When installed in multi-tenant mode, the ucplus Server can be configured to contain partitions or tenants that are each dedicated to a single end customer.

What is a Tenant?

In the context of a ucplus installation, a Tenant would be a single end user customer, with one of more sites each using ucplus client software.

Why Install a Multi-tenant Server

There is an increasing demand for hosted deployments, where a single telephone system is shared across multiple end customers. Installing the ucplus Server in multi-tenant mode allows a single ucplus Server and its associated licenses to be shared across multiple end customers, reducing hardware and software costs.


Multitenant architecture


The multi-tenant capability is contained within the normal ucplus Server, i.e. there is no additional software to download. The multi-tenant functionality is enabled simply by loading a tenant license on the server in the same way any other license is loaded. Client connections consume licenses from a single pool of licenses in the normal way except an additional setting restricts each tenant to a maximum number of each licenses type.

To set up a multi-tenant server, one of the two starter packs available must initially be purchased. Individual tenant licenses can only be purchased once a starter pack has been purchased and installed. All other ucplus licenses can be purchased and added in the normal manner.


The ucplus multi-tenant server is designed so that users within one tenant are completely separated from users configured in other tenants.

Other Configurations

The ucplus Server also has the flexibility to work with multiple single tenant telephone systems and / or handsets supporting uaCSTA.

Multiple single-tenant telephone systems

Multiple Single-tenant PBX example

Using uaCSTA Handsets as the PBX Type

Shown above the ucplus Server would typically connect to the telephone system using a CTI connection (CSTA / TAPI etc). The ucplus Server also supports a mode known as uaCSTA where, instead of connecting to the telephone system, the handsets register with the ucplus Server directly. In this mode the solution can be deployed regardless of the telephone system type as long as the handsets deployed support uaCSTA.
