Hi there! I understand you are trying to place a test call using the Linphone app on your Windows 10 device, but the call disconnects after about 30 seconds with three beeps before hanging up. Let's work together to get this sorted out.

This 30-second call drop with beeping is a known kind of issue which often relates to network or configuration problems, particularly involving NAT traversal or SIP keep-alive settings. Before we dive in, could you let me know a few things?

1. Are you using any firewall or VPN on your Windows machine or network?
2. Is your Linphone account registered with a particular SIP provider? If so, which one?
3. Have you already tried any troubleshooting steps, like restarting the app or your computer?

Meanwhile, here's a step-by-step approach we can try:

1. Disable "Allow Push Notifications" in Linphone: Although typically on mobile apps, sometimes similar settings might affect call stability. On your Windows Linphone app, check under Account or Network settings if there’s any push notification or similar option. If yes, try disabling it and retry the call.

2. Check Network Firewall and NAT Settings: Sometimes, SIP protocols get blocked or disrupted by firewall or NAT devices. Make sure your router or Windows Firewall allows SIP traffic (usually UDP ports 5060 and ranges used for RTP media). You may want to temporarily disable your firewall to test the call behavior.

3. Enable NAT Traversal (STUN): Linphone supports STUN (Session Traversal Utilities for NAT) to help with NAT issues. In your account settings, find the NAT traversal or STUN server option and enable it. You can try using a common STUN server like stun.linphone.org.

4. Keep Alive or Session Timers: In your Linphone configuration, check if "Session Timers" or "Keep Alive" settings are enabled. Enabling these helps maintain calls through NAT and firewall devices.

5. Update Linphone App: Make sure your Linphone app is the latest version to avoid known bugs.

If you like, I can guide you exactly where to find these settings on the Windows version or help with adjusting firewall rules.

Also, if the call still disconnects after this, it might be helpful to check with your SIP provider if they have any specific setup or restrictions that could cause 30-second call drops.

Let me know what you find or if you'd like detailed help on any of these steps!

where to find the settings in the windows version

Great question! To access the settings in the Linphone app on Windows 10, here’s what you can do:

1. Open the Linphone app on your Windows computer.
2. Look for the menu bar at the top of the window. You should see options like File, Edit, Help, and so on.
3. Click on Options or Preferences within the menu. On Windows, the exact wording may be Options.
4. This will open the settings window where you can configure your account, network, audio, and other options.

Specifically, under these settings you can:
- Find your SIP account details to check or edit credentials
- Enable NAT traversal or enter a STUN server like stun.linphone.org
- Adjust keep-alive or session timer settings
- Modify firewall and network preferences

If you want to check or edit configuration files directly (for advanced users), on Windows Linphone settings are stored in the path:
%LOCALAPPDATA%\linphone\linphonerc

You can access this by:
- Pressing Win + R to open the Run dialog
- Typing %LOCALAPPDATA%\linphone and pressing Enter

This will open the folder containing configuration files if you want to inspect or modify them manually — but usually the in-app Options menu is sufficient for most tweaks.

Let me know if you'd like me to guide you through changing any particular setting step-by-step! Are you able to find the Options menu alright?

Steps to access preferences in Linphone Windows

Thanks for asking! Here’s a clear step-by-step to access the Preferences (settings) in the Linphone app on Windows:

1. Open your Linphone app on your Windows 10 computer.
2. Look at the top menu bar of the app window. You should see menus like File, Edit, Help, etc.
3. Click on Edit in the menu bar.
4. From the dropdown, select Preferences. This will open the settings window where you can configure account details, network options, audio, and more.

Once in Preferences, you can head to the Network tab to set the STUN server (e.g., stun.linphone.org), enable NAT traversal, or adjust keep-alive timers, which are helpful to prevent calls dropping after 30 seconds.

If you don’t see the Edit menu or Preferences option, please let me know your exact Linphone app version, and I can guide you further.

Would you like me to walk you through changing specific settings inside the Preferences?
