Quest Communications — business fibre, voice and managed IT provider in Johannesburg
Quest Communications works from Bradenham Hall in Rivonia and sells connectivity, cloud, voice and IT support as one outsourced service. The company states more than 25 years in the market, over 500 clients and round-the-clock support, and its voice line covers on-site and cloud-based PBX with least-cost routing. Connectivity spans fibre, wireless, remote VPN and failover for sites that cannot afford to drop.
Key facts
| Who they are | A Johannesburg IT and connectivity company selling outsourced helpdesk and support alongside internet connectivity, cloud services, network infrastructure, backups, voice and cyber security |
| Stated track record | The company publishes four figures on its own site: more than 25 years in business, over 500 clients, 24/7 support availability and 100% quality assurance. The first three are checkable claims worth putting to a reference customer |
| Voice services | On-site or cloud-based business-grade voice and PBX, with least-cost routing, scalability and mobility named as features. Least-cost routing is the line that matters commercially, so ask how it is applied and to which destinations |
| Connectivity | Fibre, wireless, remote VPN and failover solutions aimed at eliminating downtime. For a business putting its phones in the cloud, the failover product is the more important half of the conversation |
| Also offers | Microsoft 365 and Google Workspace, anti-virus and security, off-site and online backups with daily reports, network design and installation, firewalls and VPNs, and maintenance under SLA |
| Head office | Bradenham Hall, 7 Mellis Road, Rivonia, Sandton, 2128, Gauteng |
| Coverage | Johannesburg and Gauteng for on-site work, with cloud voice, remote support and backup available wherever the connection holds |
| Customer rating | No rating is shown. The company’s Google Business Profile matches its domain and address exactly, but carries two reviews, below the five-review threshold WhichVoIP requires before publishing a Google rating |
| Pricing | Not published. Formal proposals are built per client, so ask for voice, connectivity and support as separate line items if you want to compare any of them properly |
| Founded | Not stated as a year. The 25-plus-year claim implies the late 1990s or around 2000, but no founding date is published, so nothing is calculated from it here |
| ICASA licence | No reference is published. Confirm the licensed entity carrying your voice service when you request a quote |

One supplier for the line, the phones and the helpdesk
Connectivity coverage comes down to the address, and for a managed provider the more useful question is what happens when the line at that address fails. Quest sells failover as a named product alongside fibre and wireless, which is the right shape for a business also buying cloud voice from it, because a cloud PBX on a single unprotected circuit is a phone system with a single point of failure. Price the failover in the first conversation rather than the second. The consolidation argument is the real one here. When the phones, the internet, the backups and the desktop support all sit with one supplier under one SLA, a fault becomes one call rather than a negotiation between three vendors, and for a business without internal IT that is worth real money. The cost of that convenience is a bundled proposal that is hard to benchmark, so ask for each component itemised even if you intend to buy the bundle. On voice, least-cost routing is the feature with commercial consequences, so ask exactly how it works, which destinations it covers, and whether the saving is visible on the invoice. The 25-year and 500-client claims are the company’s own and easy to test through a reference customer in your sector. Compare providers and networks in the fibre directory.
Who Quest Communications is a fit for
- Johannesburg businesses without internal IT that want one supplier under one SLA
- Sites where connectivity failover matters because the phones are moving to the cloud
- Buyers who want a long-established provider and can check the 25-year claim by reference

Ask for the voice, the connectivity and the IT support quoted as separate line items even if you plan to buy them together, because a bundled proposal is very hard to benchmark.
