That's the Jackulator 4000. It has everything needed to make great prank calls. When I made calls I actually only used the order specific (food, hotel, ...) lines from there, and do the rest on the Jackbox (swf item on the bottom of the website), especially because you can use the keyboard on that to re-open sections. I find that to be very convenient.
(I actually thought I had a backup of the Jack4000 on my HDD. Then it comes to me that last year one of my fucking RAID 1s crashed and couldn't be recreated. So gone is a lot of stuff, including my own soundboards that I used for my calls. NEVER rely on RAID for data security, children.)
