FusionPBX

Multi-tenant FusionPBX on FreeSWITCH for hosted PBX, domains, and operator-friendly admin UIs.

FusionPBX gives operators a multi-tenant management layer on FreeSWITCH. We deploy and configure FusionPBX for hosted or enterprise PBX use—domains, extensions, gateways, dialplans, and permissions—so your team can provision customers or departments without editing FreeSWITCH XML by hand for every change.

FAQ

No. Use FusionPBX when you want a multi-tenant UI and provisioning model. Pure FreeSWITCH is fine for application-driven platforms.
