Introducing the Unified Connector App
To simplify deployment and ongoing management, we are consolidating four separate connector applications into a single Unified Connector App.
This approach reduces complexity for both enterprise administrators and end users by eliminating the need to install, configure, and manage multiple Microsoft Teams applications.
Key Benefits
One app, four services: A single installation now supports PBX, CallApp, SMS, and Chat services — no more juggling multiple Teams apps.
Simpler setup: Fewer configuration points and a more streamlined deployment experience.
Consistent user experience: One unified interface across all connector services.
Easier maintenance
Simplified updates and version control
Improved reliability through shared services
Reduced administrative overhead
Clearer support and troubleshooting model
New: AI-powered actions: Starting with system upgrade 2.19.0 on March 17, 2026, the Unified Connector App includes AI support. Users can perform actions like sending SMS messages using plain, everyday language directly from any Microsoft Teams conversation screen — no special commands or navigation required.
Recommendation
The CallApp and Chat services are now available exclusively through the Unified Connector App.
New enterprise deployments are therefore strongly encouraged to use the Unified Connector App for PBX, CallApp and SMS, rather than relying on standalone connector apps.
The end of life date for PBX, CallApp and SMS Connector Apps will be announced soon.
You can configure CallApp users individually or in bulk. This article presents the steps to configure users individually. To configure CallApp users in bulk, check Set Up CallApp User (Bulk)

Part II. Sync Changes to Microsoft
If changes to user/s were made by a Service Provider without Service Provider management consent, the Enterprise Admin must log into the Enterprise Portal and click on Sync Teams Users.
If changes user/s were made by the Enterprise Admin or a Service Provider with management consent, the system automatically syncs the changes. No further action is required.
Check Sync Status
