Abstract
A billing method and system include discounting a customer's billing for telephone calls completed in a wide area centrex/PBX network, which includes an abbreviated dialing plan. A service control point (SCP) determines a call type code based upon a calling station and a called station of a telephone call. The SCP determines whether the call type code is eligible for discounted billing. When the call type code is eligible, the SCP generates a unique billing record that is forwarded to a service switching point (SSP). The SSP receives the forwarded unique billing record and modifies the billing record to indicate that a discount should be applied to the billing for the call when the call is completed. When the SSP does not receive the unique billing record, it creates a normal billing record.
