What Is a VoIP Phone Number?

A VoIP phone number is a business telephone number that operates over the internet rather than traditional copper landlines. Instead of being tied to a physical phone line, VoIP numbers are hosted in the cloud.

This means your business can make and receive calls from multiple devices including desktop phones, laptops, and mobile apps. Whether your team works from the office, remotely, or across multiple locations, VoIP phone numbers keep everyone connected using the same business number.

How VoIP Phone Numbers Work

VoIP phone numbers work by routing calls through your internet connection rather than traditional telephone infrastructure. When someone calls your number, the VoIP system converts the voice signal into digital data and sends it through the internet to your phone system.

With a cloud PBX, incoming calls can ring multiple devices at once. Your business number can connect to desk phones, laptops, softphones, or mobile apps, allowing teams to answer calls from anywhere.

Port Your Number with Zero Hassle

Number porting allows businesses to transfer their existing landline or VoIP number from their current provider to a new VoIP system without changing the number customers already know. This ensures continuity for your business while upgrading to a more flexible communication platform.

We know how critical your phone number is. That’s why we’ve made switching from your old provider to Voys seamless and stress-free. Our team manages the technical steps, so you don’t have to lift a finger.

Whether you’re upgrading your business phone system or switching VoIP providers, porting your number to Voys takes just a few days, with zero impact on your operations.

Prefer a New Number? You’ve Got Options

Businesses often choose new VoIP numbers when expanding into new cities, creating separate support lines, or establishing a nationwide presence.

Need a new number that fits your brand or coverage needs? Choose from:

  • Local geographic numbers like 021 (Cape Town) or 012 (Pretoria) to build trust in key markets.
  • Non-geographic 087 numbers for nationwide reach.

With Voys, you can expand your reach and shape your business identity—locally and globally.

What is a geographic phone number?

A geographic phone number is a fixed land line telephone number beginning with a geographically assigned area code (e.g. 012 for Pretoria, 021 for Cape Town). The primary advantage of geographic phone numbers is that they are widely recognised and trusted by local customers. When you acquire a 012 0r 021 number through Voys, you automatically get access to our self-service web portal. This means you have access to a fully-fledged business phone system with all the bells and whistles. We put the power in your hands. Easily self-manage your phone system from anywhere, any time. That’s Freedom!

What is a non-geographic phone number?

Unlike traditional fixed-line numbers, non-geographic telephone numbers (087 numbers) are regarded as ‘national’ numbers . Non-geographic numbers can not be traced back to a certain city or region within South Africa. Such numbers are commonly used by organisations that conduct business nationwide, not just in a specific area. Traditionally, 087 numbers are used to serve clients from one central call center. Calls can then be transferred to departments that are located anywhere in the country. 087 numbers are best suited for businesses who wish to establish the perception of having a national presence.
