It would be a lot easier just hold the phone mouthpiece/mic next to the PC speaker!

Any instant messaging software on the PC, such as Skype, already uses the sound card to send audio via a modem (which has built-in safety features). It's all been done for you. Isn't that enough?

look at the info and circuits on epanorama and make somthing from the parts you have. Using a transformer would be best.
