A landline number without the landline
The virtual landline is the sharp end of what Codex Tech sells. A business gets a geographic number that customers recognise, and the calls land on an app or a desk phone wherever the team happens to be. For a small company that has outgrown a mobile number but does not want a copper line or a full PBX, that is a genuinely useful product, and the published quarterly pricing makes it easy to size. Scaling up moves you into multi-user cloud PBX, where the internet line becomes the thing that decides call quality. Codex Tech sells fibre too, so both sides can come from one supplier. Take the missing street address into account when you weigh it up: for a service business that matters less than it would for hardware, but ask where the support team actually sits. Other platforms are in the cloud PBX directory.
Who Codex Tech is a fit for
- Small businesses wanting a landline number without a fixed line
- Distributed teams taking business calls on personal handsets through an app
- Companies wanting telephony, a website and connectivity from one supplier

What is a virtual landline?
A geographic phone number that is not tied to a physical line. Calls route to an app, a softphone or a desk handset wherever your team is, so a business can present a local number without renting a copper line.
How much does Codex Tech charge?
A single-user virtual landline is advertised at R747 per three months and a three-user business landline or cloud PBX at R2,241 per three months. Marketing also quotes R249 per user per month, so ask which basis your quote uses.
Can I keep my existing number?
Number porting is standard practice for South African hosted voice. Ask for the timeline in writing and what happens to inbound calls during the cutover, since that window is where most porting pain lands.
Where is Codex Tech based?
The company lists contact points in Durban and Cape Town but does not publish a street address on its site. If a physical office matters to you, ask for it directly.
Do they offer toll-free numbers?
Yes. Toll-free and 086 numbers are part of the offering, which suits a business running inbound sales or support lines. Ask how per-minute charges work on inbound toll-free traffic, since the called party carries the cost.
What internet do I need for cloud PBX?
Around 100kbps of stable upload per concurrent call. Stability matters more than headline speed. Codex Tech also sells fibre, so the line and the phone system can be sized by the same supplier.
