Hey ​@JohnGBerg0816,

Here are some troubleshooting steps for resolving the issue of not getting a dial tone on your Cisco SPA 525G:

• Check the Physical Connections:

  • Ensure that the Ethernet cable is securely connected to the correct port on the phone and to the network switch or router.
  • Verify that the power adapter is properly plugged into the phone and a functioning power outlet.

• Confirm the Phone is Powered On:

  • Make sure the phone's display is active. If not, check the power adapter or try a different power source.

• Verify the Handset and Headset Connections:

  • Ensure the handset is properly connected to the phone’s handset port.
  • If using a headset, confirm it is securely plugged into the headset jack.

• Test with the Speakerphone:

  • Press the Speaker button and see if you can hear a dial tone. If a dial tone is present on the speaker but not the handset or headset, the issue may lie with the handset or headset itself.

• Restart the Phone:

  • Power cycle the phone by unplugging it from the power source, waiting 10 seconds, and plugging it back in. Allow the phone to reboot fully.

• Check Network Connectivity:

  • Confirm that the phone is properly connected to the network and has an IP address:
    • Press Setup > Network Status to view the phone’s IP address.
  • If no IP address is displayed, there may be an issue with your network.

• Verify SIP Registration:

  • Ensure the phone is registered to the SIP server:
    • Press Setup > Status > Line Status to check the registration status.
    • If the status shows "Not Registered," contact your IT or service provider to verify your SIP credentials.

• Update Firmware (If Necessary):

  • Check if the phone’s firmware is up-to-date. Outdated firmware can cause functionality issues.
    • Contact your IT admin or service provider for guidance on updating the firmware.

• Reset to Factory Settings (if applicable):

  • As a last resort, reset the phone to its factory default settings:
    • Press Setup > Factory Reset (may require admin credentials).
  • Note: Resetting will erase all configurations, so reconfiguration will be required afterward.
