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 now supports provisioning for Cisco 3PCC phones, giving businesses and service providers a clearer way to connect compatible Cisco multiplatform IP phones to the Vodia PBX. Admins can add supported Cisco devices through Vodia Device Management, pair them with extensions, and configure provisioning settings through the phone’s web interface. This expands Vodia’s supported device ecosystem while helping customers continue using trusted Cisco IP phones within their existing business phone system.
Vodia Hub for Windows brings click to call and desktop call control to Windows, making it easier for users to place, answer, manage, and automate calls from the applications they already use every day. With system wide tel: link handling, inbound call screen pops, queue details, and automation support, Vodia Hub helps connect the Vodia PBX with Outlook, CRMs, browsers, documents, and other Windows tools. Users can keep working without manually copying phone numbers, opening the user portal, or switching between applications just to handle a call.
Desk phones and mobile apps both have a place in modern business communications. IP desk phones remain a strong choice for receptionists, support teams, customer service agents, and employees who handle a high volume of calls from a fixed location. Mobile apps, on the other hand, give remote, hybrid, and field-based users access to their business extension wherever they work. For many organizations, the best answer is not choosing one over the other, but using both through the same PBX environment so every user has the right calling tool for their role.
