Table 2. Detailed Features of Cisco Unified IP Conference Station 7937G

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. Included are Automatic Gain Control, Comfort Noise Generation, Silence Suppression/Voice Activity Detection, Echo Suppression, and Dynamic Noise Reduction, which reduces noise by up to 9 dB from constant noise sources such as fans or HVAC systems.
Ethernet Switch	The internal Ethernet port allows for a direct connection to a 10/100BASE-T Ethernet network through an RJ-45 interface with single LAN connectivity for the Cisco Unified IP Conference Station 7937G. Co-locating a PC with the Cisco Unified IP Conference Station 7937G is not supported.
Volume Control	The convenient Volume Control buttons on Cisco Unified IP Conference Station 7937G provide for easy, decibel-level adjustments for the speakerphone and ringer.
Flexible Power Options	The Cisco Unified Conference Station 7937G supports IEEE 803.af PoE Class 3, which allows powering from any of the Cisco Inline Power-capable blades and boxes. In addition, the Conference Station can be powered locally with a power supply (part number CP-PWR-CUBE-3) when combined with the Cisco Unified IP Conference Station 7937G Power Splitter.
Multiple Ring Tones	Twenty-eight user-adjustable ring tones are available.
Signaling Protocol Support	The Cisco Unified IP Conference Station 7937G supports Skinny Client Control Protocol (SCCP).
Codec Support	G.711, G.729, and G.722 audio compression codecs are available.
Quality of Service (QoS) Options	The Cisco Unified IP Conference Station 7937G supports DHCP and 802.1Q/p standards. The Conference Station can also be configured with an 801.1Q VLAN header containing the VLAN ID overrides configured by the Admin VLAN ID.
Security	The Cisco Unified IP Conference Station 7937G supports device authentication via 802.1.x supplicant and 802.1x MD5-EAP.
Language Support	More than 30 languages will be supported within 6 months of FCS (dependent on Cisco Unified Communications Manager version).
Configuration Options	IP address assignment can be statically configured or configured through the DHCP client.
Voice Quality	Comfort-noise generation and voice activity detection (VAD) programming are performed on a system basis.
