We'd like to have the displays/menus time out on the 7960G and 7941 phones. We have a 7970 on site which has this feature. Anything available for the other models? Perhaps a firmware upgrade? Phone currently on v8.0(5.0) and Call Manager 4.2.
This feature is currently only available in the "color" models, 7945/7965 7970/7971 and 7975.
