Abstract: A system for providing automated directory look-up over multiple switching systems in a network. Multiple switching systems are connected in a network. When a first switching system receives a request for a directory look-up, the first switching system generates a message requesting a directory look-up on each of the other switching systems. The messages is then transmitted to each of the other switching systems. The other switching systems receive the request and perform a look-up for matches to an input string. Response messages containing all of the matches are then transmitted back to the first switching systems. It is then determined whether a match for the desired name was found and the call is completed.
