Graphical display

● The 800 × 480, 24-bit color, 5-in. WVGA display provides scrollable access to calling features and text-based XML applications.

Handset

● The handset is a standard wideband-capable audio handset (connects through an RJ-9 port).
● The standard coiled cord has a custom end for concealed cable routing beneath the phone (cord length is approximately 21 in. [55
cm] coiled and up to 72 in. (183 cm) extended).
● The handset is Hearing Aid-Compatible (HAC) and meets Federal Communications Commission (FCC) loudness requirements for the
Americans with Disabilities Act (ADA). Section 508 loudness requirements can be achieved using industry-standard inline handset
amplifiers such as Walker Equipment W-10 or CE-100 amplifiers. The dial pad is also ADA-compliant.

Speaker phone

● A full-duplex speakerphone gives you flexibility in placing and receiving calls with hands free. For added security, the audible
Dual Tone Multifrequency (DTMF) tones are masked when the speakerphone mode is used.

Analog headset

● The analog headset jack is a standard wideband-capable RJ-9 audio port.

AUX port

● You can use an auxiliary port to support electronic hookswitch control with a third-party headset connected to it.

Ethernet switch

● An internal 2-port Cisco Ethernet switch allows for a direct connection to a 10/100/1000BASE-T Ethernet network (IEEE
802.3i/802.3u/802.3ab) through a RJ-45 interface with single LAN connectivity for both the phone and a co-located PC.
● The system administrator can designate separate VLANs (IEEE 802.1Q) for the PC and phone, providing improved security and
reliability of voice and data traffic.

◦ Line keys
◦ Soft keys
◦ Back and release keys
◦ Four-way navigation and select keys
◦ Hold/Resume, Transfer, and Conference keys

message waiting.

Replaceable bezel

● The phone includes a black bezel; an optional silver bezel is also orderable separately.

Dual-position foot stand

● The display is easy-to-view and the buttons and keys are easy-to-use. The two-position foot stand supports viewing angles of 35
and 50 degrees; you can remove the foot stand for wall mounting, with mounting holes located on the base of the phone.

Wall-mountable

● You can install the phone on a wall using an optional wall-mount kit (orderable separately).

Physical security

● The phone is compatible with the Kensington Security Slot (K-Slot) antitheft system.

Power Features

IEEE Power over Ethernet (PoE)

● IEEE Power over Ethernet class 2. The phone is compatible with both IEEE 802.3af and 802.3at switch blades and supports both
Cisco Discovery Protocol and Link Layer Discovery Protocol - Power over Ethernet (LLDP-PoE).

Cisco IP Phone Power Cube 4

● This optional power cube is used as an AC-to-DC (48V) power supply for non-PoE deployments. Use of the power cube 4 also
requires the use of one of the corresponding AC country cords.
