    • A system for billing Internet protocol (IP) telephony, or other telecommunication calls transmitted over data packet networks, is provided. Calls may be routed over networks of different types, e.g., H.323 networks or IP voice networks. Different types of network devices, e.g., call managers, switches, or gateways, may transmit legs within a call. Each device type typically generates call records that have data fields unique to that device. In order to generate a single billing record for each call, call records are standardized and then matched with call records from other devices. Key fields within call records that may be matched include: call connect timestamps, signal start timestamps, calling party identifiers, called party identifiers, or network device identifiers. Timestamps within call records may be synchronized from a common time server.
    • 提供了用于计费互联网协议(IP)电话或通过数据分组网络发送的其他电信呼叫的系统。 呼叫可以通过不同类型的网络进行路由,例如H.323网络或IP语音网络。 不同类型的网络设备,例如呼叫管理器,交换机或网关,可以在呼叫内发送支路。 每种设备类型通常会生成具有该设备唯一的数据字段的呼叫记录。 为了为每个呼叫生成单个记帐记录,呼叫记录被标准化,然后与来自其他设备的呼叫记录进行匹配。 可能匹配的呼叫记录中的关键字段包括:呼叫连接时间戳,信号开始时间戳,主叫方标识符,被叫方标识符或网络设备标识符。 呼叫记录中的时间戳可以从公共时间服务器同步。
