I work for a market research company that conducts interviews over the telephone, and there are times when we have to tape a phone interview and send it to our clients. Well, one of our clients is being difficult, and rather then sending them a tape, they want us to save the conversation to an audio file and post it to their FTP.
What would I need to save both sides of the conversation (our end and the person on the other side of the line) to an audio file? Is there hardware out there that will connect a phone to an audio card or something like this? And software that I could use to save the conversation?
