In their own words
Wazo Platform
Wazo Platform is a free, open-source stack of telecom microservices for building programmable voice, video, messaging, and presence services. Its capabilities include audio and video calls, chat, call centers, conferences, voicemail, custom call routing, and an auto attendant. Interfaces include WebRTC, REST APIs, WebSockets, and Webhooks, described as mobile- and web-friendly. The microservices are developed in Python, and APIs are described through OpenAPI specifications. Asterisk, RTPEngine, and Kamailio make up the telecom engine; RabbitMQ, NGINX, and PostgreSQL support the technical core. Wazo can be deployed on bare metal, virtual machines, or containers. The documented all-in-one installation uses Debian 12 Bookworm and Ansible; minimums for a small production installation of about 50 users are 2 CPUs, 4 GiB RAM, and 50 GiB storage. The GPL-3 license allows free use, including commercial use. APIs can integrate billing and services such as speech-to-text, AI, or sentiment analysis. Community support is available through Mattermost, a forum, and JIRA.
