From August 2008 the Plantronics Polaris range of headsets will be discontinued. The Polaris range was initially designed for Nortel/Meridian telephones and the purchase of a Polaris headset included an unamplified connection cable. Going forward after August 2008, you will need to use the Plantronics H-series headset with an amplified A10-11/A bottom cable, which are available on this site at £15.00 + VAT.
