I think it may be a feature not on the MOTO headsets - on some Plantronics headsets, like the 510, they boast the ability to seamlessly connect to multiple devices. I would think this is something that allows you to set it up to connect to both - maybe not at the same time though as it may be a secutiry issue. Just thought I would pass that along.
