VoIP vs a landline for a South African small business
Most South African small businesses asking this question are really asking two things: will it cost less, and will it be reliable? Those have different answers, so it is worth separating them.
A traditional business landline bills in two parts: a fixed monthly line rental for the physical connection, plus per-minute call charges on top. The rental is charged whether you make calls or not.
A VoIP line rides on the internet connection you already pay for, so there is no separate copper line to rent. Hopetel bundles minutes into the monthly price — R250/month includes 150 minutes, R410 includes 500, R550 includes 1 000.
We have deliberately not published competitor prices here. Line rental and per-minute rates change and vary by package, and quoting numbers we cannot verify would be worse than useless. Take your last two invoices, add rental plus call charges, and compare that total against a bundled monthly price.

Where a landline still genuinely wins
Being straight about this matters more than winning the argument:
Unreliable internet. If your connection drops regularly and you have no backup, a landline is more dependable. VoIP quality is only as good as the connection under it.
Frequent, long power outages with no backup power. A basic corded analogue phone draws power from the exchange. VoIP does not.
Certain alarm and lift lines. Some legacy equipment expects an analogue line. Check with the provider before switching anything safety-related.
Both of the first two are solvable — see our load-shedding guide — but they are real considerations, not marketing objections.
A simple way to decide
Add your last three months of line rental plus call charges and divide by three.
Count the minutes you actually use per month.
Match that to a bundled plan — 150, 500 or 1 000 minutes.
Ask honestly how stable your internet is, and whether you have backup power.
If the internet is stable and you have some backup power, VoIP is usually both cheaper and more flexible. If neither is true, fix that first.
Frequently asked questions
Is VoIP cheaper than a landline in South Africa?+
Usually, because there is no separate line rental and minutes are bundled. The honest way to check is to total your current rental plus call charges and compare against a bundled monthly plan.
Does VoIP work during load-shedding?+
Only if your router and phone have power. A small UPS on the router plus a softphone app on a charged mobile keeps the line running. A basic corded analogue landline does not need local power.
Can I keep my existing number if I move to VoIP?+
Yes. Porting costs R250 once-off and typically takes about 3 working days, and geographic numbers keep their area code.
How much internet does a VoIP call use?+
A single call uses very little bandwidth — far less than video streaming. Connection stability matters more than raw speed.
Do I need special hardware for VoIP?+
No. A softphone app on a phone or laptop is enough to start. Desk phones are optional if you prefer a handset.
