This is stage 2 of the buying journey. If you still want the basics — what a Cloud PBX is, what it should cost, and how it differs from VoIP — start with the Cloud PBX guide. If you already know what you need, filter the table by team size, shortlist two or three providers, and we'll match you with quotes.

Comparison price is the entry-tier price per extension, excluding 15% VAT, shown alongside each provider’s verbatim published price. Mandatory add-ons such as SIP trunks are listed separately and are not folded into this figure. Quote-based providers are shown as quote-based. All rand prices and call rates on this page exclude 15% VAT. Prices published in euro are converted at the ECB reference rate of €1 = R19.04 (31 July 2026) and shown as estimates.
A 10-seat Cloud PBX costs R260 to R1,850 a month in seat fees on this table, before call charges and VAT.
3. How to choose a Cloud PBX provider in South Africa
Six checks, in the order they save you money. Every number below comes from the comparison table above, so you can verify it as you go.
1. Start with your actual call volume
Cloud PBX pricing in South Africa follows two models: a flat seat fee (R26 to R185 per user or extension a month on this table) plus per-minute call charges, or pay-as-you-go billing with no seat fee at all (Axxess). If your team makes fewer than 200 outbound minutes per user a month, the seat fee decides the bill. If it makes more, the published call rates in the table matter more than the seat price — and note that several providers only quote rates rather than publish them. Ask each shortlisted provider for a cost projection on your real call data; any decent provider will do this free of charge.
2. Check load shedding resilience
A Cloud PBX stays online during load shedding because it runs in a data centre with backup power — but your office does not. The best providers offer automatic failover to mobile numbers, a mobile app that takes calls over cellular data, and UPS-backed infrastructure. If a provider cannot clearly explain what happens to your inbound calls during Stage 4, walk away.
3. Understand contract lock-in
Four of the twelve providers here bill month-to-month: Switch Telecom, United Telecoms, Vox Telecom (OmniOne) and NoPBX. Telkom Business asks for 12, 24 or 36 months, and 3CX is an annual software licence on its paid tiers. Month-to-month sometimes costs a little more, but it lets you leave if service deteriorates. If you do sign a term, negotiate a 30-day exit clause for sustained SLA breaches.
4. Don't overvalue features you won't use
The features most SA businesses actually use are IVR (auto attendant), call recording, voicemail-to-email, ring groups and a mobile app — the Key Features column in the table. CRM integration, wallboards, API access and AI transcription are worth paying for only if your workflow demands them. A 5-person law firm does not need call centre wallboards; a 50-seat sales floor does.
5. Test before you commit
Most reputable providers offer a trial or pilot. Use it: test call quality between 10am and 12pm (SA's busiest calling window), test the mobile app during load shedding, and phone support at 4pm on a Friday. If they cannot handle you as a prospect, they will not handle you as a customer. Our provider reviews record real customer feedback on support response times.
6. Verify the ICASA licence
Any provider offering voice services in South Africa must hold ICASA ECNS and ECS licences. Every provider listed on WhichVoIP has been verified as licensed. If you are evaluating one that is not on this page, ask for the licence number and check it on the ICASA website.
✓
The short version: price on total monthly cost for your real call volume, prefer month-to-month or a 30-day SLA exit, and test the mobile app during load shedding before you sign.

Compare like for like: every price on this page excludes 15% VAT, and Switch Telecom and 3CX price the seat without the SIP trunk — add the trunk (from R100 for 4 channels at Switch; partner-supplied for 3CX) before you compare totals.
4. How we score Cloud PBX providers
WhichVoIP's ratings are calculated using a weighted scoring model across five dimensions. Every provider is evaluated using the same criteria, and no provider can pay for a higher score or a higher position in the comparison table. Sponsored partners are shown first, and labelled as such, in the top picks above the table. Our revenue comes from connecting businesses with providers — not from providers buying visibility.

5. Frequently asked questions
What is the cheapest Cloud PBX in South Africa?▼
As of September 2026, the most affordable Cloud PBX option in South Africa is 3CX, which offers a free tier for up to 10 users. For a fully hosted solution, Switch Telecom has the lowest verified seat price at R26 per extension per month, sold in blocks of ten (R260 per block). Switch prices seats and SIP trunks separately, so add a trunk from R100 for 4 concurrent channels — you size channels to your call concurrency, not to your headcount, so a 30-seat site may still only need 4 to 8 channels. All prices on this page exclude 15% VAT. However, the cheapest option depends on your call volume — providers with low base fees but high per-minute rates can cost more than a premium plan if your team makes hundreds of calls daily. WhichVoIP recommends getting quotes from at least two providers based on your actual monthly call volume for an accurate comparison.
Does Cloud PBX work during load shedding?▼
A Cloud PBX system itself stays online during load shedding because it's hosted in a data centre with backup power. However, your ability to make and receive calls depends on your local internet connection and power. If your router goes down, so do your desk phones. The workaround: most Cloud PBX providers offer a mobile app (softphone) that lets you take business calls on your cellphone using mobile data. United Telecoms and NoPBX both include mobile apps. Some providers also offer automatic call forwarding to mobile numbers when your office connection drops. When evaluating providers, ask specifically: "What happens to incoming calls during a power outage at our office?"
What's the difference between Cloud PBX and VoIP?▼
VoIP (Voice over Internet Protocol) is the underlying technology that transmits voice calls over the internet instead of traditional phone lines. Cloud PBX is a complete business phone system that uses VoIP as its foundation but adds enterprise features: auto-attendant menus, call routing, extensions, ring groups, call recording, and voicemail-to-email. Think of it this way — VoIP is the engine, and Cloud PBX is the entire car. If you just need to make cheap calls, a basic VoIP service or SIP trunk is enough. If you need a professional phone system with multiple extensions and call management, you need Cloud PBX.
Can I keep my existing phone number when switching to Cloud PBX?▼
Yes, in most cases. The process is called number porting, and all major South African Cloud PBX providers support it. Porting a number typically takes 5–10 business days in South Africa, depending on the losing carrier. Geographic numbers (011, 021, 031, etc.) and national numbers (010, 087) can both be ported. The porting process is managed by your new provider — you'll need to provide your current service agreement details and a letter of authority. There's usually no cost for porting, though some providers charge a once-off R250–R500 activation fee per number. During the transition, a good provider will set up temporary call forwarding so you don't miss calls.
How much internet bandwidth do I need for Cloud PBX?▼
Each concurrent call on a Cloud PBX system uses approximately 100 Kbps (0.1 Mbps) of bandwidth in each direction using the standard G.711 codec. For a 10-person office where up to 5 people might be on calls simultaneously, you'd need at least 1 Mbps of dedicated bandwidth — though 2–5 Mbps is recommended for comfort. Most South African fibre connections (10 Mbps and above) handle Cloud PBX without issues. The bigger concern is latency and jitter, not raw speed. A stable 10 Mbps fibre line will deliver better call quality than an unstable 50 Mbps connection. If you're on wireless (LTE/5G), Cloud PBX will work but call quality may fluctuate during network congestion.
Do I need to buy new phones for Cloud PBX?▼
Not necessarily. You have three options: use IP desk phones (Yealink, Grandstream, Poly — from R800–R3,000 each), use softphones on your computer (free software), or use mobile apps on your smartphone (included by most providers). Many businesses start with softphones and mobile apps, which cost nothing extra, and only buy desk phones for reception or staff who prefer physical handsets. If you already own SIP-compatible IP phones, they'll likely work with any Cloud PBX provider — just ask your new provider to confirm compatibility with your specific model. Avoid buying phones before choosing a provider, as some offer rental or subsidised handsets.
Is Cloud PBX secure? Can calls be intercepted?▼
Modern Cloud PBX systems use TLS encryption for signalling and SRTP encryption for voice traffic, making call interception extremely difficult. Reputable providers also implement firewall protection, intrusion detection, and regular security audits. The main security risks are weak passwords on extensions (which can lead to toll fraud) and unsecured network configurations. When evaluating a provider, ask whether they offer TLS/SRTP as standard, whether they monitor for unusual call patterns (toll fraud detection), and where their data centres are located. Providers hosting locally in South Africa keep your voice data under SA jurisdiction, which may matter for POPIA compliance.
What happens if my Cloud PBX provider goes out of business?▼
This is a legitimate concern, especially with smaller providers. If your Cloud PBX provider shuts down, your service stops and you'll need to port your numbers to a new provider — which can take 5–10 business days, during which you could lose incoming calls. To protect yourself: choose providers with a track record of at least 5 years in the SA market, avoid paying more than 1 month in advance, and always have your number porting details readily available. Keeping a backup mobile number that customers know is also sensible. WhichVoIP only lists providers that are ICASA-licensed and have demonstrated financial stability, but we always recommend month-to-month contracts for maximum flexibility.
