Checked before, not after
The suppression file you maintain is checked before the number is dialed, not after the connect. That sounds obvious until you look at how many floors scrub at list load and then run the same list for three weeks.
Written back immediately
When somebody asks not to be called again, the bot writes it to your suppression file there and then. It does not wait for a wrap-up, and it does not depend on somebody remembering at the end of a shift.
Across campaigns, not just this one
A request to stop calling is a request to stop calling, not a request to stop calling about Medicare. Suppression that only applies to the campaign the person was on is the single most common cause of a complaint that a floor thought it had already handled.
