Abstract
A system and method for validating pieces of information associated with a telephone call. An operator console receives a call having one or more pieces of information that are to be validated. The operator console sends a validation request to a validation system. The validation system includes a database that stores instructions that define at least a part of a validation procedure corresponding to the validation request. The validation system returns a validation response to the operator console which subsequently indicates that the telephone call can be completed.
