I have a new Cisco 561 headset on version 2-2-001-3 that is exhibiting some odd issues. When connected it registers and associates to the Cisco 8811 phone. When trying to make calls the audio on the headphone is so low that you can barely hear it. I gave it to my boss who plugged it in via the USB to USB cable and it worked perfectly. I tried it with the split aux/headset cable and it had the audio issue. I thought it might be the cable, but I plugged it in with a known working cable and it is still having the odd audio issue. The phone that this headset is for does not have a USB port, so I can't use that as a solution. Any thoughts?
