FAST Discovery:

  3. Ask if the Phone is plugged into the computer.
  4. Ask if the CAT5 Cable is plugged into the LAN port on the phone.

This error typically indicates a local network connectivity problem or some other issue preventing the phone from registering with 8×8 service. This can include:

  1. Faulty port(s) or cabling.
  2. The phone being unable to register with the 8×8 SIP Server (no service), possibly due to firewall or not being located on the proper subnet.
  3. Polycom phones being generally sensitive to SPI. Combo (modem/router) devices are notorious for having SPI enabled by default. Some don’t have the ability to disable SPI.
  4. DNS issues.
  5. Other problematic network setup issues like the DHCP not working.

Reset the local configuration file on the phone

  1. Press “Menu” button on the phone.
  2. Select option 3, “Settings”
  3. Select option 2, “Advanced”
  4. Enter password “456”
  5. Press “Enter”
  6. Select option 1, “Admin Settings”
  7. Select option 5, “Reset to Defaults…”
  8. Choose “Reset Local Configuration”

DEEP Troubleshooting Steps:

  1. Confirm that all ports and cabling are functional:
    • Plug the affected phone in to a different Ethernet port.
    • Switch out the Ethernet cable of the affected phone for a different one.
    • Unplug the affected phone, and try a working phone with the same port/cable.
  2. See if you can access phone’s web interface (GUI) by typing phone’s IP address into a web browser. An inability to access the web GUI is a solid indicator that there is a network problem (such as the phone being on the wrong subnet, which can be confirmed by running ipconfig to compare the phone’s IP with a computer’s on the same network.)
  3. Check firewall settings.
  4. If possible, ensure the phones are passing through only one router (a modem/router combo gateway connected to an additional standalone modem is a potentially problematic setup).
  5. Disable SPI and SIP-ALG in the router (if able) and reboot the router.
  6. Set both primary and secondary DNS on the routers to point to a public DNS such as 8.8.8.8 or 8.8.4.4, then perform a network power cycle.

Call 8X8 and have them reset the phone to factory settings and push the configuration file to the phone. If the phones config file and the PBX file do not match due to file corruption the phone will show this error.
