I have the same issue with Pandora. If I have it hooked up to my car through a 3.5mm audio cable and someone calls, you have to leave the audio cable in and make the phone call over your car speakers otherwise if you unplug the phone to make a call like normal, you cannot hear the other person through the phone itself (but they can hear you). My boss has this same issue too. I think it's because if you unplug the audio cable on an incoming call, the Droid thinks there is still something plugged into it. That is the extent of my knowledge at least.

BTW, stock ROM, but rooted. Boss's is stock everything.
