I have Option GTM378 WWAN Card installed in my Sony Vaio Z11WN/B. I have read that it supports GPS and Voice functions, I managed to enable and configure GPS option and it is fully functional but I am still unable to enable Voice support.
Can anyone please guide me how to enable voice support on my Option GTM378 WWAN Card

From my experience, voice support usually requires a program which is available from the manufacturer.
