configurable line buttons, and a variety of other functions to meet the
communications needs of business with moderate telephone traffic and specific
call requirements. Dedicated hold, redial, and transfer keys facilitate call
handling. Illuminated mute and speakerphone keys give a clear indication of
speaker status.
The Cisco Unified IP Phone, like other network devices, must be configured and
managed. The phone encodes G.711a, G.711u, G.729a, G.729ab, G.728/iLBC,
