The Cisco Unified IP Phone 6900 Series is a complementary addition to
the Cisco Unified IP Phone portfolio for enterprises that includes the
Cisco Unified IP Phone 3900 and IP Phone 7900 Series.
The Cisco Unified IP Phone 6900 Series introduces a simple and earth-
friendly ergonomic design, delivering an enhanced user experience for
customers seeking cost-effective, robust voice communication
services with traditional telephony-like user experience. This phone is an
ideal solution for enterprise campus, enterprise branch office, satellite office, remote teleworking, and contact
center environments.
The Cisco Unified IP Phone 6900 Series also brings a more responsible design with earth-friendly
enhancements to reduce power consumption and increase energy savings for customers. These phones take
advantage of recyclable and reground plastics and offer a deep-sleep mode option, which reduces power
consumption in off-work hours and offers 50-percent power savings versus normal daytime use.
