Yeastar — business phone system platform in South Africa
Yeastar is a business phone system platform with global operations headquartered in Xiamen, China, best known for its P-Series PBX. It runs four ways — on-premise appliance, Yeastar-hosted cloud, self-hosted software or your own cloud — with unified communications and contact-centre features on one platform. In South Africa it is sold and supported through resellers rather than directly, so you can pick a deployment that fits and switch later.

Yeastar’s draw is deployment flexibility on the P-Series
Yeastar is a phone system platform rather than a South African voice carrier, and its distinguishing feature is choice of deployment: the same P-Series can run as an on-premise appliance, on Yeastar’s hosted cloud, as self-hosted software or on your own cloud. That suits businesses that want to start one way and move later without changing platform. In South Africa you buy through resellers, who pair the system with a licensed voice carrier and supply ICASA Type-Approved hardware. The question to weigh is whether owning and placing the platform yourself beats a fully managed hosted service where the provider runs everything.
Who Yeastar is a fit for
- SA businesses wanting one phone-system platform that can run on-premise, hosted or self-hosted, and switch between them as needs change.
- Buyers who want a physical on-premise appliance option rather than a cloud-only service.
- Teams wanting UC and contact-centre features with control over where the system lives.
