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.
