An Overview of the Cisco Unified IP
Video Phone
The Cisco Unified IP Video Phone 7985G provides business quality video over
the same data network that your computer uses. The Cisco Unified IP Video
Phone 7985G, which is designed for the individual workspace, makes a video
meeting as simple as a telephone call. The video phone provides the same softkey
functionality and features as a Cisco Unified IP Phone, allowing you to place and
receive calls, put calls on hold, transfer calls, make conference calls, and so on.
The Cisco Unified IP Phone 7985G also provides a color screen, support for up to
eight line or speed dial numbers, context-sensitive online help for buttons and
feature, and a variety of other sophisticated functions.
You must configure and manage the Cisco Unified IP Phone 7985G like other
network devices. The phone supports G.711, G.722, G.729, G.729b, G.729ab
audio codecs and H.261, H.263 and H.264 video codes.
