What is WhichVoIP?

WhichVoIP is a South African comparison site for business telecoms. It scores cloud PBX phone systems, business VoIP and AI voice agents, plus business fibre, wireless and call-centre providers, out of 10 on one public rubric: pricing and value, features, customer reviews, reliability and support. Every published price links to its source and the date it was read.

Businesses compare providers for free and can request quotes from up to three that serve their size and province. Providers pay to receive those requests. They can’t buy a score, a rank or a verdict, and every sponsor is labelled.

Before you sign

36 months is a long time to find out.

Many business phone and internet contracts run 24 or 36 months. The monthly fee is only part of the bill: call rates, handsets, setup and the line underneath all land on it. See every part before you sign.

Where the money goes: VoIP lines vs a cloud PBX

YOU BUY VOIP LINES YOU BUY A CLOUD PBX Your desks handsets, softphones Your phone system you own, host and fix it SIP trunk channels, not users The network calls in and out Your desks handsets, softphones The provider’s Cloud PBX extensions · IVR · call recording · hunt groups · trunk priced per extension, from R26 to R185 a month The network calls in and out

The orange box is the whole decision. Own it and you carry the upgrades, the licences and the 2am call; rent it and you pay per extension every month instead.

Trust

Why this list is worth trusting.

Most “best provider” lists you’ll find are written by a provider on the list. Ours isn’t. Providers pay to receive matched quote requests, and sponsored partners are labelled wherever they appear. Nobody can buy a score, a rank or a verdict.

  • Same rules for sponsorsA sponsor is scored on the same five measures as everyone else.
  • Labelled wherever they appearIf money changes hands, you see the Sponsor label next to the name.
  • Corrections are freeAccuracy corrections are free, sponsor or not.

Straight answers

Questions buyers ask us first

What does a cloud phone system cost in South Africa?
Published entry prices start at R26 per extension per month (Switch Telecom, sold in 10-extension blocks, month-to-month). Many providers only quote. The phone system comparison lists every published price with its source and the date we read it.
Is WhichVoIP free to use?
Yes, for buyers. Reviews, scores and comparisons are open, and quote requests cost nothing. Providers pay to receive matched quote requests. That pays for the site; it doesn’t buy a score.
How many quotes will I get?
Up to three, from providers who serve businesses your size in your province. Then the request closes, so your phone doesn’t ring for weeks. If no provider covers your size or area, we come back to you ourselves.
Can a provider pay for a better score?
No. Every provider is scored on the same public rubric. Sponsors are labelled wherever they appear, and a score only moves when the evidence does.
What's the difference between VoIP and a cloud PBX?
VoIP is the line; a cloud PBX is the switchboard on top of it. Buy VoIP lines if you already have a phone system that needs dial tone. Buy a cloud PBX if you need extensions, menus, call recording and hunt groups hosted for you.
Can I keep my existing phone numbers?
Yes. Number porting is a legal right in South Africa. Confirm the porting fee and timeline in writing before you sign, because both vary by provider.
How is a WhichVoIP score calculated?
Five scores out of 10: pricing and value, features, customer reviews, reliability and support. They are published separately, so you can read the shape, not just the number. Every price and fact behind a score carries a source link and the date it was read.
Do you cover residential telecoms too?
No, this is business telecoms only. Scoring weighs business SLAs, support escalation and contract terms that residential packages don’t carry. Some providers here also sell to households, but the scores reflect their business offering.
I'm a provider. How do I get listed?
Listing, reviewing and scoring are free and open to any licensed South African provider, and they can’t be bought. Receiving matched quote requests is a separate, paid arrangement that is labelled on the page. See the terms.

For providers

Sponsored partners get disclosed presence where buyers decide. Nobody gets a better score.
