iOT Voice — cloud PBX and SIP provider in South Africa
iOT Voice sells cloud voice, SIP trunking and call centre capability to South African businesses, alongside home phone lines, business PBX systems, cloud dialler tools and a wholesale voice product for reseller partners.

Retail and wholesale from one platform
Selling cloud PBX to an office, a home line to a household and wholesale voice to other resellers is a wide span for a provider of this size, and it is worth understanding which of those you would be. A wholesale relationship is priced by committed volume and expects you to handle your own customers; a retail one comes with support. Ask which side of the business you would sit on and what support that carries. The dialler tools alongside SIP trunking point at call centre customers as a meaningful segment. Two things need pinning down before a decision: the phrase powered by ICASA-licensed infrastructure describes someone else’s licence rather than necessarily their own, so ask whose it is; and no pricing or Google profile exists to check, so ask for recent reference customers. Compare alternatives in the cloud PBX directory.
Who iOT Voice is a fit for
- Resellers wanting a wholesale voice supplier rather than a retail account
- Call centres needing SIP trunking with dialler tooling
- Businesses wanting cloud PBX and home lines from one provider

What does “powered by ICASA-licensed infrastructure” mean?
It describes the network the service runs on rather than necessarily a licence the company holds itself. Ask whose licence it is and request the reference in writing if your procurement process records it.
Does iOT Voice sell wholesale?
Yes. Wholesale voice for reseller partners is listed alongside the retail products. That is a different relationship, usually priced by committed volume and without the support a retail account carries. Ask which side you would be on.
What are cloud dialler tools?
They are software for placing outbound calls automatically at scale, used by call centres running campaigns. Ask which dialling modes are supported and how they are licensed, since that determines whether the platform suits campaign work.
Why is no customer rating shown?
No Google Business Profile could be found for this business. Searches return IoT.nxt, an unrelated Centurion software company, which WhichVoIP did not use. Ask for reference customers instead.
What does it cost?
No pricing is published for any product. Ask for the per-extension charge, per-minute rates to landline and mobile, and any wholesale committed-volume pricing as separate figures.
How long has iOT Voice been trading?
No founding year is published, so WhichVoIP does not state one. Ask for company registration details if trading history matters to your evaluation.
