Advanced Voice Systems — VoIP and business phone system provider in Gauteng
Advanced Voice Systems has sold business telephony in Gauteng since 2004 and publishes something most of its competitors will not: a starting price. Cloud-hosted extensions begin at R65 each. The range runs from cloud and on-premise PBX to virtual receptionist and work-from-home setups, on Mitel, NEC and Yealink equipment, and the company also handles the unglamorous end of the business — moving a system, supporting a legacy one, or decommissioning it.
Key facts
| Who they are | A Gauteng business telephony provider established in 2004, selling cloud-hosted and on-premise phone systems with the connectivity to run them, and reaching the rest of South Africa and Sub-Saharan Africa through a dealer network |
| Voice | Cloud-hosted phone systems, on-premise PBX, virtual receptionist and work-from-home setups. Base cloud packages start at R65 per extension, which is a published figure and a rare one in this category |
| Platforms | Mitel and NEC systems with Yealink handsets. Mitel and NEC are both enterprise-grade lines, so this is a supplier comfortable with larger on-premise estates rather than only small cloud deployments |
| Connectivity | VoIP and SIP trunking, plus fibre, LTE and wireless access, so the line and the phone system can come from one supplier |
| Lifecycle services | The company supports legacy systems, relocates installations and handles de-installation and recycling. That matters if you have an ageing PBX you are not ready to replace, or an office move where the phones have to survive the trip |
| Offices | The site publishes 47 Umgeni Road, Farramere, Benoni, 1501. The company Google Business Profile, on the same domain and the same phone number, gives 132 7th Avenue, Edenvale, 1609. Both are Gauteng; confirm which one takes visitors |
| Also offers | CCTV and Wi-Fi solutions, and finance arrangements for qualifying clients |
| Customer rating | No rating is shown. The company’s Google Business Profile carries no reviews, and WhichVoIP publishes Google ratings only, above a five-review threshold |
| ICASA licence | No ICASA reference is published. Ask for it in writing if your procurement process records licence numbers |

A published starting price and a way out
Two details make this supplier easier to assess than most. The first is that R65 per extension is written down, so you can sanity-check a quote before the conversation starts rather than after. The second is less obvious but arguably more useful: the company will support a legacy system, move an installation and decommission old equipment. Most cloud-first providers want you to replace everything on day one, which is fine if your PBX is already dead and expensive if it is not. Being able to keep an NEC or Mitel estate running while you plan the migration, then have the same supplier move or strip it out, is a genuine advantage for a business that cannot rip and replace in one weekend. The vendor list points the same way: Mitel and NEC are enterprise lines, so this is not purely a small-office cloud shop. Set against that, there is no published customer rating and no ICASA reference, and the two addresses on the two sources need clarifying. Twenty years of trading and a dealer network reaching beyond Gauteng are the reassurance. Compare the wider market in the VoIP provider directory.
Who Advanced Voice Systems is a fit for
- Gauteng businesses with an existing Mitel or NEC system to keep, migrate or move
