What is a VoIP Number? 

A VoIP number is a virtual phone number that works with VoIP (Voice Over Internet Protocol). VoIP does not require a specific internet bandwidth, but a fast internet speed is recommended for a smoother experience. There are even mobile phones with LTE, 4G, and 5G networks that can transmit voice-over data networks.  Additionally, VoIP supports virtual numbers, which are not tied to a specific phone line or device, offering flexibility and enabling call routing to any chosen phone number.

How does VoIP work?

VoIP technology allows you to make voice calls using a high-speed internet connection instead of a regular phone line. However, you can make outbound calls, send messages, and receive incoming calls only with an internet connection.VoIP converts your voice into digital data packets transmitted to the receiver.

In other words, participants in a VoIP call will be unable to distinguish between traditional and VoIP calls due to their instantaneous nature.

Types of VoIP Numbers

Geographic VoIP Numbers:

• Local VoIP Numbers: These numbers have area codes specific to a particular geographic region, making them appear as local numbers to residents in that area. They are ideal for businesses wanting a local presence in different regions without a physical office.
• International VoIP Numbers: These numbers have area codes for countries outside the user's home country, enabling businesses to establish a local presence in foreign markets. They are beneficial for companies with international clients or operations.

Toll-Free VoIP Numbers

These numbers typically start with prefixes like 800, 888, 877, 866, 855, 844, or 833, allowing callers to reach the business without incurring charges. They are helpful for customer service lines and companies aiming to offer a free calling option for their customers.

Vanity VoIP Numbers

Customised numbers that spell out a word or name related to the business, such as 1-800-FLOWERS. They enhance brand recognition and make the number easier to remember.

4. Flexible VoIP Numbers:

• Mobile VoIP Numbers: 

A mobile phone allows users to make and receive calls over the Internet. Unlike traditional mobile numbers, calls are made and received through a broadband internet connection rather than a cellular network. 

• Virtual VoIP Numbers: 

In this type, temporary usage is covered by disposable VoIP numbers and direct communication within the business by direct Inward Dialling, known as ‘DID’.These numbers can forward calls to multiple devices.

VoIP number vs Landline

VoIP is easier to set up and configure as everything is handled remotely. It uses the Internet to transmit voice data, which is significantly cheap. It has a rich feature set, including voicemail-to-email, call forwarding, video conferencing, and Integrations with other software like CRM and email. Through VoIP, we can use the Internet anywhere. However, you depend on the Internet for calls, and Internet speed could affect call quality.

A landline requires complete setup and wiring installation, which is time-consuming and more costly. It uses the PSTN with copper wires. It has basic features like caller ID, call waiting, voicemail, and other advanced features, which may cost some money. The landline is explicitly located. It provides consistent and excellent-quality calls without hassle. Adding more lines requires some cost, so it is efficient for businesses.

Why do people use a VoIP number?

People use VoIP(Voice over Internet Protocol) for the following benefits that it holds:

• Cost saving: VoIP often offers lower charges for calls and other purposes. In fact, it provides more efficient and pocket-friendly special offers for international communication and long distance.
• Flexible: You can use multiple devices and advanced features like voicemail, email, call forwarding, and video calls. 
• Scalable & portable: VoIP is scalable for businesses, allowing easy addition or removal of lines, and its portability makes it ideal for those who relocate frequently.
• Service integration: VoIP integrates well with other internet services, enhancing productivity and collaboration.
• Area codes: Compared to a local dialling code, a traditional phone number lacks that trust factor. VoIP phone numbers allow you to choose your dialling code, allowing you to display a local number to clients.

Is a VoIP number a scammer?

No, they are not inherently scammers. Scammers may use VoIP numbers because they are cheaper, easier to obtain, and can be accessed anywhere with internet access, as with other technologies. These are simply phone numbers that operate on the Internet. VoIP systems' vulnerabilities can be exposed through malware infections, network intrusions, DDoS attacks, and even phishing attempts.

Protection against VoIP fraud attacks

To protect against VoIP fraud attacks, use strong authentication with complex passwords and two-factor authentication, and secure your network with firewalls and VPNs. Implement role-based access control, deactivate unused accounts, set call restrictions, and educate employees on security best practices. Encrypt VoIP traffic using secure protocols like SRTP and TLS, keep software and firmware updated and monitor call logs for unusual activity. 

What is a non-VoIP number?

A non-VoIP number is a phone number directly connected to a SIM card. It has an area code that helps identify it quickly. A non-VoIP number is linked to a geographical area, like your phone. It perfectly protects online services and platforms.

Do both the caller and recipient need a VoIP connection?

Not a must. Only the caller needs a VoIP connection to make a call, as the VoIP system can make calls to any landline, mobile phone, or IP phone, regardless of whether the recipient has a VoIP connection. Like any other regular call, all devices, such as landlines, desk phones, SIP phones, or mobile devices, can receive VoIP calls.
