FusionPBX

FusionPBX is a full-featured, domain-based multi-tenant PBX and voice switch built around FreeSWITCH. It provides a web-based interface to manage telephony features for businesses, service providers, and multi-customer environments.

Key Features

• Domain-based multi-tenancy for hosting multiple independent PBX tenants
• Extension and user management with typical PBX calling features
• IVR, ring groups, call parking, and call routing via dialplan tools
• Call queues / ACD and call center-oriented applications
• Voicemail features including voicemail-to-email support
• Device provisioning with troubleshooting logs for provisioning requests
• Call detail records (CDR) and call recordings management
• High availability and redundancy options for more resilient deployments

Use Cases

• Hosting a multi-tenant PBX platform for customers or departments
• Building a VoIP business phone system with IVR, voicemail, and queues
• Running a FreeSWITCH-based softswitch with web-managed configuration

Limitations and Considerations

• Requires deploying and operating FreeSWITCH alongside the FusionPBX web application
• Some advanced features (for example, certain reporting modules and the REST API) may depend on membership or add-on applications

FusionPBX is well-suited for organizations that want a FreeSWITCH-based telephony stack with a comprehensive administrative UI and multi-tenant capabilities. It scales from single-instance PBX deployments to carrier-oriented environments when designed with redundancy in mind.
