Check internet connection: Since 2ndLine utilizes VoIP technology, a weak or unstable internet connection can cause audio issues. Check the WiFi signal or ensuring sufficient mobile data allowance.

Restart the app and device: Sometimes, a simple app restart or device reboot can resolve temporary glitches.

Clean the microphone: Dust or debris around the microphone might hinder sound clarity. Gently clean the microphone opening with a soft brush.

Verify device settings: Check if other apps might be using the microphone exclusively, like voice recorder or music apps. 

If the other person can't hear you during a call, here are some steps to troubleshoot:

Microphone Permissions:

  • Ensure you've granted microphone access to the 2ndLine app. Follow these steps for your device:

          iOS:  Settings > Privacy & Security > Microphone > Toggle on for 2ndLine.

Remember :

  • If you're still facing issues, reach out to 2ndLine support for further assistance.
