There's this: http://web.archive.org/web/20060116164248/http://bluebox.sourceforge.net/BlueBox-0.2.tgz ...I can't try it out right now, though.
Historically BlueBox was also used to describe a mechanism used to gain unauthorized access to telecommunications trunk lines. A 2600Hz tone is used to seize a trunk from the telecom switch, and the following keytones are used for call control
700 : 1 : 2 : 4 : 7 : 11 : 900 : + : 3 : 5 : 8 : 12 : 1100 : + : + : 6 : 9 : KP : 1300 : + : + : + : 10 : KP2 : 1500 : + : + : + : + : ST : : 700 : 900 : 1100 : 1300 : 1500 :With the advent of 5ESS, blue-boxing became extremely easy to detect, and therefore has fallen out of favor in the phreaking community.
Does blue boxing still even work? Pretty soon the RedBox? will be just as useless.
