Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco IP Phone 8861

The Cisco® IP Phone 8861 is a business-class collaboration endpoint that combines high-fidelity, reliable, secure, and scalable voice over IP communications with Cisco Intelligent Proximity for telephony integration for personal mobile devices to support small to large enterprise businesses.

With the IP Phone 8861, you can increase personal productivity through an engaging user experience that is both powerful and easy-to-use. The IP Phone 8861 combines an attractive new ergonomic design with wideband audio for crystal clear voice communications, “always-on” reliability, encrypted voice communications to enhance security, and access to a comprehensive suite of unified communications features from Cisco on-premises and hosted infrastructure platforms. The IP Phone 8861 also can be supported on third party hosted call control services.

In addition, Cisco Intelligent Proximity brings the worlds of desk and mobile together for you when you are using your mobile device at the desk for your work. You can move the audio path over to the IP Phone 8861 during active mobile calls to take advantage of its superior audio acoustics. An example would be to share a conversation with a colleague who you want to listen in. This capability gives you greater flexibility and a superior user experience when at your desk.

The IP Phone 8861 comes standard with two USB ports so you can charge your personal mobile devices when at your desk, and stay connected when away from your desk.

The Cisco IP Phone 8861 offers five programmable line keys. You can configure keys to support either multiple directory numbers or calling features such as speed dial. You can also boost productivity by handling multiple calls for each directory number using the multicall-per-line feature. Fixed-function keys give you one-touch access to applications, messaging, directory, as well as often-used calling features such as hold/resume, transfer, and conference. A five-way navigation cluster helps you transition through menus more easily. Backlit acoustic keys provide flexibility for audio path selection and switching.

Additionally, Cisco has adopted circular design principles in its products by pioneering the use of post-consumer recycled plastic. The 8861 is one of the models that now reduces the use of natural resources while closing the loop with its own electronic waste. Learn more about what this means by visiting the Cisco’s Circular Economy website.

Other key features of the phone include:

     The Cisco IP Phone 8861 offers a 5-in. high-resolution (800 x 480) widescreen VGA backlit color display. Localized language support, including right-to-left on-screen text, meets the needs of global users.

     The phone offers a built-in Gigabit Ethernet switch for both network connection and your PC connection.

     The phone also supports campuses with 802.11a/b/g/n/ac WLAN enabled.

     Support for Cisco EnergyWise technology makes the Cisco IP Phone 8861 more energy-efficient and ecofriendly; the phone is qualified by the Energy Star organization.

     An optional wall-mount kit is orderable as a spare part for customers seeking this capability.

     Up to three optional IP Phone 8800 Key Expansion Modules can be supported for 108 additional line/feature keys.

     Charcoal and white color options.

Features and benefits

Table 1 lists features and benefits of the Cisco IP Phone 8861.

Table 1.           Features and benefits



Hardware Features

Ergonomic design

  The phone offers an easy-to-use interface and provides a traditional telephony-like user experience.

Graphical display

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


  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.

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.

External audio ports

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


  Two USB ports enhance the usability of call handling by enabling wired or wireless headsets, as well as provide 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 upgradeable 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 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.


  The phone offers Bluetooth 3.0 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 Cisco IP Phone 8861 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 4 later in this document.


  The phone has the following keys:

      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

      Standard keypad

      Volume-control toggle key

      Speakerphone, headset, and mute 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 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.


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

Key Expansion Module (KEM)

  The phone supports up to three KEMs to expand from 5- to 113-line buttons. You have the convenience of many speed dials or programmable features.

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 4. 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
