With VoIP, your internet line is the real coverage question
Stellar delivers voice over your existing internet connection rather than a fixed geographic network, so it reaches any South African site with a stable line. It works across cloud phone-system platforms — 3CX, Vodia and VPBX — and the right fit depends on your feature and licensing needs. That moves the coverage question off geography and onto the quality and resilience of the fibre or wireless connection at each of your offices.
Who Stellar Technologies is a fit for
- Businesses wanting to cut call costs by moving off legacy copper lines to a managed VoIP phone system.
- Teams that want a choice of platform — 3CX, Vodia or VPBX — mapped to how they actually work.
- Multi-branch or remote operations that need extensions to move with the user rather than the desk.

What does Stellar Technologies do?
Stellar Technologies is a Centurion-based ICT and VoIP provider. It sets businesses up with modern cloud phone systems on platforms such as 3CX, Vodia and VPBX, handles VoIP calling to cut call costs, and provides supporting network and ICT services. The aim is a single managed voice setup for office, remote and international calling.
Which phone systems does Stellar Technologies support?
Stellar works across several IP phone-system platforms, including 3CX, Vodia and VPBX. These are modern software-based systems that replace a traditional on-site PBX, run over your internet connection, and add features like call queues, voicemail-to-email and remote extensions.
Can Stellar Technologies replace our old telephone lines?
Yes. Moving from legacy copper lines to a VoIP phone system is the core of what Stellar does. In most cases you can keep your existing numbers by porting them across, then make and receive calls over your internet line, which is where the call-cost savings come from.
What internet speed and quality does VoIP need?
Roughly 100 kbps per simultaneous call, so the total depends on how many people are on calls at once. Low latency and low jitter matter more than headline download speed, which is why a stable fibre or wireless line at each site is the real requirement.
Does it keep working during load-shedding?
The hosted phone-system platform stays online in the cloud. Calls continue for as long as the router and internet line at each site have battery or UPS backup, so power resilience at your premises is what to plan for.
Where is Stellar Technologies based?
Stellar Technologies operates from Centurion in Gauteng, with its office at Oxford Office Park in Highveld. It serves businesses across South Africa, since the VoIP and cloud phone-system platforms it sets up are delivered over the internet rather than tied to a single location.
