I am running the following firmware on the phones:
9951 - sip9951.9-2-3-27
I checked and this is the latest which is available on CCO. I haven't tried an older firmware as of yet but I might give that a try. Also we purchased the ICON because that was the headset recommended by Cisco.
I have the same problem with a icon, but in my case the bluetooth connection diconnect after 10 seconds talking on the first line. The line is not disconnected, you can put up the handset to have audio again.
It is only between 9951 devices and 7945 devices. If you do the same test between two 9951 devices the bluetooth connection is ok al the time.
