Cisco 8841 SIP Phone

The Cisco 8841 is a SIP Phone with 5 programmable line keys that can be tailored for directory numbers or certain call features, such as speed dial and BLF. It boasts a sizable 5-Inch colour display, dual Gigabit Ethernet ports, High Definition audio, a handsfree speakerphone, and corded/cordless headset compatibility. The 8800 SIP Series is PoE-powered; a PSU (sold separately) is necessary to use in non-PoE settings.

Please note: This SIP phone is part of Cisco's Multiplatform series and is not compatible with the Cisco Call Manager.

This multiplatform phone firmware enables the 8800 Series to work with third-party call control systems.

For partners who provide voice and video services to end customers on third-party platforms, Cisco offers specific firmware loads that support these platforms and run on the Cisco® IP Phone 8800 Series. The feature set provided by this firmware is not identical to that of the firmware designed and built for use with Cisco call control systems, but there are many similarities. For clarity, this data sheet focuses only on the features provided on these multiplatform phone firmware loads.

The Cisco 8841 supports five programmable line keys, which you can configure to support either multiple directory numbers or calling features such as speed dial / BLF.
