US Patent 7139373 Service delivery instruction processing system and method

A method, system and apparatus for managing delivery service instructions. A method for managing delivery service instructions can include receiving a telephone call from a customer through a PSTN linkage. Identifying information for the customer can be retrieved through a data communications network linkage without identifying said customer using data derived from the telephone call. As such, the retrieved identifying information can be correlated with the telephone call. Finally, access to apply delivery service management instructions received over the PSTN linkage can be authenticated based upon the identifying information.
