Cisco 8851 and Sennheiser Officerunner

I am trying to setup a Sennheiser officerunner headset to my 8851 phone. I am using the USB input and the phone is recognizing the headset but audio and the electronic hook-switch is not working. Any suggestions? I do have the recommended USB cable from Sennheiser and also have enable hook-switch control and wideband headset is enabled as well.

Just to make sure, you're using the cable mentioned here:

Have you tried different FW versions? or other device model? Or your laptop using Jabber or some other app?

Hi Jaime,

 

Yes, I am using the cable suggested. This headset did work on a 7945 and 7965 phone in the past. When you say firmware versions do you mean phone firmware or headset?
