VoIP Domain is a modern web-based administration interface for Asterisk‑based PBX systems, designed to simplify VoIP telephony management for small, medium and large businesses, as well as service providers. It provides multi-tenant, centralized multi‑server control, device provisioning, least cost route, billing, routing, and a modular architecture via a RESTful API.

VoIP Domain was created in 2008 by Ernani Azevedo and improved over the time to create a complete enterprise class VoIP administration system. The main purpose was to create a powerful and complete tool that could be managed by non-technical users, allowing companies to manage their telephony system with lower technical terms, keeping all the complexity and automation to be done by the software.

Overview

VoIP Domain allows administrators to manage multiple Asterisk servers through a single intuitive interface. Its design supports users with minimal VoIP expertise, offering features such as:

Multi‑tenant architecture to serve multiple customers from a single installation
Automatic phone provisioning supporting various manufacturers and models
Least‑Cost Routing (LCR) for optimized call paths
Per‑call billing and rating built-in
Centralized server management, even for offline servers
Workflow-configurable IVR menus
Automatic dial‑plan generation
RESTful API (Swagger‑documented, OAS 3.0), enabling integrations and extensions
100% modular architecture with plugin support and multi‑language (English, Brazilian Portuguese)

History

VoIP Domain’s public development began with GitHub releases: alpha version v0.0.1 was released in May 2018, followed by v0.0.2 in October 2018 with significant feature additions. After several years of development and rewrites, version 0.1 was released in April 2025, marking the first pre‑release. A major system refactor adding multi‑tenant support and performance enhancements was released as version 0.2 on July 21, 2025.

VoIP Domain was conceived by VoIP specialist Ernani José Camargo Azevedo to bring transparency and simplicity to telephony management for smaller organizations and providers.

Features

VoIP Domain supports functionality expected of commercial PBX systems:

Call routing (automatic dial plans, intelligent routing logic)
Least‑Cost Routing (LCR) to minimize call costs
Call billing and call detail records (CDRs)
IVR creation and call menu workflows
Phone provisioning automation
Support for multiple Asterisk server clusters
System-wide multi-language support – actually English and Brazilian Portuguese
RESTful API access for automation and integration
Modular plugin architecture, extensible by custom components

Architecture & Compatibility

VoIP Domain is built in PHP, with a fully modular codebase. It interfaces directly with Asterisk servers, even when they are offline. Configuration deployment is handled through the web UI, eliminating the need to SSH into servers after initial setup. The platform provides automatic provisioning, dial plans, billing, and call routing configured via a unified interface.

Use Cases

Small to big businesses that require user‑friendly control over VoIP without in‑depth technical expertise
VoIP service providers leveraging multi‑tenant architecture to serve multiple clients from one instance
Organizations needing centralized oversight of multiple Asterisk servers, including remote or offline systems

License and Status

VoIP Domain is distributed under the GPLv3 license. As of July 21, 2025, the project is in pre‑release (v0.2) status, with further stable releases forthcoming.
