Product Info
The Cisco 8851 multiplatform phone firmware enables the 8800 Series to interact seamlessly with third-party call control systems. This firmware offers many features comparable to Cisco's own call control platform, though it's not completely identical. You can configure the phone's five programmable line keys to fit your needs, such as multiple directory numbers or speed dial / BLF. Additionally, it's compatible with up to two 8800 Key Expansion Modules for even more programmable funtion keys.
