ABSTRACT:
A method and apparatus determine a caller's eligibility to enter a lottery, determine whether the caller has won the lottery and advises the caller of the winning status while communication services are provided between the caller and a called party. Thus, the caller can enter, win and be advised of winning status while communication, e.g. telephone voice communication, takes place between the caller and a called party. The caller need not dial a specific telephone number to enter the lottery. Instead, communication with any desired called party can take place.
