Cisco IP Communicator is a softphone client which runs on the Agents computer, just like Cisco Finesse (or Cisco Agent Desktop if you're still using that). Therefore, if the Agent were to secure their communication on the computer with a VPN to the Enterprise network, not only would Cisco Finesse work, but the softphone would register and work too. The Agent would now just need a headset they could use on their computer to hear and speak to the caller. Like a USB headset for example.
