Telephone directory ( white pages)?

Quote Subscriber names are generally listed in alphabetical order, together with their postal or street address and telephone number. Every subscriber in the geographical coverage area is usually listed, but subscribers may request the exclusion of their number from the directory, often for a fee. Their number is then said to be "unlisted" (American English), "ex-directory" (British English) or "private" (Australia and New Zealand).





In the case of unlisted numbers, practices as to Caller-ID vary by jurisdiction. Sometimes, the Caller-ID on outbound calls is blank; in other jurisdictions, unlisted numbers still appear, unless the caller dials a blocking code; in still others, the customer may request automatic blocking from the telephone company's service representatives.





In the US, under current rules and practices, mobile phone and Voice over IP listings are not included in telephone directories. Efforts to create cellular directories have met stiff opposition from several fronts, including a significant percentage of subscribers who seek to avoid telemarketers.





In 1991, the U.S. Supreme Court ruled (in Feist v. Rural) that telephone companies do not have a copyright on telephone listings, because copyright protects creativity and not the mere labor of collecting existing information. Within the geographical reach of the Court, the Feist ruling has resulted in the availability of many innovative telephone directory services on CD-ROM and the World Wide Web.


Quote





I know many people who have unlisted in the phone book yet still get telemarketers and if there is 911 hang up how is the police or EMS going to find you?|||telemarketers do not need a directory of phone numbers they collect there numbers from various places, and some even call just random numbers (excluding of course those listed in the do not call registry)





as for how 911 obtains your information, they use ANI to obtain your telephone number and address.. this is diffrent then caller ID which can be easily spoofed or hacked and is not completely reliable...





toll free numbers (800, 866, 877, 888) and toll numbers (900) also use ANI (automatic number identification) to obtain the telephone number of the caller...





if you need verification of this, pick up your phone and dial *67 to block your caller ID information from being sent, wait for dial tone, then dial 1-800-444-4444 and you will hear your phone number read back to you... this number is an ANAC (automated number anouncement circuit) which reads back your ANI information to you...
