[asterisk-users] chan_bluetooth - one way audio

[Danko Miocevic]

I have compiled chan_bluetooth and I have used it many times before... but 
now I have a problem and I can´t find a solution. I have a bluetooth dongle 
(MSI) connected to my asterisk and I use a V3 phone to make calls to another 
cell phones... the thing is that I just get one way audio.. I can hear 
people from my IAX softphone but they can´t hear me... I don´t know what 
could be.. anyone had the same problem? Thanks for your time,
                                                                             
                                                                             
                Danko

This is my bluetooth.conf

[general]
; Channel we listen on as a HS (Headset)
rfchannel_ag = 7
; hci interface to use (number - e.g '0')
interface = 0


;; Some phone example

[00:14:9A:F8:EB:E7]
name        = V3        ; The name of the phone
channel     = 3                 ; The channel used by the HS audio gateway 
profi
le
autoconnect = yes       ; Tells chan_bluetooth to establish link at startup
type        = AG
