I used to work for the phone company AT&T. If you live in Oklahoma & have SBC/AT&T POTS Landline service, this link advises how to use "CALL TRACE": http://www01.sbc.com/Products_Services/Residential/1,,407--5-3-0,00.html
CALL TRACE can help you take legal action against unwanted callers. After following its instructions, call SBC/AT&T & ask to be xerd to their "CALL TRACE CENTER" where you will be informed of you legal options. They won't give you the person's personal info, etc, but they do give their record of your being called to the authorities. The authorities then have proof of the call having been made & hopefully they'll act on it. I've never had to use it. I hope I don't have to.
Other phone service providers likely have a similar service.
Beware, this service was $6.99 per use when I last worked there a little over 2 years ago. It probably costs more now & the cost isn't noted on the website.
