turns Dial Lock ON
With Dial Lock, you can block certain types of calls such as long distance, local, toll free, operator assisted, directory assistance and 900 numbers.
Dial Lock isn't designed to block specific numbers. However, if the number you want blocked falls into one of the Dial Lock blocked categories, that number will de facto be blocked.
To manage this feature, dial from the line it's installed on, or call 888-(your area code)-8052 from any touch-tone phone.**
