Examine the quick disconnect cable connecting the headset to the phone and ensure it is a Plantronics Polaris U10P.
The identifying markings should be etched onto the larger end of the cable connector.

If it is the wrong cable, we recommend ordering the U10P by either:
- contacting 8x8 Sales at 1-866-835-2979.
- ordering directly from VoIP Supply at http://www.voipsupply.com/27190-01.
If you are already using the U10P, contact 8x8 Technical Support so we can help resolve your call quality issues.
