3.2. Initial Configuration

The SPA122 typically requires configuration through its web-based interface. Consult your VoIP service provider for specific settings.

1. Access Web Interface: Open a web browser on a computer connected to the same network as the SPA122. Enter the device's IP address (usually found in the Quick Start Guide or by checking your router's connected devices list) into the browser's address bar.
2. Login: Enter the default username and password (commonly 'admin' for both, or as provided by your service provider).
3. Configure SIP Settings: Navigate to the voice settings and enter the SIP server address, user ID, password, and other parameters provided by your VoIP service provider.
4. Save and Reboot: Save your changes and reboot the device for the settings to take effect.

4. Operating the Device

Once configured, the Cisco SPA122 operates largely transparently, enabling your analog phones to function with your VoIP service.

4.1. Making Calls

Lift the handset of your connected analog phone. You should hear a dial tone. Dial the desired phone number as you normally would. The SPA122 will convert the analog signals to digital VoIP packets and route them through your internet connection.

4.2. Receiving Calls

When an incoming call arrives, your connected analog phone will ring. Answer the call by lifting the handset.

4.3. Using Fax Machines

Connect your fax machine to one of the Phone ports. Ensure your VoIP service provider supports T.38 faxing for reliable fax transmission over IP.

5. Maintenance

Regular maintenance helps ensure optimal performance and longevity of your SPA122.

• Firmware Updates: Periodically check the Cisco support website for firmware updates. Firmware updates can provide new features, security enhancements, and bug fixes. Follow Cisco's instructions carefully when performing updates.
• Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or aerosols.
• Ventilation: Ensure the device is placed in a well-ventilated area to prevent overheating. Do not block ventilation openings.
• Power Cycle: If the device experiences minor issues, a simple power cycle (unplugging the power adapter for 10 seconds and plugging it back in) can often resolve them.

6. Troubleshooting

This section addresses common issues you might encounter with the Cisco SPA122.

6.1. No Dial Tone

• Check Power: Ensure the power adapter is securely connected and the power LED on the SPA122 is illuminated.
• Check Phone Connection: Verify that the analog phone is correctly plugged into the Phone 1 or Phone 2 port.
• Check Network Connection: Ensure the Ethernet cable is securely connected to the Internet/Ethernet port and your network is active.
• Verify SIP Registration: Access the SPA122's web interface and check the status of your SIP lines. If they are not registered, re-verify your SIP configuration settings with your VoIP service provider.
• Reboot: Power cycle the SPA122 and your network equipment (modem/router).

6.2. Cannot Make or Receive Calls

• Check Dial Tone: Confirm you have a dial tone. If not, refer to the 'No Dial Tone' section.
• Verify SIP Configuration: Double-check all SIP account details (username, password, server address) in the web interface. Even a small typo can prevent service.
• Internet Connectivity: Ensure your internet connection is active and stable. Test by browsing a website on a connected computer.
• Firewall Issues: Your network firewall might be blocking VoIP traffic. Consult your network administrator or VoIP provider for required port forwarding or firewall exceptions.

6.3. Poor Call Quality (Echo, Jitter, Dropped Calls)

• Internet Bandwidth: Ensure you have sufficient internet bandwidth, especially during peak usage. VoIP requires stable bandwidth.
• Network Congestion: Other devices on your network might be consuming too much bandwidth. Consider implementing Quality of Service (QoS) settings on your router to prioritize VoIP traffic.
• Cables: Ensure all Ethernet and phone cables are in good condition and securely connected.
• VoIP Provider: Contact your VoIP service provider to check for any service-side issues or recommended settings for your specific network environment.
