Location relevant directory assistance |
摘要 |
A method for location relevant directory assistance through a PSTN is provided. The method can include connecting a calling party with a called party through a switch in a PSTN, receiving a directory assistance request from the calling party over the PSTN, and querying a database disposed within the PSTN to retrieve caller identification for the calling party. The method can further include retrieving from over a data communications network separate from the PSTN a call address in response to the querying of the database for the calling party from the database disposed within the PSTN. Location relevant directory information can be identified from a database that is external to the PSTN based upon the retrieved call address. Subsequently, the directory assistance request can be responded to using the identified location relevant directory information.
