Hi Marcus,

Look in this section for a complete list;

You may want to look at a great new method of using Wireless Headsets that Plantronics and Cisco have developed that work with the 7942/7945, 7962/7965 and 7975 IP Phones only so far. The Plantronics HHC adapter enables hookswitch control and ***ring detection for CS50, CS55, CS60, CS70, CS70N, CS351N, CS361N and V510S wireless headsets, eliminating the need for a an HL10 lifter.)

With the use of an Adaptor Part # APC-4 (called the HHC Adaptor) which plugs into the Aux Port on the base of the phone allows calls to be answered and disconnected via the Headset without the use of the Lifter!

You can't believe how well this new setup works :)
