Deliver amazing experiences using PortSIP
The powerful multi-tenant PBX unleashes modern features, performance optimization, flexibility, and scalability to empower businesses of all sizes to enhance employee experiences, resulting in improved customer experiences.
Streamlined unified communication
Users can communicate effectively, no matter where they are by seamlessly transitioning among communication channels—including calls, messaging, and meetings—all on a single platform.
Simplified administration
PortSIP PBX provides a unified platform that allows PBX system administrators, tenant administrators, and dealers to efficiently manage tenants and extensions from a single, centralized interface.
All-in-one, out-of-the-box solution
Hundreds of unified communication features—like call routing, SMS, WhatsApp, team messaging, contact center, and voice and video meetings—all in one powerful multi-tenant PBX that runs on your infrastructure or on Azure, AWS, GCE.
Only true Multi-Tenant PBX
Unlike other pseudo multi-tenant PBXs, which are actually multiple instances of PBX systems managed through a centralized portal, PortSIP PBX delivers true multi-tenant functionality. This enables service providers to manage thousands of tenants and dealers on a single, unified infrastructure.
While offering centralized control over all tenants and extensions, PortSIP PBX ensures that each tenant has complete autonomy over their configurations, data, and settings, as if their PBX were hosted on a dedicated instance. Importantly, all tenants are fully isolated, with no visibility into each other’s data or settings, ensuring privacy and security.
Simplicity, flexibility, and scalability
Deploy the communication platform wherever you want—in the cloud, in your data center, or on-premises—all virtually deployed and managed by Docker. The performance-optimized PortSIP PBX takes your business to the next level while protecting your investments with robust, scalable systems that support up to 50,000–100,000 simultaneous online users in a single deployment.
