UCC Desktop App (Windows)

The desktop app is the same Unified Contact Center client as the Android app, built for Windows. It talks to the same API as the applet, so the three stay in step.

Everything in the mobile guide applies here — signing in, the chat list, group topics, attachments, voice notes, offline reading and the outbound queue. This page covers only what is different on a desktop.

Installing it

The app is distributed as a Windows installer (.msi) built from the repository; there is no download page yet. The installer registers the app as BLG UCC and installs it to C:\Program Files\BLG UCC\BLG UCC.exe.

To build the installer yourself you need JDK 21 (a full JDK — the Android Studio runtime will not do, as it has no jpackage), then:

./gradlew :composeApp:packageMsi

The result lands in composeApp/build/compose/binaries/main/msi/. macOS (.dmg) and Linux (.deb) targets are configured but are built on those platforms.

To run it without installing, from the repository:

./gradlew :composeApp:run

The window

The app opens at 1100 × 820 and can be resized.

Above roughly 720 points wide you get two panes: the conversation list on the left, the open chat on the right. Below that — a narrow or half-screen window — it behaves like the phone, showing one screen at a time and sliding between them.

The divider between the panes is draggable. Drag it to give the list or the conversation more room; the list will not go below 280 points, and always leaves at least 400 for the chat. The width resets when you restart the app.

The ☰ menu holds the same destinations as on the phone: Conversations, Notifications, Tasks, Profile, the Inbound / Outbound Leads switch, the dark-mode toggle and Sign out.

Typing and sending

Enter sends the message. Shift+Enter or Ctrl+Enter starts a new line instead. The send button works too.

Attachments open a normal Windows file chooser, from the 📎 button: photo, video or document. Voice notes record from your default input device and send as WAV files.

Notifications

With no Android notification shade to use, the desktop app puts an icon in the system tray and shows a tray notification when a message arrives, with the same rules as the phone: nothing for a conversation you already have open, and the sender named in a group.

If your Windows account has notifications switched off for background apps, or the system tray is unavailable, messages still arrive in the app — only the pop-up is lost.

What it keeps on this machine

Worth knowing for a shared or managed computer:

What	Where
Saved conversations, messages and queued replies	`%LOCALAPPDATA%\BLG UCC\ucc_cache.db`
Your signed-in session	Windows registry, under the Java Preferences tree for `org/company/app`

Signing out deletes both. The database is not encrypted, so on a shared machine treat signing out as part of finishing a shift. Closing the window alone leaves everything in place, which is what makes the next launch instant.

How it differs from the phone

No background delivery. The Android app runs a service that keeps receiving messages with the app in the background; on desktop, notifications arrive only while the app is open.
The window remembers nothing between runs — not its size, nor the divider position.
The same sample-data limits apply: Outbound Leads, Notifications and Tasks are not wired to the server. Only Conversations is.
