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.

Services

The Cisco Unified IP Conference Station 7937G allows users to quickly access diverse information such as weather, stocks, quote of the day, or any Web-based information. The Cisco Unified IP Conference Station 7937G uses XML to provide a portal to an ever-growing world of applications, features, and information.

Help

The online Help feature gives users information about the phone keys, buttons, and features. The pixel display allows for more flexible feature navigation and significantly expands the information viewed when using features such as Services, Information, Messages, and Directory. For example, the Directory button can show local and server-based directory information.

Hold, Mute, and Redial Keys

The Mute key is a fixed key. When it is active, the LED flashes on the Cisco Unified IP Conference Station 7937G as well as on the optional microphone kit. Hold and Redial are provided as soft keys associated with the screen, and are always at the same position for easy access.

Display

The Conference Station has a large high-resolution, graphical 32 level grayscale, backlit display (255 x 128 pixels).

Speakerphone

The Cisco Unified IP Conference Station 7937G offers full duplex high-quality wideband speakerphone technology.
