| Features | Benefits |
| Ergonomic design | The phone offers an easy-to-use interface and provides a traditional telephony-like user experience. |
| Graphical display | The 5-in., 800 × 480 resolution, grayscale 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). You can achieve Section 508 loudness requirements 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 | The 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 an 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
Messaging, Application, and Directory keys

| Backlit Indicator | The phone supports backlit indicators for the audio path keys (handset, headset, and speakerphone), select key, line keys, and message waiting. |
| Replaceable bezel | The phone includes a black bezel; an optional silver bezel is also available 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 (available 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. |
