Meet OmniOne by Vox: A Cloud PBX built for mobility, control and resilience, on a Locally Owned Network
South African businesses have long battled the same frustrations: ageing on-premises PBX hardware, fragmented communication tools, multiple vendors with multiple SLAs — and a phone system that goes dark the moment load shedding kicks in.
Vox is changing that. The SA-owned telecoms provider has officially launched Vox OmniOne PBX, a fully Cloud-based, business communications platform built and run entirely on Vox’s own South African network. It’s a significant moment for local businesses looking to modernise how they communicate — without outsourcing their voice infrastructure to an overseas cloud provider.
Let’s Start with the: What Is Vox OmniOne PBX?
OmniOne is Vox’s own Cloud communications platform — designed for how people really work today – mobile, flexible and always connected. It runs on Vox’s geo-redundant, carrier-grade SA voice network, meaning the infrastructure is locally owned, locally managed, and built specifically for the realities of doing business in South Africa.
Unlike traditional PBX setups that rely on physical hardware at your premises, OmniOne is 100% Cloud-based. There’s no capital expenditure on equipment, no on-site maintenance, and no single point of failure sitting in your server room.
The platform is powered by PortaOne and managed end-to-end by Vox — giving businesses one owner, one SLA, and one support team responsible for everything from fibre connectivity to call termination.
Why It Matters: The Problem OmniOne Solves:
If you’ve run a business phone system in South Africa, the pain points are familiar. From day one, OmniOne focuses on 4 things that businesses care most about:
- Mobility: Remote staff relying on personal phones to stay connected.
- Control: Simple changes requiring support calls, delays, and unnecessary admin.
- Resilience: When the power goes out, so does your PBX.
- Quality: When something goes wrong or quality is poor, multiple vendors and SLAs mean no one takes ownership
OmniOne addresses every one of these with a single, integrated solution.
Key Features of Vox OmniOne PBX

OmniOne runs on geo-redundant, carrier-grade infrastructure built and managed entirely by Vox. No third-party dependency, no overseas cloud providers — just a South African network built for South African conditions.
2. Loadshedding Resilience:
When the power goes out at your office, OmniOne stays live in Vox’s data centres. Calls automatically fall back to the mobile app on the same extension — so your business number keeps ringing, no matter what Eskom is doing.
