Install and sign in
Download Smileline Desk for macOS or Windows, sign in once, and stay signed in.
Requirements
- macOS 13 (Ventura) or later. On macOS 13, calls ring most reliably while the Smileline Desk window is open.
- Windows 10 or 11.
- A headset is recommended. Calls work through your computer's speakers and microphone, but a headset keeps the caller from hearing their own echo.
Network
Calling from Smileline Desk, or from Smileline in your browser, needs at least 100 kbps per call and under 100 ms round trip. If your practice's firewall limits outgoing traffic, ask whoever manages it to allow:
| Address | Port | Used for |
|---|---|---|
rtc.telnyx.com | 443 (secure WebSocket) | Signing in to calls and ringing |
stun.telnyx.com | 3478 UDP | Finding the shortest route for call audio |
turn.telnyx.com | 3478 UDP and TCP | Call audio when a direct route is blocked |
turn2.telnyx.com | 443 TLS | Call audio through the strictest firewalls |
Install
Get Smileline Desk from your computer's store: the Mac App Store on Mac, or the Microsoft Store on Windows.
Select Get (or Install) and wait for the store to finish.
Launch the app. It appears in your system tray (menu bar on Mac) and opens its window.
When asked Open Smileline Desk when you log in, so you never miss a call?, choose Yes. The app then opens by itself, quietly in the tray, every time you log in — so it rings after a restart. You can change this later: see Open at login.
When the desk isn't in front, a ringing call comes up in a small window with Answer and Decline, so you can take it without opening the app, and the taskbar icon flashes (the Dock icon bounces on Mac) while it rings — see When the desk isn't in front. On Windows, a missed-call or voicemail notification cannot open the app on its own: open Smileline Desk from the tray. On Mac, clicking the app in the Dock brings the window back.
Sign in
Sign in with the same email and password you use in the browser. Your region is handled automatically — the app finds the right Smileline service for your practice on its own.
Smileline Desk is for existing practice accounts. Create an account or organisation, and manage subscription billing, in the web app.
Prefer Continue with Google or Continue with Apple? Choose your practice's service region if prompted.
- In the Mac App Store version, Continue with Apple opens Apple's native sign-in sheet inside Smileline. Directly downloaded Mac versions use the system web authentication session for Apple sign-in.
- On macOS, Continue with Google uses the system's secure web authentication session. macOS may ask whether Smileline can use its sign-in website, then open your default browser or Safari. Complete the prompts to return to Smileline automatically.
- On Windows, social sign-in opens your normal browser and returns you to Smileline when you finish.
Keep Smileline open during sign-in. If you cancel, you can select a provider again. If sign-in cannot start, select Try again or Sign in with email. On macOS, a failed authentication session returns you to the sign-in screen. The desktop flow accepts existing accounts throughout; it does not register a new account through a social provider.
You stay signed in across restarts: quit the app, launch it again, and the queue is back without another sign-in.
The Mac App Store and Microsoft Store deliver updates for store installs. A directly downloaded build prompts when its own update is ready.
