Users and admins can navigate with ease, making changes without confusion. Tailwind CSS is used for stylish, mobile-friendly design

- FS PBX supports robust deployments with master-to-master (bi-directional) PostgreSQL database replication and file synchronization between servers. This ensures zero downtime, automatic failover, and seamless continuity even if one node goes offline. Perfect for VoIP providers who require maximum reliability and business continuity.
Everything you need
Built for VoIP Providers.
White Label Ready
Designed with simplicity in mind
FS PBX is designed with VoIP service providers in mind, particularly those needing a white-label PBX solution for their customers. It supports full multi-tenancy, allowing you to host multiple client PBX instances on a single system – each client (tenant) is completely separated in the database and dial-plan. Unlike FusionPBX which requires separate domain URLs or awkward username formats for each tenant, FS PBX uses a unified login portal for all tenants. Users simply log in with their email, and FS PBX intelligently routes them to their correct tenant space
Reseller access
For resellers, FS PBX provides a multi-site admin console: admins can effortlessly switch between different customer domains through a redesigned domain selector. You can grant resellers access to manage their client accounts all from one master dashboard – no re-login to different URLs required. This architecture makes maintenance easier for providers and gives end-users a smoother experience (for example, password resets are simpler since users just know their email)
FS PBX vs FusionPBX – Why Upgrade?
FS PBX began as a FusionPBX fork, but it has rapidly evolved into a superior platform. Here are some key reasons why FS PBX outperforms FusionPBX:
In summary, if you’re currently using FusionPBX or evaluating open-source PBX systems, FS PBX offers a compelling upgrade: you keep the reliability of FreeSWITCH and the familiarity of FusionPBX’s features, but gain a faster, easier, and more powerful system. As one industry expert noted, “Everyone needs to take a careful look at this platform... The interface is downright magical.”
