The Cisco® Unified IP Conference Station 7935 (Figure 1) couples state-of-the-art conference-room speakerphone technologies from Polycom with the award-winning Cisco Unified Communication solutions. The net result is a conference-room phone that offers superior voice and microphone quality with simplified wiring and administrative cost benefits derived by converging voice, video, and data across a common IP infrastructure.

The Cisco Unified IP Conference Station 7935 voice instrument is a full-featured, IP-based, full-duplex hands-free conference station for use on desktops and offices and in small to medium-sized conference rooms. This device easily attaches to a Cisco Catalyst ® 10/100 Ethernet switch port with a simple RJ-45 connection and dynamically configures itself to the IP network through the Dynamic Host Control Protocol (DHCP). Other than connecting the Cisco Unified IP Conference Station 7935 to an Ethernet switch port, no further administration is necessary. The Cisco Unified IP Conference Station 7935 dynamically registers with the Cisco Unified Communications Manager for connection services and receives the appropriate endpoint phone number and any software enhancements or personalized settings that are preloaded in Cisco Unified Communications Manager.
The Cisco Unified IP Conference Station 7935 full-duplex design offers superior voice quality, eliminating echoes, clipped words, and reverberations for more natural conversation. It features superior sound quality with a digitally tuned speaker and three microphones, allowing conference participants to move around while speaking. In addition to the regular telephony keypad, the Cisco Unified IP Conference Station 7935 provides three soft keys and menu navigation keys that guide a user through call features and functions. The Cisco Unified IP Conference Station 7935 also features a pixel-based LCD display. The display provides features such as date and time, calling party name, calling party number, digits dialed, and feature and line status.
