When a central station uses toll-free 800/888/877 numbers for its receiver
lines, caller ID blocking doesn't matter.  The central station gets the
calling number regardless.  Technically, it's called ANI (automatic number
identification) rather than Caller ID.  It's been that way since 800
numbers were first introduced, the justification being that since the
called party was paying for the call, they had a right to know who was
calling, for billing purposes.
