What steps would be necessary to connect an iPhone 4S to a Windows 7 desktop computer, and then to accept a phone call from the microphone/headset on my computer? I'm essentially looking to pair my iPhone to my computer in the same manner in which it has been paired with my automobile.
I'm just throwing this idea out there, it is probably flawed in some way, haha.
If you bought the following or something like it, I think you could run a stereo mini cable from the pc to an adapter that splits it into 2 RCA cables (amazon has the cables in a package deal with the mixer). Plug that into the mixer. Do the same thing from the iphone's headphone jack.
Grab the headphone adapter and listen directly to the mixer. You now will have sepperate volume controls for the device right there in front of you! Is that kind of what you're wanting to accomplish?
