How to enable bluetooth A2DP Sink profile service in android phone / tablet?

[vss pravin]

We need an application that will enable an android device (a tablet for instance) to act as a Bluetooth headset and dial-er for another phone.

Is it possible to implement this by enabling bluetooth A2DP Sink profile service?

Can anyone guide me about how to enable bluetooth A2DP Sink or implement the above process.

Is there any application level api in the new version of android (Lollipop)

Seems, that no one is interested. What a pitty, it could be really HOT stuff. For example, cheap android phone pluged instantly to a charger and to Car Audio via AUX, and You have got Bluetooth automatic pairing system for calling and music, navi etc.

Unfortunately I couldn't find solution for this, neither the app. It is strange. Some people says, that Android can not be a sink (reciever) in a2dp profile. So how does microphones from earphones are streaming audio to a phone, hmm?
Maybe someone will do it
