Thanks, SCO transport is working now, even though i cant hear anything on headset sco traffic is visible via btmon during phone call.The issues were,

* The build system(Yocto) was not properly enabling the ofono backend for pulseaudio, took some time to identify this.
* Configured default.pa with proper module name name(module-bluez5-discover) and arguments
* device, module and card restore modules are causing issues, so disabled it !! 

Currently trying to change volume with alsamixer is giving following message,

    alsa-plugins-1.0.29/pulse/pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused
    cannot open mixer: Connection refused

Best Regards,
John J
