[TELECOM Digest Editor's Note: I tried it, it is a national service, handled as much as possible by interactive voice recordings. But their voice recognition software does not seem to be very good. After three or four attempts to find out what I wanted "a radio station, KOSN in Stillwater, OK" it gave up and transferred me to an operator. PAT]
