Screamer Telecoms — Cloud PBX & voice provider in South Africa
Screamer Telecoms is an independent South African ISP and business-voice operator based in Olievenhoutbosch, Centurion, with more than twenty years in the market. It runs hosted PBX, a standalone VoIP line and Microsoft Teams calling over its own QoS-managed WAN rather than reselling, from R199 per user, and bundles a complimentary backup microwave link with business fibre. Because voice rides its own backbone, call routing stays under Screamer’s control rather than sitting as a best-effort overlay on a third-party line.

Screamer runs the network its hosted PBX rides on
Screamer delivers hosted PBX and Microsoft Teams calling over the internet, but the voice runs on its own QoS-managed WAN rather than a reseller’s congested pipe. That matters for a cloud PBX: call quality tracks the line each site sits on, and Screamer controls the routing behind it. Where it stands apart at its price band is the bundle — business fibre ships with a complimentary backup microwave link under a published uptime guarantee, so a primary-line failure need not take voice down with it. Pricing is mid-market rather than lowest-cost (Starter R199/user, Business R299/user), so the buying question is whether one Gauteng operator handling voice, connectivity and resilience together fits you better than stitching together the cheapest per-seat rate from separate suppliers.
Who Screamer Telecoms is a fit for
- Gauteng businesses that want voice and internet from one independent operator running its own backbone.
- Buyers for whom call quality on the carrier’s own WAN matters more than the cheapest per-seat rate.
- Teams on Microsoft 365 that want Teams calling and a bundled backup link from the same supplier as the connectivity.

Does Screamer run its own network?
Yes. Screamer states it operates its own in-house QoS-managed WAN rather than reselling a congested third party, so voice quality rides its own backbone and it controls the call routing behind your line.
What is the backup microwave link?
Screamer publishes an uptime guarantee that pairs high-speed business fibre with a complimentary backup microwave link at no additional monthly charge. If the primary fibre line drops, the microwave link is intended to keep voice and internet running. Confirm the coverage and service-term wording at quote stage.
Can I use Screamer for Microsoft Teams calling?
Yes. Teams calling sits in Screamer’s voice catalogue alongside hosted PBX and the standalone line. The SBC delivery model and Microsoft 365 plan scope are set at quote, which suits buyers wanting Teams calling from the same operator as their connectivity.
What areas does Screamer cover?
Coverage is Gauteng-anchored, with national reach on selected product lines. Availability is confirmed per premises, so an address check establishes which combination of fibre, wireless WAN or LTE/5G reaches your site before you commit.
