A call routing system stores includes a processor that retrieves account information from a storage and identifies a previously provided telecommunications service that was provided to the party based on the account information. The processor restricts access to telecommunications services based on the identified previously provided telecommunications service and determines additional telecommunications services, distinct from the previously provided telecommunications service, desired by the party. The processor receives a selection from the party of the additional telecommunications services and processes a service request from the party based upon the selection by the party. A routing element suppresses routing of the call to a service center that provides the previously provided telecommunications service that was provided to the party, and routes the call to a service center that provides the additional telecommunications services selected by the party.
