DcData — VoIP and cloud PBX provider in Pietermaritzburg
DcData trades as the customer-facing brand of Linux Tech (Pty) Ltd, an open-source technology house based in Pietermaritzburg. It has been selling VoIP since 2004 and pairs cloud PBX, SIP trunks and on-site IP PBX with Linux hosting, firewalls, licensing and connectivity, which is an unusual combination for a KwaZulu-Natal business of its size.
Key facts
| Who they are | DcData is the trading brand of Linux Tech (Pty) Ltd, a Pietermaritzburg technology company built around open-source infrastructure. Its own description leads with open-source technologies backed by a technical team, and the product range runs well beyond telephony |
| Voice services | Cloud PBX, SIP trunks, wholesale voice, and on-site IP PBX systems. The company states it has been providing VoIP services since 2004, though it publishes no company founding year |
| Also offers | Security including firewalls, endpoint protection and SSL certificates; cloud hosting covering mailboxes, email security, NextCloud, web and VM hosting, DNS and bulk SMS; hardware including servers, storage and phones; software licensing for Red Hat, SUSE, Microsoft and Proxmox; plus consulting and IT security auditing |
| Connectivity | Fibre, microwave, satellite and broadband wireless, quoted as available wherever you are in South Africa |
| Pricing | Quote-based. No rate card is published for voice or infrastructure |
| Head office | Block E, Hilltops Office Park, 73 Villiers Drive, Pietermaritzburg, 3201, KwaZulu-Natal |
| Coverage | National, with the operating base and technical team in KwaZulu-Natal rather than Gauteng or the Western Cape |
| ICASA licence | No ICASA reference is published. Given the company sells wholesale voice as well as retail services, it is worth asking what its licensing position is and whose number ranges your extensions would sit on |
| Customer rating | 5.0 from 20 Google reviews. The profile is titled “Linux Tech (Pty) Ltd / DcData”, carrying both the legal entity named on the website and the trading name, so the rating is unambiguously this business. Reviews run back more than a decade and several are from long-standing customers |
| Founded | Not publicly stated. The company says it has provided VoIP since 2004 but never gives a founding year, and that tenure claim is reported here as published rather than converted into a date |

An open-source shop that happens to sell phones
Most providers in this directory sell voice and add IT around the edges. DcData works the other way round. The centre of gravity is open-source infrastructure, with Red Hat, SUSE and Proxmox licensing, Linux hosting, NextCloud and firewalls, and the cloud PBX sits inside that stack rather than beside it. If your business already runs on Linux or you are trying to get out from under per-seat Microsoft licensing, having the phone system come from the same team is worth something concrete. The base in Pietermaritzburg cuts both ways and you should test it honestly. A KwaZulu-Natal business gets a supplier who can physically arrive, which most national providers cannot offer outside Gauteng and Cape Town. A Johannesburg buyer gets remote support from a small team, so ask what on-site attendance actually looks like in your city and what the response time is after hours. The twenty Google reviews are unusually long-lived, with several from customers describing more than a decade of service, and that pattern says more about a technical supplier than the score alone. Compare the wider market in the VoIP directory.
Who DcData is a fit for
- KwaZulu-Natal businesses wanting a local supplier who can attend site
- Companies running Linux or open-source infrastructure that want voice on the same stack
- Buyers who need hosting, security, licensing and telephony from one technical team

Get up to 3 quotes
Ask what on-site support looks like in your city, because the technical team is based in Pietermaritzburg and that is a real advantage in KwaZulu-Natal and a question worth pressing anywhere else. If you are considering the wider stack, ask them to quote hosting, licensing and voice together, since that is where a supplier like this tends to be strongest.
