    • Various embodiments are described herein that relate to computer hardware and programs for facilitating international calls between individuals. More specifically, an international call system can route voice traffic between multiple telephone network endpoints. For example, a client application (also referred to as a “client”) may be accessed by a traveler on a mobile phone. The client can be configured to connect to a network-accessible application server, which can communicate with a call processing system that routes voice traffic from the traveler's mobile phone to the mobile phone of a desired contact (and, in some embodiments, vice versa). The international call system described herein makes use of the local providers in each country traversed by the traveler. Consequently, low-cost calling can be enabled in both directions, while predictable reachability is guaranteed as the traveler moves between different local providers.
    • 这里描述了涉及用于促进个人之间的国际呼叫的计算机硬件和程序的各种实施例。 更具体地,国际呼叫系统可以在多个电话网络端点之间路由话音业务。 例如,客户端应用程序(也称为“客户端”)可以由移动电话上的旅行者访问。 可以将客户端配置为连接到网络可访问的应用服务器,该服务器可与呼叫处理系统进行通信,该呼叫处理系统将来自旅行者的移动电话的语音流量路由到期望的联系人的移动电话(并且在一些实施例中,反之亦然) 。 这里描述的国际电话系统利用了旅行者遍历的每个国家的本地提供商。 因此,可以在两个方向实现低成本呼叫,而旅行者在不同的本地提供商之间移动时可以保证可预测的可达性。
