet Protocol (VoIP) technology has made it an excellent choice for organizational and personal use.

However, along with its numerous benefits, VoIP also brings new challenges in the form of fraud and phishing attacks.

These malicious activities exploit vulnerabilities in VoIP systems, posing significant risks to both personal and organizational communication. 

Understanding the nature of VoIP fraud and phishing is essential to safeguard your communication and protect sensitive information. 

VoIP fraud refers to unauthorized access and misuse of VoIP systems for fraudulent purposes. It involves the exploitation of security weaknesses, resulting in financial losses, unauthorized calls, identity theft, and compromised data. 

Attackers employ various techniques to carry out VoIP fraud, including: 

  • Call Hacking: Hackers gain unauthorized access to VoIP systems, allowing them to make calls at the expense of the system owner. These fraudulent calls can occur locally or internationally, resulting in substantial financial burdens.
  • Toll Fraud: Attackers exploit vulnerabilities in VoIP systems to manipulate call routing and bypass toll charges. They reroute calls through unauthorized paths, circumventing call termination fees and causing significant financial losses for service providers.
  • Phreaking: Phreaking involves manipulating telecommunication systems, including VoIP, to make free calls, gain unauthorized access to networks, or tamper with billing systems.
  • Subscription Fraud: Attackers use stolen or fake identities to sign up for VoIP services, using them for malicious purposes without detection. This can include conducting illegal activities or making fraudulent calls.

VoIP Phishing

Phishing attacks in the context of VoIP specifically target the users of VoIP services, aiming to deceive them into revealing sensitive information or performing actions that compromise their security. 

These attacks often involve social engineering techniques and impersonation to trick users into providing personal data, login credentials, or financial information. 

Some common forms of VoIP phishing attacks include: 

  • Vishing (Voice Phishing): Attackers use automated voice messages or live calls to deceive users into disclosing sensitive information. They may impersonate trusted entities, such as banks or service providers, to gain the victims’ trust.
  • Caller ID Spoofing: Attackers manipulate the caller ID information displayed to recipients, making it appear that the call originates from a legitimate source. This deceptive tactic aims to trick users into answering calls and disclosing confidential information.
  • Malicious Call Redirect: Hackers gain control of VoIP systems or compromise user accounts to redirect incoming calls to unauthorized destinations. 
  • Smishing (SMS Phishing): Phishing attempts through SMS messages can target VoIP users, tricking them into clicking on malicious links or disclosing sensitive information via text responses.

How to Protect Against VoIP Fraud

The consequences of VoIP fraud and phishing can be severe, including financial losses, compromised privacy, and damage to reputation. 

To mitigate these risks, individuals and organizations can take several proactive measures: 

  • Strong Security Practices: Implement authentication mechanisms, secure passwords, and constant changes to protect VoIP systems from unauthorized access.
  • Regular Software Updates: Keep VoIP software and hardware updated with security firewalls to block easy access.
  • User Awareness and Training: Educate yourself about the risks associated with VoIP fraud and phishing. Emphasis should be on avoiding suspicious calls and messages and reporting potential scams.
  • Monitoring and Analytics: Employ monitoring tools to identify abnormal call patterns, detect unusual activities, and respond promptly to potential fraud or phishing threats.


VoIP numbers have become essential for contemporary businesses, replacing traditional landline telephones with internet-based calling capabilities. 

Unlike the limitations of fixed telephone lines, VoIP services enable enterprises to connect their devices and make calls from any location with just internet access. 

Even so, take great care when selecting the correct phone number service, management, and security of your VoIP numbers.

While it can be tricky to choose from the various VoIP phone number providers, focus on features, customer support, pricing, security, etc., to make the right choice.
