Dialtone when trying to turn my Sennheiser headset on. Also doesn't let me switch back to telephone

Question

I have a Sennheiser OfficeRunner headset using the HeadSetup software and the automatic handset lifter.
For the past 6 months it's worked FLAWLESSLY:
When I would remove the headset from the base, the headset would be in PC Audio mode. When not on the phone, I got all my PC audio through the headset... when the phone rang, I got a ringing in my headset and I could hit a button on the headset or the headset
base and it would flip to the phone and pickup the handset. When done with the call, I could hit the button on the headset or base and the phone would hang up and return to PC mode.
Starting the other day, whenever lync was running, the PC Audio mode would not automatically enable. Pressing the handset or base button would make lync flash and I would get a dialtone for a second then my headset would turn off.
When the phone rings and I would hit the button, the phone would pick up and then immediately hang back up and cause Lync to start flashing again.
When Lync is turned off it works fine.
The button on my headset should have NO effect on my Lync.
Why is this happening and how do I get it to stop?
We do not have phone integration with our Lync here.
I can't run Lync now because it won't let me pick up my actual phone. The handset lifter lifts and then Lync takes over and the handset gets hung up...

Answer 1

Hi,Chapel976,
Did you run Lync when you get the headset work in the past 2 months?
Did you tested it on another computer to see if the same issue happened?
Have you changed anything around this happened,such as some configuration,updates or new applications?
Would you please try to reinstall the headset driver on the computer?
Also please verify the Lync version and make sure it's fully patched.
