Again i can see the audio levels changing in pavucontrol (connected from external machine with PULSE_SERVER) but only one side audio is working which is from device side mic to other end.  on the other side (calling phone to device) the levels are changing but seems to be not routed to the default sink (since the levels are not changing in the default sink)

What does pacmd list-cards show? Is the bluez device listed there? Can 
you check (with pavucontrol
or in the logs) if the loopback from the phone goes to the correct sink? 
Do you see messages in the
pulseaudio debug log from both loopback modules?
