What's the name of the style of telephone rings in 24, and where can I find an audio file of a ring that isn't from the show?

My dad had that same system in his office, and I want to use the ring as my ringtone. I realize, however, that many 24 fans have the distinctive CTU ring already, and since I don’t watch the show, I don’t want that ringtone—I mean, that would be just silly.

For super-duper bonus points, the specific tone I’m looking for is middle… high low high (sol… do do do if you know solfeggi)
