What is Multi-Tanent PBX?
Traditional PBX models need one system for each client. This makes them expensive and difficult to scale for providers with many clients. Some vendors provide multi-tenant PBX on a shared system. However, this often leads to limited customization and poor resource separation. There is also a risk that problems can affect multiple tenants.
Yeastar takes it further.
Our multi-instance PBX solution runs separate PBX systems on a central hub. Each instance is secure, customizable, and centrally managed, while sharing key resources like concurrent calls and extensions. It offers the best of both worlds: isolated and flexible instances with high efficiency and lower costs.
Centralized Management of Multi-Tenant PBX Made Simple
Yeastar Central Management (YCM) is your control center for remote deployment, maintenance, and monitoring. It helps reduce support overhead, speed up response, and scale service with less manual work.

Common Questions about Multi-Tenant PBX
What's the difference between Multi-Tenant and Multi-Instance PBX?
Multi-Instance means hosting independent instance for each PBX system, with isolated environments but higher resource usage and complexity.
Multi-Tenant runs multiple fully-isolated PBXs on one shared instance. It simplifies management, reduces cost, and with scale ability.
Yeastar’s Approach: We separate each tenant on one PBX Hub within one server. Every client gets a fully independent PBX with enterprise-grade features, secured environments, and centralized management—streamlining delivery without compromising isolation.
Can I integrate local platforms with the Yeastar PBX system?
Absolutely. Yeastar works with popular platforms such as Microsoft Teams, WhatsApp, and Salesforce. It also offers strong open APIs. This lets you easily connect with your favorite local CRM, billing, or communication platforms. This works for one PBX or many tenants. The integration is flexible and scalable, helping service providers localize faster, enrich client services, and build stronger customer loyalty.
Can I use my own SIP trunk and customize the call flow?
Yes. Yeastar support bring your own carriers (BYOC). You can bring your own SIP trunk, manage phone numbers, and build your own call flow logic per tenant. Unsure where to begin? Check our list of certified global SIP trunk providers to ensure compatibility and optimal quality.
