I am working on a phone line alarm receiver and I have been asked to handle DNIS (Dialed Number Identification Service). I am looking for any documentation or advice concerning that service for Canada and USA...
Our line interface includes a DTMF decoder and a FSK caller ID receiving chip.

DNIS is (I think) when you have many telephone numbers leading to one call centre. For a fee, your telephone company will send you a string of digits (in DTMF) so that your equipment will know what number was actually called so that your systems can respond according. I know nothing more.
