Hi there! I understand your headset disconnects when you make phone calls through the Lead Connector app. Let's try to figure this out together.

A couple of quick questions to narrow down the issue:
- Is your headset connected via Bluetooth or wired?
- Does it disconnect immediately when the call starts, or after a few seconds?
- Have you noticed if this happens only with Lead Connector calls or with other apps/calls as well?
- What brand and model is your headset?

Meanwhile, here’s a step-by-step approach to try:

1. Check Bluetooth or Wired Connection
- If Bluetooth: Ensure the headset battery is fully charged. Sometimes low battery can cause disconnects during active calls.
- Make sure the headset is within close range of your PC or device so the signal stays strong.
- Try unpairing and re-pairing the headset in your Windows Bluetooth settings.
- Restart Bluetooth on your PC by turning it off and on again.

2. Restart the App and Device
- Fully close the Lead Connector app and restart it.
- Restart your computer as sometimes this resets connection issues.

3. Default Audio Device Settings
- Right-click the speaker icon in the Windows system tray > Sounds > Playback and Recording tabs. Make sure your headset is set as the Default Communication Device (not just default playback).
- Sometimes apps switch audio devices when calls start, so this step helps ensure the headset stays in control.

4. Update Drivers and App
- Check that your Bluetooth and audio drivers are up to date (Device Manager → Bluetooth and Sound, video and game controllers → Update driver).
- Make sure the Lead Connector app is updated to the latest version.

5. Disable Power Saving for Bluetooth
- Go to Device Manager → Bluetooth → right-click your Bluetooth adapter → Properties → Power Management tab.
- Uncheck “Allow the computer to turn off this device to save power.”

If these steps don’t work, there may be app-specific compatibility issues or headset firmware problems. You might also test with a different headset if available, to isolate whether it's app or hardware related.

Could you please try these and let me know what you observe? If the problem continues, I’m happy to dive deeper!
