[Bluez-users] no audio on plantronics headset

[Jerry Geis <geisj@pagestation.com>]

I have a kensington usb bluetooth adapter 2.0 with a plantronics 510 headset.
When a call is coming from asterisk (chan_bluetooth) with Dial(BLT/PLANTRONICS-HS)
my headset hears the ringing. I press my answer call button and I get NO audio...
I see below there is an error

process_rfcomm_cmd: Unknown AT Command: 'AT+VGM=15' (+VGM=15)

What do I do???

Thanks,

Jerry
