Cisco 8841 SIP Phone with Multiplatform Phone Firmware

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.
