How to unlock Cisco SPA122 ATA if 7932# returns "invalid option"

admin

If you can't enable browser access to a Cisco SPA122 ATA but get the reply "invalid option" after entering **** and then 7932#, even after factory reset, here is a workaround which works by temporarily swapping the network cables.

Many thanks to Stephan_Rackco for kindly sharing the solution.

Unlock Cisco SPA122 ATA for browser access

• Connect WAN to Internet port
• Connect any PC/Laptop to the Ethernet Port ( make sure your device is set to get a DHCP address )
• The Cisco ATA 122 will assign your device an IP ( typically 192.168.15.100 )
• Open a browser on your PC/Laptop and go to http://192.168.15.1 and login with default user/pass which is admin/admin
• In configuration menu change default admin pass to a new password, while you are here enable WAN admin access.
