I wish that were true. The latest (issued, March 1991) San Diego Pac Bell directory states: "Most customers can choose to have California 900 and 976 blocked from their telephone line." And the latest (Also issued March, 1991) Western Los Angeles GTE directory states: "This feature, if available in your area, allows you to block the direct dial of 976 numbers within California and all 900 numbers from your telephone. If you chose this service, you will be unable to place calls to all 976 numbers within California and all 900 numbers." Note that Pac Bell limits blocking to "most customers" and "California 976 and 900" (whatever that means) and GTE has a similar restriction for 976 numbers. If the telcos really wanted to provide complete blocking, they obviously could! Besides, next year the telcos will probably invent 901 numbers, then 902 numbers. David G.
