6. Troubleshooting
If you encounter issues with your YEASTAR P520, consider the following troubleshooting steps:
- No Power:
- Ensure the power cable is securely connected to both the unit and a working power outlet.
- Check if the power outlet is functional by plugging in another device.
- No Network Connectivity:
- Verify that the Ethernet cable is properly connected to the P520's LAN port and your router/switch.
- Check the status of your router/switch and internet connection.
- Confirm that the network settings on the P520 are correct via the web management interface.
- Cannot Make/Receive Calls:
- Ensure your IP phones or softclients are registered with the P520.
- Check your internet connection and firewall settings, as they can affect VoIP traffic.
- Verify that the extensions are correctly configured and assigned.
- Poor Call Quality:
- Check your network bandwidth and ensure there is sufficient capacity for VoIP calls.
- Reduce network congestion by limiting other high-bandwidth activities.
