The Desktop companion application for Dynamics 365 Contact Center is a native Windows client that keeps agent voice calls alive when the browser workspace freezes, reloads, or crashes, so representatives stay connected.
The Desktop companion application for Dynamics 365 Contact Center is a lightweight Windows client that runs alongside the Copilot Service workspace browser app and carries the voice call leg. Representatives sign in through the web application as usual, and when a call arrives it appears in both places at once. If the browser tab freezes, reloads, or crashes mid-conversation, the call keeps running on the desktop, where an agent can mute, unmute, end the call, or move between an active call and one on hold. Connectivity status and audio device health stay visible, so it is obvious when the desktop client is handling the conversation and when something needs attention.
Rollout follows the pattern many Microsoft desktop utilities use: an administrator installs the client on representative machines, adds the matching Chrome or Edge extension, and keeps updates under central control rather than leaving them to individual users. The Desktop companion application for Dynamics 365 Contact Center depends on that pairing, because the extension is what surfaces the launch control inside the workspace while the desktop client holds the call itself. Teams already familiar with tools such as Microsoft Advertising Editor will recognize the model — install once, configure per user, and leave the day-to-day experience untouched. Diagnostic data collection can be reviewed centrally, and representatives can generate support files from the app menu when support needs a trace.
Dropped calls are expensive in more ways than one. Every reconnect forces a customer to repeat context, stretches average handling time, and undermines the confidence a representative needs to resolve an issue cleanly. The Desktop companion application for Dynamics 365 Contact Center removes the most common source of that disruption: the browser itself. When a tab stalls or reloads, the conversation continues, recording and transcription carry on as configured, and the representative stays in control of a call the customer never noticed was at risk. The practical gains compound across a queue. Fewer failed connections mean higher call completion and shorter speed to answer, and agents spend their attention on the customer rather than on recovering from a technical fault. Device controls matter daily too: representatives pick their microphone and speaker, run a test call before going live, and watch connectivity status so headset or Bluetooth problems surface early instead of mid-conversation. Over a full shift, that reliability is what keeps service quality steady.
Key capabilities and highlights.
When the Copilot Service workspace tab freezes, reloads, or crashes, the Desktop companion application for Dynamics 365 Contact Center keeps the voice connection running in its own process. Customers never hear a dropped line, and representatives keep the conversation instead of asking a caller to repeat details after a reconnect.
Mute, unmute, end a call, and switch between an active call and one on hold straight from the client window, no matter how the browser is behaving. The Desktop companion application for Dynamics 365 Contact Center also runs minimized in the background, so an agent can keep the controls close without a second window competing for screen space.
The companion extension for Chrome and Edge places a launch control inside the workspace, so the Desktop companion application for Dynamics 365 Contact Center opens the moment it is needed instead of being hunted for on the Windows toolbar. Pinning the extension to the toolbar keeps that shortcut one click away for the whole shift.
The app displays which environment a representative is signed in to along with a live connectivity indicator. When the Desktop companion application for Dynamics 365 Contact Center takes over a call, a message in the web communication panel confirms the handoff, so agents and supervisors can see at a glance that the desktop client, not the browser, is holding the line.
Choose the audio input and output device inside the settings pane and keep that preference between sessions. Representatives who dock and undock laptops, swap headsets, or move between USB audio devices can let the Desktop companion application for Dynamics 365 Contact Center handle the device switch rather than fighting browser audio settings.
Run a test call from the settings pane to confirm the microphone and speaker are working before going live. A representative using the Desktop companion application for Dynamics 365 Contact Center can catch a faulty headset, an unplugged microphone, or a muted input before a customer is on the line rather than after the call has already started badly.
Calls handled by the desktop client continue to be recorded and transcribed whenever those capabilities are enabled for the web version, so quality reviews and compliance records stay complete. The Desktop companion application for Dynamics 365 Contact Center keeps that continuity during a browser disruption, which matters most in the moments an agent would otherwise lose the call entirely.
Administrators can prevent representatives from updating the client themselves, keeping versions consistent across an entire floor, and can govern how diagnostic data is collected. The Desktop companion application for Dynamics 365 Contact Center also supports generating support files from the app menu, giving Microsoft support the detail it needs to trace a reported problem.

Common questions about Desktop companion application for Dynamics 365 Contact Center.
It runs the voice call leg in a native Windows process rather than in the browser. The Desktop companion application for Dynamics 365 Contact Center keeps a conversation going if the Copilot Service workspace page refreshes, freezes, or crashes, so representatives and customers stay connected when the web application is struggling.
Yes. Representatives sign in to the Copilot Service workspace as usual and accept calls there, and the Desktop companion application for Dynamics 365 Contact Center mirrors the call in its own window. It works as a backup path rather than a replacement, so the day-to-day agent workflow does not change until the browser needs rescuing.
Microsoft provides companion extensions for Chrome and Edge. The extension adds a launch control inside the browser so representatives can open the client directly from the workspace. After enabling the extension, the browser has to be restarted for the change to take effect.
Yes. The settings pane lists the available microphones and speakers so an agent can select the device to use, and the app holds the audio connection steady even when a headset or Bluetooth link is unreliable. Running a test call after a change confirms everything is working.
The client displays the active call next to a connectivity status indicator. A message also appears in the communication panel of the web application confirming the call is being handled by the desktop companion application, so the handoff is visible to the agent rather than happening silently.
No. Recording and transcription continue for calls handled by the desktop client as long as those capabilities are enabled for the web version, so compliance and quality records remain complete even when the browser misbehaves.
Administrators can restrict representatives from updating the application themselves, which keeps versions consistent across the floor, and can review the diagnostic data the client reports. The app also supports generating support files that can be sent to Microsoft support during troubleshooting.
Microsoft recommends using the desktop client with one environment at a time. To move to another environment, close the current one first, then sign in to the other environment before taking calls again.
The Desktop companion application for Dynamics 365 Contact Center is a native Windows client that keeps agent voice calls alive when the browser workspace freezes, reloads, or crashes, so representatives stay connected.
