Motorola Milestone : Missing Calls While Using Apps / Caller Goes Directly To Voice Mail

When I am using Apps, IE. Facebook, Messing, or Browseing the web, I miss incoming calls, the caller (WIFE and others) goes directly to my voice mail, I have checked to see it the check box in the contacts section is check or not (the one that tells the contact to go to VM), and it is UNCHECKED, yet calls still goto VM, the even go to VM after i am done surfen or Texting, is there some way to tell the phone or a check box that i can check to accept all incoming calls no mater what i am doing, i have even called CS to see if CALL FWDing got turned on some how, they told me nope!
