ABSTRACT:
A call charge allocation arrangement is implemented for a business communication system to track those situations in which a toll call is transferred from a first station to a second station. The arrangement tracks such transfers by establishing a first call record at the time the call is placed and establishing a second call record at the time the call is transferred, such that call charges which accrue prior to the transfer are entered in the first call record and call charges which accrue subsequent to the transfer are entered in the second call record.
