Motorola V710
i have a way to make phone ring with headset
turn on your BT headset ( i have the 820)
now go to BT link then handsfree and drop the head set
now they are disconnected and the phone will ring
you can answer the phone at the handset or push the button and the headset will connect
here is the problem
after the call you have to drop the headset again
it works well though if you don't want to keep the headset on but instead want to pick it up and put it on to answer calls better then turning on the headset every time
let me know what you think
