使用会话发起协议（SIP）进行分布式呼叫监控/记录的系统和方法

System and method for distributed call monitoring/recording using the session initiation protocol (SIP)
Abstract:
The system and method described herein allows for full monitoring and recording of SIP calls by using standard SIP messages. During the call set up between a first SIP device and a second SIP device, information is derived from a first SIP INVITE message from a first SIP device. Information is then derived from a response message from the second SIP device.The monitor/recorder receives one or more SIP INVITE messages to set up a first media stream from the first SIP device and a second media stream from the second SIP device to the monitor/recorder. The monitor/recorder receives the first and/or second media stream. The monitor/recorder then records the first and/or second media stream. In addition, the system and method provide for recording on demand, required recording, and pause-and-resume recording of SIP calls.
Abstract(Chinese):

这里描述的系统和方法允许通过使用标准SIP消息来完全监视和记录SIP呼叫。 在第一SIP设备和第二SIP设备之间的呼叫建立期间，从第一SIP设备的第一SIP INVITE消息导出信息。 然后从第二SIP设备的响应消息导出信息。 监视器/记录器接收一个或多个SIP INVITE消息以建立来自第一SIP设备的第一媒体流以及从第二SIP设备到监视/记录器的第二媒体流。 监视器/记录器接收第一和/或第二媒体流。 监视器/记录器然后记录第一和/或第二媒体流。 另外，该系统和方法提供按需记录，所需记录以及SIP呼叫的暂停和恢复记录。
