[pulseaudio-discuss] Switching bluetooth profile internally

[Sathish Narasimman]

Hi,

My application is almost similar to what VOIP application.
I am trying to create a communication between the laptop and headset.
That is Tx and Rx full-duplex communication between the laptop and
Bluetooth headset.

Also can you please mention the VOIP application that works well with Ubuntu.
I tried skype and it is not working with Bluetooth.
