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 method and system for facilitating calling within an enterprise network upon failure of a landline connection between the enterprise network and an outside call server such as an IP Centrex server. Upon failure of the landline connection, an enterprise router switches over to a backup wireless packet-data link, such as a 3G cellular link for instance. Thus, packet-based call signaling can continue to flow between the enterprise network and the call server so as to continue setting up inside calls between enterprise telephone stations. The backup wireless packet-data link can also be used to carry a limited extent of outside calls, such as emergency calls for instance.

Through determination of whether the account open information of the terminal is consistent with the embezzlement prevention rule of the concurrent call service type or not, wherein the concurrent call service type is determined according to the terminal attribute information and the terminal call right, and through analysis of the set call right and the concurrent call open condition when an account of the terminal is opened, the multichannel embezzlement condition of the terminal can be reduced, and the prevention is carried out actively in advance.

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.

Call features such as available to subscribers of a Centrex telecommunications system are made available to subscribers using internet protocol telephone sets. An internet protocol peripheral unit provides an interface between conventional IP packets utilized by IP telephone sets and the required message and signaling required by a packet line truck unit associated with a switch module of the switch. This permits IP telephone set users to be able to access the applications processor and its associated directory database. Such access is needed to implement certain call features.
