A menu routing service routes calls made to a customer's toll-free number according to customized routing instructions. A service provider establishes service parameters, which include the toll-free number and a restriction associated with at least one of the customer and the service provider. To customize call routing, a web server receives instructions from the customer to associate the toll-free number with a terminating number, such as a directory number or switch ID and trunk group numbers. When the restriction prohibits the association, the web server determines whether the service parameters further include an override indicator associated with the customer that overrides the restriction. The toll-free number is associated with the terminating number when service parameters include the override indicator. The override indicator may be an affiliate indicator, which enables the customer to terminate inter-LATA calls in a region in which the service provided is prohibited from providing long distance service.
