Abstract
A simplified method of encoding information needed to set the NENA 08-001 v2 Result code based on two essential factors that are stored in a data store at runtime. An ESRResponse header is built with two fields created as simple enumerated types: LocationSrc and RoutedOnAlgo. For each emergency call there is one entry in this data store. The first field of the ESRResponse header comprises one of five possible unique values, as does the second field.
