Desktop Companion Application (DCA) for Dynamics 365 Contact Center

Desktop Companion Application (DCA) for Dynamics 365 Contact Center (A native Windows application designed to provide voice continuity and reliability by operating independently of the web browser).

Real-time User Journey

This journey illustrates how the DCA protects the customer experience during common technical glitches:

1. Shift Start: A Customer Service Representative (CSR) logs into their workstation and ensures the Desktop Companion Application is running in the background.
2. Active Engagement: The CSR accepts an incoming voice call through the Dynamics 365 web workspace. The DCA automatically syncs and mirrors the call status.
3. Technical Disruption: Mid-conversation, the CSR’s web browser freezes or accidentally refreshes.
4. Resilient Continuity: Because the voice path is managed by the DCA (not the browser), the call does not drop. The CSR continues speaking to the customer without interruption.
5. Direct Control: While the browser is reloading, the CSR uses the DCA’s overlay window to mute, unmute, or end the call if necessary.
6. Re-synchronization: Once the browser recovers and the page reloads, the web workspace automatically re-syncs with the DCA, restoring the full customer context and transcript on the CSR’s screen.

Step-by-Step: How to Enable This Feature

To deploy the DCA, administrators and users must follow these steps:

• Step 1: Admin Installation The IT administrator must download and install the Desktop Companion Application (MSI/EXE) onto all service representatives’ Windows machines.
• Step 2: Browser Extension Setup Install the corresponding Dynamics 365 Contact Center browser extension in Microsoft Edge or Google Chrome. This allows the web app and the desktop app to “talk” to each other.
• Step 3: Admin Center Activation In the Contact Center admin center, navigate to Workforce Management or Voice Settings and ensure that the “Desktop Companion” integration is toggled to On.
• Step 4: User Sign-in The CSR signs into the Copilot Service workspace. The DCA will detect the login session and display a “Connected” status at the bottom of its interface.
• Step 5: Device Configuration Inside the DCA Settings tab, the CSR selects their preferred audio devices (headset, microphone) and sets their language preferences to ensure the app is ready to handle calls.
