On a motorola flip, I've had to leave the unit flipped open. If you set the phone up to answer when opened, then phoco will work. Also look at lengthy phoco thread from robby/sonic, in there you will see some downfalls to using motorola (single bluetooth connection). The audio bridge is a timing issue about 2 seconds to transfer to and then 6 seconds after the hangup to reload the communications port again after you initiate the "HSPDISCONNECT" in your phoco skin, also add the "RESUME_PHOCO" command for ease of when the phone/phoco doesn't sync or loses the connection between phone to headset and back again.
You will find that phoco is a time consuming project and it's not black and white. Thanks to robbie we now have even a better shot at it when embedded with RR. The phone option for RR is still up in the air, there's RRmobile which a lot of us are trying and watching.
