Digisource — 3CX voice and managed IT provider in Randburg
Digisource (Pty) Ltd is a Randburg IT support business with seventeen years in the industry, and voice is one line of a wider stack rather than its specialism. It runs business telephony on 3CX alongside managed IT, cloud, web services, backup and a security practice that reaches into DMARC and human risk management. If you want the phones and the laptops handled by the same team, that is the proposition.
Key facts
| Who they are | Digisource (Pty) Ltd, describing itself as a full-service IT support organisation and stating seventeen years in the industry. Voice and data sit inside a broader managed-IT offering |
| Voice | Business telephony delivered on 3CX. 3CX is a widely deployed platform, which is worth knowing for a practical reason: if you ever change supplier, plenty of other providers can support the same system, so you are less locked in than with a proprietary platform |
| Core business | IT support and managed services. If telephony is your only requirement, weigh a dedicated voice provider alongside — this is an IT house that also does phones, and the listing says so rather than implying otherwise |
| Security | A security practice covering DMARC and what the company calls human risk management, which is phishing and user-behaviour work rather than firewalls alone. That is a more current framing than most IT resellers offer |
| Also offers | Cloud services, web services, backup services and managed services |
| Head office | 19 Daniel Street, Daniel Brinkpark, Randburg, 2194, Gauteng. Published on the site and confirmed exactly on the company Google Business Profile |
| Pricing | Quote-based. No per-extension, per-seat or support-contract figures are published |
| Founded | Not publicly stated as a year. The company claims seventeen years in the industry, which is a tenure claim rather than a founding date, so no year is given here |
| Customer rating | 5.0 out of 5 from 7 Google reviews, sampled 30 Jul 2026. Above the display threshold but still a small sample, so read the reviews rather than the average |
| ICASA licence | No ICASA reference is published. Ask which licensed operator carries the voice service, since 3CX is the platform rather than the carrier |
| Listed In | Cloud PBX Providers |
3CX from the people who already fix your laptops
There is a practical logic to buying phones from your IT supplier. Voice problems are frequently network problems, and when the phone system and the network sit with different companies you can spend a fortnight watching them point at each other. One supplier removes that argument entirely. The 3CX choice reinforces it: the platform is common enough in South Africa that support is portable, so you are not trapped if the relationship ends. Set against that, an IT house is not a voice specialist. For straightforward requirements — extensions, a hunt group, voicemail to email — that gap rarely shows. For a contact centre, complex call flows or CRM integration, compare a dedicated provider before deciding. Two questions to ask. Where is the 3CX instance hosted, since that decides what happens to your phones during an internet outage. And is voice support handled in-house or subcontracted, because the answer tells you who actually picks up when the phones are the thing that has stopped. Compare the wider market in the cloud PBX directory.
Who Digisource is a fit for
- Randburg and Johannesburg businesses wanting phones and IT from one supplier
- Buyers who want a widely supported platform rather than a proprietary one
- Companies that also want email security and user-awareness work covered
