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