I'd like to share OpenWebPBX, an open-source, self-hosted PBX project built around FreeSWITCH and FusionPBX technologies.

For developers, system administrators, and VoIP enthusiasts interested in managing their own communications infrastructure, this project is worth exploring.

What Is OpenWebPBX?

OpenWebPBX is a multi-tenant business phone system with a web-based administration interface inspired by the Windows 11 desktop experience.

The project aims to simplify everyday PBX administration while keeping the system self-hosted and its source code publicly accessible.

It provides tools for managing business calling workflows, extensions, routing, and other communications features.

Key Features

OpenWebPBX presents several capabilities:

• Multi-tenant management: Manage separate organizations and their phone configurations.

• SIP trunks: Configure providers and business calling connections.

• Call routing: Set up office hours, departments, and incoming call destinations.

• Call queues: Organize incoming calls and agent availability.

• Receptionist tools: Support call handling, transfers, and related workflows.

• Backups and restore: Tools for backup and recovery.

• Android companion app: An OpenWebPBX Free Phone application for Android.

• Web-based administration: Manage PBX settings through a desktop-style interface.

• Meetings: Audio and video conferencing functionality.

Feature availability and compatibility should be checked against the project's documentation and current release.

Self-Hosting and Deployment

One of the project's main attractions is the ability to host the PBX on infrastructure you control.

The project website lists a Debian 13 installer for version 1.0.16, along with an Android companion application.

Before deploying OpenWebPBX for production calls, it's important to review the installation documentation and test your SIP provider, networking environment, and phone devices.

Some areas still require additional real-world verification, including physical phone behavior, carrier cutovers, certain network conditions, and broader device compatibility.

Is OpenWebPBX Free?

According to the project website, OpenWebPBX does not charge an OpenWeb software license fee.

However, hosting infrastructure, SIP carrier services, and optional third-party services may have separate costs.

Users should also review the repository's licensing information and the licenses of included components.

Feedback Welcome

I'd be interested to hear from developers, system administrators, and VoIP enthusiasts:

• What features matter most to you in a self-hosted PBX?

• Which installation or configuration steps are usually the most challenging?

• What improvements would you like to see in open-source business phone systems?

Feel free to explore the repository and share constructive feedback.
