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.

摘要翻译： 公开了可以与现有PBX接口或可以用作单独单元的呼叫管理系统。 在优选实施例中，呼叫管理系统包括资费数据服务器，本地客户端计算机和一个或多个线路单元。 资费数据服务器保存服务提供商的费率数据，并通过通信链路将资费数据发送到本地客户端计算机。 通信链路可以包括使得资费数据广泛可用的因特网。 每个线路单元将电话机耦合到由LEC提供的电话线路。 本地客户端计算机与每个线路单元保持通信链路。 每个线路单元可以耦合到多个LEC，允许成本优化考虑到长距离运营商以外的LEC。 线路单元拦截拨号数字并将其发送到本地客户端计算机。 本地客户端计算机基于各种参数确定呼叫的最佳路由，并将完整的拨号串发送回执行数字的实际拨号的线路单元。 本地客户端计算机维护电话服务提供商的资费的客户端数据库，并从其客户数据库中的信息确定哪个电话服务提供商或提供商用于执行电话呼叫。 客户端数据库通过例如电子邮件或通过因特网的FTP定期更新。 本地客户端计算机还包括运营商绩效监控单元和呼叫计费单元。 在另一个优选实施例中，呼叫管理系统包括与现有PBX设备接口的电话拨号单元和数据服务器。
