Hi All,
After registering my Jabra Freespeak on the web, I noticed a feature of the non-Bluetooth version that isn't included in the manual: the phone button on the headset can pick up, end or voice-dial calls.
I found it at: http://www.jabra.com/fscs/NBFreeSpea...dFeatures.html

I was just about to return my Freespeak to Verizon, when I discovered this feature, and found that it works like a charm on my v60i! Most phones that have a headset feature with a call button should work with this. I recently purchased the stereo headset for the 7135, so I expect the 7135 will also support this feature using the bluetooth converter.
