Voice solutions, infrastructure installs, firewalls and maintenance

Keep your business talking, connected and protected. Realtime Technologies designs, installs and supports hosted PBX, structured cabling, Wi-Fi and enterprise firewalls across Gauteng.

What we deliver on every site

From the first handset to the last patch lead, we build networks that stay reliable after handover.

Voice & PABX

RTT CloudPBX and Yeastar hosted or on-site PABX. Desk phones, reception consoles and call recording.

Infrastructure

Cat5e / Cat6, Cat3 telephone, fibre and camera cabling. Cabinets, patch panels and labelled, testable runs.

Firewalls

Juniper, MikroTik, Fortinet and Zyxel USG deployments with VPN, content filtering and remote access.

Maintenance

Ongoing support, firmware updates, backup checks and on-site call-outs so systems stay in production.

Voice solutions

PABX, hosted voice and switchboards that staff actually use

A good phone system should follow your team between desk, mobile and home. We size extensions, hunt groups, IVR menus and recording so Johannesburg businesses stay reachable without extra complexity.

RTT CloudPBX — our hosted platform for multi-site and hybrid teams
Yeastar — on-premise or hybrid PABX for tighter local control
Handsets: Yealink, Fanvil, Polycom and Cisco
Call recording: Callcabinet (PCI), Voicelogger SA and ECost
Voice reseller programme available on request

Infrastructure installs

Cabling and wireless built to last the next upgrade

Most network problems start in the ceiling, not the switch. We install clean, documented infrastructure so voice, CCTV, Wi-Fi and solar monitoring can share one backbone.

Cat5e / Cat6 data and Cat3 telephone cabling
Fibre backbone and building-to-building links
RG59 and network camera cabling for CCTV
Wi-Fi: Ubiquiti, TP-Link Omada, Ruijie and Cudy
Switching: Juniper, MikroTik, Zyxel, Cisco and Ubiquiti

Firewall deployments & maintenance

Secure the edge. Then keep it current.

We deploy and maintain firewalls that match the size of your office — from a single FortiGate at reception to multi-WAN MikroTik or Juniper at a warehouse. After go-live we handle rules, VPNs, licences and firmware so the box does not become a forgotten risk.

Fortinet FortiGate — application control, SD-WAN and SSL inspection
MikroTik — cost-effective routing, VPN and QoS for growing sites
Juniper — enterprise routing and security
Zyxel USG — UTM for small and mid-size offices
Maintenance contracts: health checks, change control and on-site support

How an install typically runs

Clear scope. Neat work. Documented handover.

1. Site survey

We walk the floor, count users, check existing cabinets and confirm power, WAN and camera points.

2. Design & quote

You get a brand-specific bill of materials, cable schedule and a fixed or staged price.

3. Install & maintain

We terminate, test, label, train your team and stay on as the maintenance partner.
