Description

OVERVIEW:
The Cisco(R) IP Phone 8811 is a cost-effective, business-class collaboration endpoint that delivers high-fidelity, reliable, secure, and scalable voice communications for small to large enterprise businesses.
With the Cisco IP Phone 8811, you can increase personal productivity through an engaging user experience that is both powerful and easy-to-use. The IP Phone 8811 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 and third party hosted call control.
The Cisco IP Phone 8811 supports 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. 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 8811 is one of the models that now reduces the use of natural resources while closing the loop with its own electronic waste.
Ergonomic design: The phone offers an easy-to-use interface and provides a traditional telephony-like user experience.
Graphical display: The 5-in., 800 x 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.
Keys: 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 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.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $15 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Cisco products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
