    Hello to all,

    Is there some way to set up 3cx so that it automatically blocks all numbers -- except those in a whitelist?

    I know this sounds extreme, but we spend waaaay too much time answering bogus calls!

    Make an inbound CID rule with a mask of * with a destination of END CALL, then make an inbound CID rule for each number that is allowed and put it ahead of the * rule.

    If you need this to be database driven, voiptools has a caller-id router add-on that can read from a sql database. You can have it route the matched numbers to one destination and anything unmatched to an end call route.
