On the practical side of things, how would she record the phone call? I assume that Jodi and Travis were using cell phones for the free long distance. Or at least whoever initiated the call placed it on their cell phone. What kind of recording device would you use? Your home answering machine (with a beep every 10 seconds?!) Will the cell phone itself do it? If so, I would assume that it would require one of these newer mega microSD cards to hold the conversation. The large capacity microSD cards (16 GB, 32 GB) were not available in 2007. Please don't tell me she was doing it on a cassette deck with a microphone?
