    • A system for delivering a caller's phone number to a called subscriber in an Internet telephony system. A calling subscriber (caller) first makes a call to its local server (caller-side server) to request an Internet-based call connection to a remote subscriber (callee). A first transmission unit, disposed in a caller-side local switch, transmits the caller's phone number to the caller-side server through a first control channel. A second transmission unit disposed in the caller-side server then transmits, over the Internet, the caller's phone number to another server (caller-side server) that is local to the callee. The caller's phone number is now available in the callee-side server. A caller number acquisition unit, disposed in the callee-side local switch, makes access to that information by using a second control channel. In this way, the callee-side local switch obtains the phone number of the caller.
    • 用于在因特网电话系统中将呼叫者的电话号码传送给被叫用户的系统。 主叫用户(主叫方)首先呼叫其本地服务器(主叫侧服务器)请求与远程用户(被叫方)进行基于Internet的呼叫连接。 设置在主叫侧本地交换机中的第一传输单元通过第一控制信道将呼叫者的电话号码发送到呼叫者侧服务器。 配置在主叫侧服务器中的第二传送单元然后通过因特网将主叫方的电话号码发送到被叫方本地的另一个服务器(主叫侧服务器)。 主叫方的电话号码现在可以在被叫侧服务器上使用。 设置在被叫侧本地交换机中的呼叫者号码获取单元通过使用第二控制信道来访问该信息。 以这种方式,被叫方本地交换机获得主叫方的电话号码。
