Yes, I can. The on-off button can be reconfigured to do answer-end emulation: http://www.jabra.com/fscs/NBFreeSpea...dFeatures.html

I do occasionally get out of synch with the phone, where I think I am hanging up, but the call has already ended and it goes into voice dial mode, but since the button also shuts off power to the earpiece I don't know it. Then I get into this viscious cycle of hitting the button and having it do the opposite of what I want to happen until I open the flip and manually enter the mode the headset thinks the phone is in. Just takes some getting used to.
