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.

Vodia Wallboards gives supervisors, contact centers, service providers, and operations teams a self-hosted, real-time view of Vodia call queue activity. Monitor waiting, ringing, and active calls; agent availability; service levels; abandoned calls; and queue trends across one or more Vodia PBX systems. Start with a ready-made layout or build a custom wallboard using queue filters, live widgets, AI summaries, and alerts. Display the information your teams need in a browser, on an operations dashboard, or on a dedicated TV screen.
AI-powered calling gives businesses new ways to manage conversations, improve availability, and respond to callers more efficiently. It also introduces important questions about transparency, consent, privacy, data handling, and accountability. Organizations need clearly defined boundaries for what a Voice Agent may answer, which systems it can access, and when identity verification or human assistance is required. A thoughtful deployment balances automation with appropriate safeguards, helping businesses use conversational AI confidently while protecting callers and maintaining trust.
