BlueZ only supports AG(audio Gateway) role at the moment. Also > most phones support only AG role, so in your case which device acts as > the Hands Free device? Sorry for let you misunderstand. In my project, cell phone is used as Audio Gateway. What I am trying to do is to run the Asterisk (Soft PBX) on my PC. As the following scenario shows, my goal is to let each dongle to support 3 phone calls via 3 cell phones. Soft VoIP phone -- Asterisk (PC) ----bluetooth usb dongle-- cell phone1, cell phone 2, cell phone 3. So, first I need to figure out how much concurrent SCO can one usb dongle support in bluez (as you suggested the btsco. I will try it right now) The second thing is to test the voice call via the cell phone, that's why I want to write some short program to test 2 voice connections to 2 cell phones.
