    I've been using this headset for the last year and a half and I really like it. Easy to use and I almost forget it on my ear when I wear it. But recently, with a firmware update on my Cisco phone, I coudn't hear any "bips" for incoming calls anymore. Had to go back to an previous version of the firmware on the phone and headset was fully operational again. Maybe Cisco should check this problem with firmware updates ?

    All sales, no useful information. SHOW THE CONNECTION INFO! I don't even know if this will connect to a deskphone.
