The Cisco CP-521G=
phones are an excellent choice for customers undergoing the transition
from traditional digital or hybrid key systems (KTS) and PBXs to a
system based on the Cisco Unified Communication 500 Series. The Cisco
Unified IP Phones 500 Series can easily be integrated into the Cisco
Smart Business Communications System. They can be used in cubicles,
retail settings, classrooms, breakrooms, lobbies, and manufacturing
areas.
These phones are optimized to replace traditional voice systems, or
to layer a next-generation voice solution into a Category 5 (CAT5)
wired environment. The Cisco Unified IP Phone 521G is a single-line IP
phone with two call line appearances. Four dynamic soft keys on each
phone guide you through core business features and functions, while a
backlit pixel-based display combines intuitive features, calling
information, and device system information to give you information at
your fingertips.
The phones are in line with Cisco Green, incorporating power
efficiency features such as LCD shutoff to save power when the phone is
not in use. This phone can also be used with productivity-enhancing
features such as directory search and VoiceView Express.
