What Is Business VoIP and Why SA Businesses Are Switching
VoIP (Voice over Internet Protocol) routes your phone calls over your internet connection instead of the old copper telephone network. Your calls sound identical — but you pay a fraction of the price.
South African businesses spent an average of R3,200/month on 8 Telkom landlines in 2025. The same 8 lines on VoIP: R600–R900/month. That's a saving of R2,300+/month, or R27,600/year.
The shift accelerated when Telkom stopped investing in copper infrastructure. Load shedding killed landlines (they need municipal power), while VoIP on fibre with a UPS just keeps working.

How to Set Up VoIP for Your Business in South Africa
Most businesses are live within 4 hours. Here's the process:
1. Check your internet speed — You need at least 1 Mbps upload per simultaneous call. A 10/10 fibre line handles 8–10 concurrent calls with ease. MWCom can supply the fibre and VoIP from a single account.
2. Choose your number type — Keep your existing 010/011/021 number (porting takes 5–10 business days) or get a new VoIP number instantly. Geographic numbers available for Johannesburg (011), Cape Town (021), Durban (031).
3. Get your VoIP phones or softphones — Physical IP phones (Yealink, Grandstream) cost R500–R2,000. Free softphone apps (Zoiper, MicroSIP) work on any PC or smartphone — useful during load shedding if your PC is on a UPS.
4. Configure and test — MWCom provisions the SIP credentials and walks you through the setup. Most small businesses are fully live before lunch on day one.
Load Shedding and VoIP: What Nobody Tells You
VoIP relies on your internet connection — and your internet relies on power. Without a UPS, VoIP goes down during load shedding, just like everything else.
The solution: a small UPS (R800–R1,500) on your router and VoIP phones keeps calls running for 2–4 hours during Stage 2–4 load shedding. MWCom customers on our business fibre routes get priority restoration from the fibre network side.
Mobile softphones are your backup. Configure Zoiper on your cell — it rings simultaneously with your desk phone, so you never miss a call during an outage.
VoIP Features Every SA Business Needs
- IVR / Auto-attendant — "Press 1 for sales, 2 for support" — without a dedicated receptionist
- Call queuing — Customers hear hold music instead of a busy signal
- Voicemail to email — Missed calls arrive in your inbox as MP3 files
- Call recording — Required for some industries under POPIA if calls contain personal data
- Hunt groups — Ring multiple phones simultaneously (main reception)
- Number portability — Keep your existing 010/011 number when you switch
Is VoIP Reliable Enough for Business?
With a decent internet connection, yes. Call quality on a properly configured VoIP system is indistinguishable from a landline. The key variables are:
Jitter — variations in packet timing that cause choppy audio. Fixed with QoS settings on your router that prioritise voice traffic. MWCom configures this for you on managed connections.
Latency — anything under 150ms is transparent. SA fibre connections typically hit 8–20ms to local exchanges. International calls have more latency but are still clear.
Bandwidth — 100 kbps per call is plenty. A standard 10 Mbps business line handles 50 simultaneous calls.
Frequently Asked Questions
Can I keep my existing phone number when switching to VoIP?
Yes. Number porting from Telkom or another provider takes 5–10 business days. During porting, your old number continues to work. MWCom handles the porting process — you just fill in a form.
Does VoIP work without the internet?
No — VoIP requires an active internet connection. During load shedding, a UPS on your router keeps VoIP working. Alternatively, you can configure a mobile softphone (Zoiper) as a failover for cellular calls at VoIP rates.
How much does VoIP save compared to Telkom?
Most SA businesses save 40–60% on monthly phone costs. A business spending R3,200/month on Telkom landlines typically pays R900–R1,400/month for equivalent VoIP lines — saving R1,800–R2,300/month.
Is VoIP POPIA compliant in South Africa?
VoIP itself is not inherently non-compliant. If you record calls (for quality or training purposes), you must notify callers per POPIA and store recordings securely. MWCom's call recording feature includes built-in disclosure tones and encrypted storage.
How long does VoIP setup take?
4–8 hours for most businesses. If you need to port existing numbers, allow 5–10 business days. New VoIP numbers are provisioned within 1 hour.
What internet speed do I need for VoIP?
1 Mbps upload per simultaneous call. A 10 Mbps symmetric fibre line handles 8–10 concurrent calls. For a call centre or busy reception desk, consider a 20–50 Mbps line. MWCom can advise based on your call volume.
Can I use VoIP on my mobile phone?
Yes. Softphone apps like Zoiper (free) or the MWCom mobile app run on Android and iPhone. You can use your business number on your cell — ideal for remote staff or as a load shedding backup.
