I’ve discovered recently that it’s even EASIER to phone into a conference call with Skype. Then all you have to do is set up the open source Audacity audio recording program (http://audacity.sourceforge.net/) to record audio from “stereo mix” rather than microphone. Et voila! No extra equipment required. Then you can save the Audacity file and edit at your leisure without having to transfer a file from another device. DO mute your microphone on Skype though, since it does tend to create echoes and other unwanted sounds. You do have to have the landline feature on Skype enabled — it takes $10 to buy a bunch of minutes or somewhere around $30 per year for unlimited long-distance dialing.
I get better sound quality and connection on Skype than I do on my [major carrier] cell phone!
