If you're experiencing poor call quality when using the Line2 app, the issue is usually related to your internet connection, device settings, permissions, or audio hardware.
This guide will help you identify and resolve the most common causes of:
- Dropped calls
- One-way audio (you can hear the caller, but they can't hear you, or vice versa)
- Choppy or robotic audio
- Echo during calls
- Delayed audio
- Calls not ringing
- Poor speaker or microphone quality
Because Line2 uses an internet connection (VoIP) to place and receive calls, call quality depends on both your device and network performance.
Check Your Internet Connection
Most call quality issues are caused by unstable internet connectivity.
Recommended Actions
- Connect to a strong Wi-Fi network whenever possible.
- Move closer to your wireless router.
- If available, use a wired internet connection on desktop devices.
- Temporarily disable VPN software and test again.
- Pause large downloads, streaming services, or cloud backups during calls.
Signs of a Network Issue
- Calls sound robotic or distorted.
- Audio cuts in and out.
- Calls disconnect unexpectedly.
- Significant delays between speakers.
If possible, switch between Wi-Fi and cellular data to determine whether the issue is network-related.
