What is a VoIP Number?

VoIP numbers use cloud-based VoIP technology that lets you receive and make calls with the same number using an app on your desk phone, mobile device, or computer.

A VoIP phone number facilitates calls using the Internet and doesn’t depend on geographic location or a particular device. As such, you can make calls to multiple locations and devices since they don’t require a physical connection to a Public Switched Telephone Network (PSTN).

Instead, the service assigns a number to a user, department, or entire business. As it’s cloud-based, this means you can place and take calls on any device with a WiFi or broadband connection — including from your smartphone, computer, tablet, or VoIP-enabled landline.

Techopedia Explains VoIP Numbers

A VoIP number converts traditional analog phone audio into small digital data packets, which are then transmitted through the internet to the destination. It’s then reassembled into high-quality audio to ensure uninterrupted communication.

On the other hand, traditional phone systems use circuit switching. When you make a call, it’s routed through the switch operated by the local carrier. Once the person picks up the phone, a circuit is opened, and the connection remains active until either party disconnects.

To sum up, unlike traditional phone systems that rely on circuit switching, VoIP services use packet switching, which sends and receives data only as needed rather than using physical lines. They also provide flexibility by offering different types of VoIP numbers.

Types of VoIP Phone Numbers

Local NumbersToll-Free NumbersVanity Numbers

These numbers start with an area code specific to a city, region, or state. These are ideal for businesses that operate locally and have a localized customer base, as they allow them to create a strong local presence, reduce long-distance calling costs, and make it easy for customers to remember the business’ number.

VoIP internet phone services offer toll-free numbers that allow customers to reach businesses without incurring charges. These numbers often start with prefixes like 800, 888, 887, and 886, and they help enhance business credibility.

Vanity numbers are a combination of alphanumeric phrasing and toll-free number prefixes. It spells out an acronym using letters, words, or names on the telephone keypad and makes it easier for customers to dial and remember your number.

For example, if your business name is Boris’ Pet Supplies, choose a number like 1-800-BORIS-PET. With VoIP, you can choose your own vanity number and make your brand more memorable.
