Sony MW600 doesn't work call function with lumia 1520

[WPCentral Question]

I have Sony MW600 bluetooth headset.
I try pairing lumia 1520 success and can play music listening but not work bluetooth call function.
So I try MW600 pairing with Android phone, it can all functions(listening music and bluetooth call).
Why not work bluetooth call with lumia 1520?
Sony MW600 is not compatibility lumia 1520?

The MW600 behaves in this way with any WP I've tried with it (my old Lumia 920, then a 925 and 520 in a Nokia dealership). No luck with any of them.

That's really strange... I have a Sony Ericsson MW600 and it worked fine for calls and music with my Lumia 925. I can't remember if a long press on the call button would allow voice command - i think not but simple answer/hang up worked okay - and sound was fine.
