I have a message in my voicemail on my cell phone that I want to get into my computer. Can this be done through the hands free headphone jack on the phone? I'ts not a 1/8" jack though. I've never put one of these on there so I'm not sure what kind of plug it is. I also tried just miking the earpiece and if I crank everything up I can hear it alright, and Sound qaulity isn't a big deal, but when I get the mic close enough to hear the voice I get crazy feedback or something. any suggestions? thanks a bunch!
