Business Phone Systems
Without the Telkom Bill.
VoIP phone systems engineered to cut call costs. Cloud or on-premise PABX, auto-attendant, call recording, mobile app, and CRM integration.
Why VoIP
What is VoIP?
Voice over IP (VoIP) sends your phone calls over the internet instead of traditional phone lines. The result is dramatically lower costs, better call quality, and features that traditional PABX systems charge thousands for.
South African businesses are switching to VoIP in record numbers. With Telkom line rental at R150–R350/month per line plus per-minute charges, the savings are immediate and substantial. VoIP also enables remote work — your team can take calls from anywhere with an internet connection.

- Unlimited local calls on all plans

FAQ
VoIP Questions Answered
Do I need special phones for VoIP?
No. You can use SIP-compatible desk phones (from R500), our mobile app on iOS/Android, or a softphone on your computer. Most modern IP phones work with our system.
How much can I save compared to Telkom?
Most businesses save 50–70% on monthly call costs. Line rental drops from R150–R350/line to R15–R99/user. Local calls are included. International calls drop from R5–R20/min to R0.50–R2/min.
Will my existing numbers work?
Yes. We handle number porting for South African landline and mobile numbers. The process takes 5–10 business days and we manage the entire transition with zero downtime.
Can I keep my business running during the switch?
Absolutely. We set up the new VoIP system in parallel with your existing phones. Once everything is tested and confirmed, we port the numbers. No downtime, no lost calls.
What internet speed do I need for VoIP?
Each concurrent call needs approximately 100 Kbps. For 10 simultaneous calls, you need about 1 Mbps. Any fibre or wireless connection from GTL is more than sufficient.
Do you offer call centre solutions?
Yes. Our Enterprise plan includes IVR, queue management, skill-based routing, call recording, real-time analytics, and agent dashboards. Pay per seat, scale on demand.
