    摘要: A call management system is disclosed for choosing the optimum telecommunications carrier for telephone calls made by a user. The system can interface with an existing PBX or with ordinary analog telephone lines. The system intercepts digits dialed by the caller or user and determines an optimum route for the call based on a plurality of parameters. The optimum route includes a particular carrier through which the call is to be placed. The system then dials the prefix for the carrier and subsequently places the destination digits originally dialed by the user onto the telephone line. A data server constructs a carrier selection table optimized for a user's location, calling habits, preferences, personal data, etc. The carrier selection table is downloaded via a communications network to a local computer. In one embodiment, the local computer receives call progress signals and the user's dialed digits from one or more line units. The local computer determines the optimum route utilizing the carrier selection database and passes the calling prefix and destination string to the line unit. In another embodiment, the local computer also performs the functions of the line unit via an attached modem. The local computer, using the modem, intercepts dialing digits, determines the optimum route, places the call, monitors the line for call progress signals and records call start and end times. In the event the modem cannot detect call progress signals, the local computer uses digital signal processing techniques to detect the tones.

    摘要: A least cost routing system comprises at least one telephone dialing unit, at least one least cost router and a database updating unit. The telephone dialing unit dials a telephone number to place a telephone call. Each least cost router has a corresponding routing database of tariffs of telephone service providers and determines, from information in its corresponding routing database, which telephone service provider or providers to utilize to execute the telephone call. The database updating unit electronically updates tariff information into each of the routing databases shortly after updated tariff information is entered therein.

    摘要: A call management system is disclosed that may interface with an existing PBX or may be utilized as a separate unit. In a preferred embodiment, the call management system includes a tariff data server, a local client computer and one or more line units. The tariff data server holds tariff data of service providers and transmits the tariff data to the local client computer via a communications link. The communications link can include the Internet making the tariff data widely available. Each line unit couples a telephone set to the telephone line provided by the LEC. The local client computer maintains a communications link with each line unit. Each line unit can be coupled to more than one LEC, allowing cost optimizations to take into account the LEC in addition to long distance carriers. The line unit intercepts the dialed digits and transmits them to the local client computer. The local client computer determines an optimum route for the call based on various parameters and transmits the complete dialing string back to the line unit which does the actual dialing of the digits. The local client computer maintains a client database of tariffs of telephone service providers and determines, from information in its client database, which telephone service provider or providers to utilize to execute the telephone call. The client database is updated on a periodic basis via, for example, electronic mail or FTP over the Internet. The local client computer also includes a carrier performance monitoring unit and call accounting unit. In another preferred embodiment, the call management system includes a telephone dialing unit and a data server which interfaces to existing PBX equipment.
