                module.version = "6.0-dirty"

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
This( Above) is the normal condition -- if I make a call I can't transfer my Smart Phone voice to Bluetooth Device/
then if I do loopback it allows to transfer Voice from Phone to Bluetooth device ( no sound at Phone , making sure that Conversation has transferred to BT Device) 


#pacmd load-module module-loopback source=bluez_source.F8_32_E4_FB_FD_28 sink=alsa_output.usb-Jabra_Jabra_UC_VOICE_150_duo_000000000000-00-duo.analog-stereo

again whatever I 'm speaking over MIC I 'm able to listen in headphone Speaker. But Voice conversation is missing which supposed to get via Bluetooth

Maybe the module-loopback source output got moved from the bluez source to the alsa source for some reason? You can verify what streams are connected to what devices with "pactl list", and prevent unwanted source output moves from happening by giving parameter "source_dont_move=true" to module-loopback ("sink_dont_move" exists too, which will prevent the sink input from moving from the initial sink to somewhere else).
