Product Description
The
Grandstream GXP-2000 is a next generation enterprise IP telephone
designed to handle the high demand of today's office environment. The
GXP-2000 uses innovative technologies such as advanced Digital Signal Processing (DSP)
and patent pending adaptive jitter buffer control
to attain superb sound quality. The phone is easy to configure via the
keypad and web interface or can be personalized via a central configuration file
for large scale deployments. The Grandstream GXP-2000 dramatically reduces the
cost of converging voice and data networks when compared to other enterprise
IP phone alternatives, yet it maintains the features and reliability
necessary to excel in a high demand environment.
