Why "dial 9 for outside line" may go away

Typically, to dial out from an office line you hit 9 first. BB's saint of author services at Federated Media, Mugs Buckley, tells me that's changing for a very interesting reason. Mugs writes:

FM used an 8 and the other office I'm in just changed their system to a 7 due to the San Mateo police department getting all upset (and I don't blame them) about how many false calls there are to their system.
