What is Cisco IP Communicator?

First, a quick refresher. Cisco IP Communicator (CIPC) is a software-based phone application. It allowed users to make VoIP calls directly from a PC using a headset, effectively turning a laptop or desktop into a Cisco IP phone (like a 7960 or 7940 model). It was popular in call centers and remote offices during the mid-2000s. Technical Write-Up: Cisco IP Communicator v8

• Limitations: It will not run on modern 64-bit versions of Windows 10 or 11.
