My Plantronics bluetooth headset that came with my Plantronics voyager 510 base is broken. Before I spend $50 for a new headset, I wanted to find out if I could pair my Motorola H715 headset that I use with my cell phone with my Voyoger base. I like my Motorola headset. Is it possible and how do I put the Motorola headset in pairing mode? George
