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.

The Cisco® IP Phone 8841 is a business-class collaboration endpoint that delivers high-fidelity, reliable, secure, and scalable voice communication for small to large enterprise businesses.

Cisco® IP Phone 8841

With the Cisco IP Phone 8841, you can increase personal productivity through an engaging user experience that is both powerful and easy-to-use. The IP Phone 8841 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 communication features from Cisco on-premises and hosted infrastructure platforms and third party hosted call control.

The Cisco IP Phone 8841 offers five programmable line keys. You can configure keys to support either multiple directory numbers or call 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 8841 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 follow:

     The Cisco IP Phone 8841 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 supports a built-in Gigabit Ethernet switch for your PC connection.

     Support for Cisco EnergyWise technology makes the Cisco IP Phone 8841 more energy-efficient and ecofriendly; the phone is qualified by Energy Star organization.

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