Origin
This idiom comes from poker. In poker, players bet on who has the best hand. In relation to poker, Bluffing involves betting on a hand that one does not believe to be the best, in the hopes that an opponent who has a better hand folds or withdraws from the game. Calling relates to matching a bet with an equivalent amount.
A poker player who wishes to call a bluff would bet an equal amount to the bluffing player. When the cards are revealed, the player with the best hand wins the entire pot (all the money put up by the players so far).
The term, just like poker, is American in origin and dates back to the 1800s. By the late nineteenth century, its use had made its way to the idiomatic nature we see today. "Where shall we be when that bluff is called" was an entry in the Congressional Record in March 1896, which indicates that the idiom was in use by this time.
