The 8 cheapest VoIP providers, one at a time

Eight South African providers, in the order their own published pricing puts them. Three of them currently treat the entry fee as a sales-call question, which is itself a useful filter.

1. Vox Vobi: cheapest published monthly entry

Entry tier: R29/month (per-minute, 2 users) · Unlimited tier: R149/month (single user) · VAT: inclusive · Contract: month-to-month.

Vobi is a mobile softphone app (iOS and Android) from Vox Telecom. The R29 per-minute plan supports up to two users on one account at a flat 46c per minute to every SA number, landline or mobile. R149 unlimited replaces the per-minute meter with all-you-can-call SA minutes for a single user. Both plans are VAT-inclusive on the published pricing page, which is rare in this market.

What Vobi is not: a hosted PBX. There is no IVR, no hunt groups and no extension management. If you need anything more than a phone number on a mobile app, look further down the list.

2. Axxess VoIP: CallTime for existing Axxess clients

Entry tier: R50/month CallTime · VAT: inclusive · Devices: up to 6 per account · Contract: none.

Axxess VoIP works as a prepaid CallTime balance: R50, R100, R300 or R500 per month, with unused minutes rolling over for three months. Calls to other Axxess VoIP numbers are free, as are calls to anything on the CTEL network (which means Afrihost Pure VoIP is also free, since both ride the same wholesale platform). Telkom local and national calls run at 40c per minute; mobile is 80c per minute, billed per second after the minimum.

The fit is obvious if your business is already on Axxess fibre or LTE: one provider, one invoice, one support line. If you are not, the maths is essentially identical to Afrihost below.

3. Afrihost Pure VoIP: the closest mainstream equivalent

Entry tier: R51/month (VoIP 50) · VAT: excluded · Devices: up to 6 per account · Porting: R99 once-off.

Pure VoIP is Afrihost’s CallTime answer: VoIP 50, 100, 300 and 500 buy that rand value of CallTime per month, with three-month rollover on anything you do not use. Free calls between Pure VoIP numbers and free calls across the CTEL network (Axxess included). Telkom local 40c, mobile 80c per minute, with per-second billing after the minimum.

Where it differs from Axxess: Afrihost’s published rates are ex VAT, so the headline R51 grosses up to roughly R59 once VAT is added. Porting an existing landline carries a R99 once-off admin fee, materially less than the R150 to R250 some other providers charge.

4. Switch Telecom: the cheapest hosted PBX in the table

VoIP Line: from R52/month · Hosted Switchboard: R260 per 10-extension block (R26/ext) plus a SIP trunk from R100, about R36/ext all in · Contract: month-to-month · Installation: free.

Switch Telecom has two relevant offers. For a simple single-line replacement, the VoIP Line tier starts at R52/month and includes free installation. The more interesting number is the Hosted Switchboard product: R260 buys a 10-extension block, which works out at R26 per extension and is the lowest published Cloud PBX figure on this list. The trade-off is that you buy in 10-ext blocks, so a five-person team pays for 10. Switch Telecom flagged a 2026 service-fee adjustment after 18 years of holding prices flat, so confirm the figure at signup.

Per-minute call rates also tend to come in low: local geographic calls in the high-20c range, mobile in the mid-40c range on Switch Telecom’s published rate card. The 2026 review on WhichVoIP’s Switch Telecom review has the full call-rate breakdown.

5. Euphoria Telecom: full-feature Cloud PBX, fewer surprises

Express: R65/ext/month · Enterprise: R85/ext · Call Buster: R185/ext (29c/min calls included) · Contact Centre: R295/agent · Setup: R1,500 base + R65/ext · VAT: excluded.

Euphoria Telecom’s published pricing recently moved up from the R45 figure that older roundups still cite to R65/ext on the Express tier. The headline number is no longer the cheapest in this table, but the entry plan includes IVR, queues and ring groups, after-hours routing, voicemail-to-email, real-time monitoring, softphone and browser phone, and integrations into Zendesk, Zoho, Freshdesk and Microsoft Teams. The Call Buster plan is the interesting one if call volume is the bill killer: R185/ext with 29c per minute baked in.

Euphoria runs its own platform rather than reselling. That matters because the feature roadmap is internal to one team and the support escalation path is a single org. Cancel any time before the 23rd of the month and the contract ends; no notice period to negotiate.

6. Centracom: bundled voice, fibre and hardware (quote only)

Entry tier: contact for quote · Differentiator: 50+ connectivity providers under one account.

Centracom’s site is open about what they do (hosted PBX, tier-1 VoIP, 50-plus connectivity options) but not about what it costs. There is no published monthly figure to verify. We are leaving Centracom in this comparison because the bundled-voice-plus-fibre angle is genuinely useful for a single-vendor procurement decision, but be aware that you cannot pre-screen the price on the website. Ask for the rate card and the per-second billing terms in the same email.

7. Telviva: UCaaS bundle, Microsoft Teams direct routing

Plans: Telviva One Essentials, Telviva One Premium · Bundles: Talk 500 (1–5), Talk 1000 (6–10), Talk 2000 (11–20) · Remote setup: R1,500.

Telviva (the former Connection Telecom, rebranded in 2017) does not publish a per-user monthly figure on its UCaaS pricing page. What is visible is the package structure: two per-user tiers (Essentials and Premium, both quote-driven) plus three bundles sized for 5, 10 and 20 users that include 500, 1,000 or 2,000 SA-destination minutes respectively. Setup is R1,500 for remote installs.

The “cheapest” framing does not really fit Telviva. The product is a unified-communications platform that bundles voice, video, messaging, presence and Microsoft Teams direct routing into one subscription. For a Teams-first team that needs proper telephony hooked into the existing collaboration stack, Telviva is the option that earns its monthly fee even at a higher per-user price point.

8. Wanatel: resellers, MSPs and white-label deployments

Entry tier: quote only · Notice period: 30 days · Differentiator: KEVO reseller programme.

Wanatel’s site is heavy on capability and light on price. The Cloud PBX is a multi-tenant platform with handset auto-provisioning, an integrated billing module, a call-quality analysis tool and full white-label support for resellers, plus the KEVO programme for partners building their own VoIP business. Standard features include IVR, hunt lists, call recording, queue management and an operator panel.

If your need is “we are an IT services company and we want to sell VoIP under our own brand”, Wanatel is one of the few SA platforms purpose-built for that. If your need is “we are a 12-person office that just wants a phone system”, the providers above will probably price up lower.

What “cheapest” really means once the line is live

Three things determine your bill more than the headline subscription. Get them wrong and a R29 plan can cost more than a R149 one.

• Call rates versus included minutes. A R29 PAYG plan at 46c/min costs R275 if you use 600 minutes. A R149 unlimited tier covers the same 600 minutes for nothing extra. Estimate average minutes per user before choosing a tier.
• Per-second versus per-minute billing. Per-second billing (Axxess, Afrihost, Switch Telecom and Centracom all offer it) bills a 10-second call as 10 seconds. Per-minute billing rounds the same call up to a full minute. For a sales team running 200 short calls a day, that is a 20 to 30 percent difference in the call total.
• VAT discipline. Half the providers in this table quote ex VAT and half quote VAT-inclusive. Always normalise both sides of a comparison to the same VAT treatment before signing.

Setup, porting and other once-off fees

Most providers in this list publish setup and porting fees somewhere on the site, but they are easy to miss until the first invoice. Euphoria Telecom’s setup is R1,500 base plus R65 per extension, so a 10-person office is R2,150 once-off. Switch Telecom installs the VoIP Line tier free. Afrihost’s port admin fee is R99 once-off; Axxess does not charge a port fee. Telviva’s remote setup is R1,500. Ask for the full once-off list, not just the monthly figure.

What a 10-person office actually pays

A worked example for a typical SA team making 2,000 minutes of local and 500 minutes of mobile calls per month. Verifiable rates only, ex VAT, May 2026.

The pattern repeats across most office sizes: switching off a traditional Telkom landline stack to almost any VoIP provider on this list saves R3,000 to R3,500 a month for a 10-person team. That is R36,000 to R42,000 a year before any of the productivity gains (mobile, softphone, click-to-dial, integrations) get counted.
