Detect DTMF Tones for Mom's Phones
The battery on my mom's cordless phone is almost gone so it's time for a new one. She has a 1-800 calling card number and code programmed into the phone, but she lost the print information years ago. So, I used this "Detect DTMF Tones" site to decode recordings that I made of the numbers. Now she can get a new phone (or maybe Santa will bring one) and reprogram the calling card numbers for several more years of telephonic bliss.
