Feature Description
Directories The Cisco Unified IP Conference Station 7937G identifies incoming messages and categorizes
them for users on the screen. This feature allows users to quickly and effectively return calls
using direct dial-back capability. The corporate directory integrates with the Lightweight
Directory Access Protocol Version 3 (LDAPv3) standard directory.
Settings The Settings feature key allows the user to adjust display contrast, select background images
(if available), and select from a large number of unique ringer sounds through the User
Preference menu. Network Configuration preferences also can be set up (usually by the
system administrator). Configuration can be either automatically or manually set up for
Dynamic Host Control Protocol (DHCP), Trivial File Transfer Protocol (TFTP), Cisco Unified
Communications Manager, and backup Cisco Unified Communications Manager instances.
