私有综合服务网络（PISN）是一种专用的通信网络，用于在组织内部提供各种通信服务。PISN可以提供语音、数据和视频通信服务，同时还可以提供各种增值服务，如呼叫等待、呼叫转移、呼叫保持等。PISN的一个重要特点是可以在组织内部建立一个私有的通信网络，使得组织内部的通信更加安全、可靠和高效。

ISO/IEC 20116:2004是一项关于PISN的标准，主要规定了消息中心监控和邮箱识别的补充服务的规范、功能模型和信息流。消息中心监控是指PISN中的消息中心可以监控用户的通信活动，包括接收和发送的消息、呼叫记录等。邮箱识别是指PISN中的消息中心可以识别用户的邮箱地址，以便将消息正确地发送到用户的邮箱中。

ISO/IEC 20116:2004标准规定了消息中心监控和邮箱识别的具体实现方式，包括消息中心监控和邮箱识别的功能模型、信息流和接口定义。该标准还规定了消息中心监控和邮箱识别的相关参数和协议，以确保不同厂家的PISN系统之间可以互相兼容和互操作。

ISO/IEC 20116:2004标准的实施可以提高PISN系统的安全性、可靠性和效率，同时也可以提高用户的通信体验和工作效率。该标准适用于在PISN中提供消息中心监控和邮箱识别服务的系统，包括PISN的消息中心、用户终端和其他相关设备。
