A. 1. Check phone connections: Ensure that your landline phone is properly connected to the wall socket and that all cables are secure. 2. Test with another phone: If possible, connect a different phone to the same line to see if the issue persists. This can help determine if the problem is with the phone or the line.

B. 3. Restart your modem: Unplug your modem for 30 seconds and plug it back in. This can help reset the connection and resolve issues.
