SIT stands for "Standard Intercept Tone," and is the tone you hear just before "We're sorry, the number you have reached has been disconnected or is no longer in service." Telemarketing (and bill-collecting) autodialers use SIT to speed things along as they "spam" through hundreds of phone numbers at a time. If they hear SIT, they don't wait for more; they drop the line immediately and head for greener pastures. Of course, not all autodialers are sensitive to SIT, but some are. The only problem with using SIT is that some people might think they've misdialed when they call you, including folks you want to hear from.
