If you are unable to ping the IP address of the SPA 8800 (when connected to a Cisco SMB switch) after it had already been provisioned with the BE3000, it is likely that you are hitting a known issue with the SPA 8800/BE3000. To resolve the issue enable CDP by doing the following
- Connect your PC directly to the Aux port on the SPA 8800. It will provide you an IP address.
- Look up the default gateway of your PC. Plug the IP into a browser and access the SPA 8800. Click on Admin User and Advanced ( Top right had corner of screen)
- Disable the TFTP provisoning for SPA 8800 (Voice-> Provisioning) and enable CDP (Network-> WAN Status-> Enable CDP).
After you save and exit, you should now be able to ping the SPA 8800. This bug is likely to be resolved in the next version of the BE3K (8.6.5).
