Features and Benefits




Industrial design

The phone offers a highly usable and intuitive arrangement of lines, features, and calls. Transfer, Conference, and Hold appear on hard keys to reduce the number of presented softkeys to a maximum of 4 per call state.


You can order this model in arctic white or charcoal gray. Handsets are available internationally as slimline (140g) or standard (170g), and you can mix and match them in your work environment to enable a feeling of customization and ownership among your team.


The phone delivers VGA presentation for calling, video calling, and applications, in addition to a 5-inch (10-cm) graphical TFT color display, 24-bit color depth, 640 x 480 effective pixel resolution, and backlighting. The display also supports localization requiring double-byte Unicode encoding for fonts.


An internal 2-port Cisco Ethernet switch allows for a direct connection to a 10/100/1000BASE-T Ethernet network through an RJ-45 interface with single LAN connectivity for both the phone and a co-located PC. The system administrator can designate separate VLANs (802.1Q) for the PC and phone, providing improved security and reliability of voice and data traffic.


Mobility is possible for headset users within 30 feet of their desktop, so you can go to the printer, a colleagues desk, or nearby private location while on a call.


Two USB ports increase the usability of call handling and applications by enabling accessories such as the Cisco Unified Video Camera and wired headsets.

External audio ports

General-purpose audio-in and audio-out ports enable a relaxed speakerphone experience over external speakers and the microphone.

Five lines expanding to 77 with 2 key expansion modules

The phone offers many speed dials and programmable features, so you can follow the activity of many lines. Up to 200 calls per device are supported.
