Title: Call transfer and conference with separate billing records per leg

Abstract: A system efficiently transfers a telephone call from a caller terminal for a desired class of service and produces separate billing records for each leg of the call. The system includes a network level server connected to a network level switch. The network switch receives the call from the caller terminal and transmits information about the call to the network server. The network server produces a first directory number for the call based on the call information from the network switch. The network switch receives the first directory number from the network server, establishes a first connection from the caller terminal to a first terminal identified by the call using the first directory number, and creates a first billing record for the first connection. The network server receives a request to transfer the call to a second terminal from the first terminal and produces a second directory number for the call transfer. The network switch receives the second directory number from the network server, establishes a second connection to the second terminal using the second directory number, and creates a second billing record for the second connection.
