Keycloak OpenID Connect Integration for the Vodia PBX
Published on:
September 12, 2025
Vodia’s PBX now integrates with Keycloak OpenID Connect, providing secure single sign-on for users so they can access all connected applications without repeated authentication. Logging out from one application automatically logs the user out of all connected systems, simplifying user management and improving security. Keycloak, a Cloud Native Computing Foundation project, supports standard protocols including OpenID Connect, OAuth 2.0, and SAML, offering enterprise-grade identity and access management. To ensure proper integration, Keycloak user emails must match the corresponding PBX extension emails. Complete guidance is available in the Vodia Keycloak integration guide.
Vodia’s PBX now supports Keycloak OpenID Connect, enabling secure single sign-on for your users. Once a user logs in through Keycloak, they can access all connected applications without repeated authentication. Logging out from one application also logs the user out from all connected systems, simplifying user management and improving security.
What Is Keycloak?
Keycloak is a Cloud Native Computing Foundation (CNCF) incubation project. CNCF is the open source, vendor-neutral hub of cloud native computing, hosting projects such as Kubernetes and Prometheus that make cloud native universal and sustainable. A number of global organizations have recently shared their Keycloak case studies, including the Austrian Business Service Portal, Hitachi, and OpenTalk.
How Keycloak Works
Vodia users can now authenticate with Keycloak, rather than with individual applications, so these apps don’t require authenticating users, login forms, and storing users. Once a user logs in to Keycloak, it isn’t necessary to log in again to use another application.
This also applies to logging out, as Keycloak enables single-sign out (SSO): once a user logs out of an application, this user is automatically logged out of all applications using Keycloak. Keycloak is based on standard protocols and provides support for OpenID Connect, OAuth 2.0, and SAML.
The Integration of the Vodia Phone System with Keycloak
The integration of the Vodia phone system with Keycloak provides enterprise-grade identity and access management.
This allows for secure Single Sign-On (SSO), but Keycloak user emails must match the corresponding extension email addresses on the PBX.
The Vodia phone system is the best choice for enterprises and SMBs looking to build feature-rich, robust, scalable, and secure business communication ecosystems that integrate with the world’s best business communications software - our integration with Keycloak OpenID Connect is just the latest in a series of integrations we’ve completed with some of the world’s best business communications software, including ActiveCampaign, Freshdesk, HighLevel, Microsoft Dynamics 365, monday.com, and Odoo Cloud, among others.

Vodia Sales Engineer Eric Altman will attend HITEC North America 2026 in San Antonio, Texas, where he will discuss V70, the latest version of the Vodia PBX, and its applications for the hospitality industry. Vodia will showcase its AI-driven communications capabilities, hospitality-focused PBX features, integrations with leading property management systems and hotel phones, and solutions designed to help hotels improve guest experiences, streamline operations, and support modern communication requirements.
Modern business communication rarely happens within a single office or PBX environment. With V70 of the Vodia PBX, organizations and service providers can now share presence information between tenants and across separate PBX systems. External Presence Sharing extends BLF visibility beyond a single deployment, helping distributed teams maintain awareness of user availability across locations, departments, and communication environments while supporting more connected and flexible business communications.
V70.2 introduces more flexible licensing for multi-tenant PBX deployments by allowing service providers to assign prepaid licenses directly to tenants within a postpaid environment. Once assigned, the tenant uses the prepaid license independently, and the underlying postpaid license no longer counts that tenant. This gives MSPs and hosted PBX providers more flexibility in how they structure customer licensing while continuing to operate tenants on shared infrastructure, reducing operating costs and simplifying large-scale multi-tenant deployments.
