Abstract
A call control apparatus for a pay phone includes a reading unit, a calculating unit, and a call enable unit. The reading unit reads out value information of an inserted card. The calculating unit calculates a call time corresponding to a ratio of the value information to a unit call fee when the value information read out by the reading unit does not reach the unit call fee. The call enable unit allows a call service by the call time calculated by the calculating unit.
