Q: Will the PC/Phone Headset Switch work with my Cisco Phone? PC/Switch A: The PC/Switch (part # 05344-42) will work if you’re plugging a headset into the phone’s handset port. For example, most wireless headsets using a handset lifter will work fine. The PC/Switch will not work if you’re plugging your headset into the headset port and using a pre-programmed headset button. This port is wired backwards from traditional wiring thus not allowing corded headsets with a direct connect cable to use the PC/Switch.
