Multi tenant platform

A multi-tenant PBX is a modern PBX that utilizes VoIP technology and is designed to support multiple tenants, on a single platform. It helps in establishing a centralized control by allowing modification at different levels of usage permission for multiple users/tenants.

PortSIP PBX is a high-performance PBX that can handle up to 10,000 concurrent calls per server.

A full white label solution

White label solutions refer to products or services that are created by one company for the purpose of being sold by another company under that company’s own unique branding.

Using the white label reseller business model, the second company slaps their own label over the blank (or “white”) label and resells the solution to their clients, who are never the wiser.
