Centrafuse is capable of a BT phone connection for calls. It can be hit & miss for proper operation though depending on phone, computer hardware, etc. I'm sure there are others out there as well. As far as SMS, I don't think CF can do that.
I can't get it working in CF. It says bluetooth not found.
I found BlueSoleil but haven't purchased it yet.
Looks like there is a plugin called cPhoneTool that lets you do this stuff
If anyone knows how to configure Centrafuse for phone calls this would b of great help
