Graphical display

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

Video

   720p HD video (encode and decode)

   H.264 and Cisco Application Visibility and Control (AVC)

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 by using   industry-standard inline handset amplifiers such as Walker Equipment W-10 or   CE-100 amplifiers. The dial pad is also ADA-compliant

Speakerphone

   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

External audio ports

   The phone has a 3.5-mm stereo line in/out jack (for optional external   headset, speakers, or headphones)

USB

   Two USB ports enhance the usability of call handling by enabling wired   or wireless headsets, in addition to providing charging capability to mobile   devices such as smartphones or tablets

     A side USB port provides up to 500mA power output at 5V or 2.5W

     A back USB (in yellow) port provides 500mA power output and is   upgradable to support up to 2.1A power output at 5V or 10.5W

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

Bluetooth

   The phone offers Bluetooth 4.1 LE, Enhanced Data Rate (EDR) Class 1   technology (up to 66-ft [20m] range)

   Hands-Free   Profile (HFP) is supported for untethered headset connections and voice   communications

   Phone Book   Access Profile (PBAP) is supported for phone book object exchange between   devices

Wi-Fi client

   As an alternative to wired Ethernet, the 8865 supports a Wi-Fi radio   with integrated antenna enabling connectivity to a Wi-Fi access-point   infrastructure, thereby saving on the labor costs of pulling Ethernet cables   to every work location. Complete Wi-Fi specifications are included in Table 3   later in this document
