Security Settings
The "Enable recent calls" selection enables / disables keeping a list of the last
phone calls made from or to the CS-700. When disabled no information on the
calls will be kept on the system.
When "Require HTTPS" is enabled, the web interface will switch from http to
https. Please note that when using HTTPS, the CS-700 device does not have a
certified security certificate and the web browser will warn of a potentially
unsecure connection.
"Enable Telnet access" allows the Telnet interface into the CS-700 to be
opened. Changing this setting will reboot the CS-700 unit. Username and
factory default password for the Telnet access are roomcontrol and Yamaha-
CS-700, respectively.
The telnet password for the roomcontrol user can be changed. Enter the
password of your choice, and confirm it.
