A method and system include screening and routing telephone calls, generating calling data reports and discounting billing for a customer's wide area centrex / PBX network, which includes an abbreviated dialing plan. A service control point (SCP) determines whether to block an outgoing call based on stored blocking tables and a privilege class of the calling station. The SCP determines whether to route the call through a private trunk group from a host switch to a private facility, and through an alternative trunk group when the private trunk group is unavailable. The SCP determines whether the call is eligible for discounted billing and generates a billing record, which is modified by a service switching point to indicate the discount. The SCP also samples calling data from service switching points and transmits the sampled data to a front end processor for formatting into station message detail recording (SMDR) data.

A computerized telephony call center for serving a customer base has a central switch connected to a plurality of telephones at operator workstations and adapted to route calls to individual ones of the telephones, and also connected to a public switched telephone network, and a first processor connected to the central switch by a high-speed data link and to the telephone network by a digital network connection. The first processor is adapted to monitor transactional activity of the central switch, to process the activity information according to selected routines in the processor, and to communicate processed information to a second processor over the digital network connection. The digital network connection may be a TCP\IP connection. In a preferred embodiment the first processor is connected by a local area network (LAN) to network interfaces including a video display unit (VDU) and input apparatus proximate individual ones of the plurality of telephones connected to the central switch. In some embodiments the LAN is also connected to a data server running an instance of a database. In other embodiments the call center, and other similar call centers are all part of a call routing system wherein calls are routed from Service Control Points to call centers over telephone lines, and data is routed to the call centers over a separate digital network connection between processors coupled to the Service Control Points and to the call center central switches. In various embodiments aspects of the invention apply to Internet protocol network telephony (IPNT) calls as well as to conventional telephony calls.

A method and system for generating customer reports based on station message detail recording (SMDR) data includes a service control point (SCP) in a public switched telecommunications network (PSTN). The service control point samples calling data from multiple service switching points for calls originating from a private customer network, including centrex and PBX systems. The service control point interfaces with a front end processor and transmits the calling data. The front end processor formats the calling data into SMDR data, which is transmitted to a host central processing unit. The host generates reports regarding the SMDR calling data, the reports being accessible by a customer via a connection to a private customer network.
