Cisco IP Communicator is a Windows-based software IP phone that registers to CUCM identically to a hardware phone, requiring a device entry and directory number configuration within CUCM to function.

The Cisco IP Phone 8811 is a physical hardware desk phone, not a software application that runs on a user's computer.
