For decades, South African businesses relied on traditional landline systems to stay connected. But while landlines feel familiar, they're often far more expensive and restrictive than most SMEs realise.
Today, Voice over Internet Protocol (VoIP) is quickly replacing landlines, offering predictable pricing, advanced features, and the flexibility that modern businesses need. Yet many SMEs stick with outdated systems because they're unaware of the hidden costs buried in landline bills.
Let's unpack those hidden costs and explain why so many South African businesses are making the switch to VoIP.
The True Cost of Landlines
Traditional phone systems seem straightforward: pay for line rental, make calls, and pay per minute. But the reality is more complex — and more expensive.
1. Line Rental Fees
Every landline number comes with a monthly rental charge. For SMEs with multiple lines, these fees add up quickly, even if the lines are rarely used.
2. High Call Rates
Landlines still charge per minute for local, national, and international calls. According to Telkom Wholesale, these rates remain significantly higher than VoIP alternatives.
3. Hardware & Maintenance Costs
On-site PBX systems require installation, upgrades, and regular technician visits. This hardware is expensive to maintain and often needs replacing every few years.
4. Add-On Charges for Features
Want call forwarding, voicemail, or conferencing? On landline systems, these often come with extra charges. VoIP includes them by default.
5. Lack of Scalability
Adding new lines isn't just costly — it's time-consuming, requiring physical infrastructure changes.
These hidden costs make landlines unsustainable for SMEs that need affordability and flexibility.

Landline vs VoIP: Side-by-Side Comparison
| Aspect | Landlines | VoIP (SureTel) |
|---|---|---|
| Monthly Fees | Line rental + usage charges | Fixed monthly cost |

The Bigger Picture: Business Productivity
It's not just about cost. Landlines hurt productivity in ways SMEs can't afford:
- Downtime: A damaged line means no calls until repairs are made.
- Missed Opportunities: No voicemail-to-email means missed customer messages.
- Inefficiency: Lack of call routing or analytics makes customer service slower.
As MyBroadband reports, South African SMEs are increasingly frustrated with unreliable providers and outdated systems.
