For some reason my iMac seems to be picking up phone calls. I can faintly hear the conversation if I turn the volume all the way up on my computer. What is this??? I even disconnected from my wireless network thinking that somehow my DSL had a line crossed somewhere but it was still happening. I had something similar happen with a Dell tower running Win7. Turning everything off and starting back up seems to kick the connection but how do I keep it form happening again and is it two way? Thanks in advance for any help!
