Beat you to it. What *I* need are frequencies.... The complete description of SIT (Special Information Tones) including frequencies, cadence, and tone duration, with listings concerning the different "call failure" categories, is available from: * Bellcore * The Public Library * Your local LEC (DID customers are required to have them for vacant lines) * Your state PUC * Half the readers of the Digest In short, possession of this information is not a Federal crime. I'd post is all here, but someone borrowed my big yellow Bellcore book and didn't return it. (Or did the person I was borrowing it from take it back? I can't remember.) Call Pac*Bell and ask for their IXC information package. I did. It is highly informative. John Higdon | P. O. Box 7648 | +1 408 723 1395 john@bovine.ati.com | San Jose, CA 95150 | M o o ! [Moderator's Note: But one thing puzzles me: What's to prevent anyone or everyone from answering *all* their phone calls that way? In other words, when you go off hook to answer a call, 'da da dee', then begin your conversation. What prevents anyone from playing games like this to provide the essence of a 'toll-free' number to callers? PT]
