Ozonetel IVR System vs Wazo Platform

Ozonetel IVR System is a cloud service for automated attendants, caller self-service, and smart call routing. Its visual builder lets users create and change IVR flows without code. Callers can navigate multi-level menus, use after-hours routing or callbacks, and reach skills-based routing. Speech recognition and natural language processing allow spoken interaction instead of keypad input. The system can run outbound campaigns for satisfaction surveys, feedback collection, and notifications about offers or dues. Listed CRM and CTI integrations include Salesforce, Zoho, Zendesk, Freshdesk, and HubSpot. An open API library and the option to use an existing SIP trunk are available. Ozonetel says its self-service tools can triple call-handling capacity and enable four-times-faster response times; it also says the platform handles 2.5 billion calls annually. Support includes 24 x 7 live phone assistance, onboarding, and training. Ozonetel states that it is HIPAA compliant and holds ISO 27001:2013 and ISO 20000-1:2018 certifications. Pricing is on request, and a 7-day trial is promoted. The advertised 99.99% uptime SLA varies by region.

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.
