Troubleshooting
Phone does not power on.
Check the Ethernet cable connection. If using PoE, ensure the switch port supports PoE. If using the AC adapter, verify it is correctly plugged in and the outlet is functional. Try a different outlet or adapter if available.
Cannot connect to the network.
Verify the Ethernet cable is securely connected to both the phone and the network switch/router. Check your network's DHCP settings or ensure a static IP configuration is correct. Reboot your router and the phone.
Poor audio quality or echo.
Ensure Acoustic Shield technology is enabled in settings. Check for physical obstructions near the microphone or speaker. Reduce background noise. Test with a different handset or headset.
Unable to register VoIP account.
Confirm your SIP server address, username, and password are entered correctly. Ensure your network allows SIP traffic and that no firewall is blocking the connection. Contact your VoIP provider for account status.
Display is dim or unreadable.
Adjust the display angle for optimal viewing. Check the LCD brightness settings in the phone's menu. Ensure the backlight is enabled.
