Abstract
A call billing method and apparatus establishes an ISDN connection between the network and a called location which enables the called location to specify call billing information to the network, via the ISDN connection, on a call-by-call basis. The method provides the called party real time access to network rate tables to specify call billing parameters needed to generate a separate billing record for each call made to the called location. Other features enable the caller or called location to provide various types of information for call billing purposes.
