Cisco VoIP - 8851 USB Ports/Mobile Device Charging

Instruction on how to charge mobile devices on 8851 Cisco VOIP phone

The Cisco 8851 has one USB port. The USB port supports a maximum of five USB devices. Each device connected to the port is included in the maximum device count, including any Key Expansion Modules.

For example, your phone can support five USB devices on the side port. Many third-party USB products contain more than one USB device, and thus count as more than one device.

Your phone continues to charge the mobile device while it is in power-saving mode but stops charging in Power Save Plus mode.

When you use your phone to charge your mobile device, the following conditions apply:

If you unplug your tablet and immediately plug in a USB headset to the phone, a 3-second delay occurs before the phone recognizes the USB headset.
