调查用户的语音呼叫音频质量Investigate the audio quality of voice calls for a user

如果用户报告其统一消息 (UM) 呼叫的音频质量有问题,可使用"用户呼叫日志"报告来帮助您分析引起这些问题的原因。If a user reports problems with the audio quality of their Unified Messaging (UM) calls, you can use the User Call Logs report to help you understand what's causing the problems.

备注

这些报告中未涵盖的因素也可能会影响呼叫的音频质量。例如,如果 Exchange 服务器遇到较大的内存或 CPU 负载,则即使这些报告表明音频质量较好,用户也可能会报告较差的呼叫质量。The audio quality of a call can be affected by factors that aren't covered in the reports. For example, if your Exchange servers are experiencing a heavy memory or CPU load, users may report poor call quality, even though the reports show excellent audio quality.

使用 EAC 获取启用 UM 的用户的呼叫日志Use the EAC to get call logs for a UM-enabled user

  1. 在 EAC 中,导航到统一消息 > 更多选项更多选项图标 > 用户呼叫日志In the EAC, navigate to Unified Messaging > More optionsMore Options Icon > User call logs.

  2. 单击选择用户,然后选择所需数据的用户。Click Select a user, and then select the user you want data for.

  3. 要获取有关音频质量的更多详细信息报告中的行,请选择的行,然后单击音频质量详细信息。以下信息有:To get more details about the audio quality for a row in the report, select the row and click Audio Quality Details. The following information is available:

    • 日期和时间日期和时间的呼叫,请在所选的用户设置 Outlook Web App 中的时区。DATE AND TIME The date and time of the call, in the time zone that the selected user has set in Outlook Web App.

    • 用户所选的用户。USER The selected user.

    • UM 拨号计划用于呼叫的拨号计划。UM DIAL PLAN The dial plan for the call.

    • UM IP 网关用于呼叫的 UM IP 网关。UM IP GATEWAY The UM IP gateway that was used for the call.

    • 音频编解码器调用过程中使用音频编解码器。AUDIO CODEC The audio codec that was used during the call.

    • NMOS网络意味着平均意见得分 (NMOS) 进行呼叫。NMOS 指示如何良好的音频质量已在调用为范围是从 1 到 5,5 表示极好的数字。NMOS The Network Mean Opinion Score (NMOS) for the call. The NMOS indicates how good the audio quality was on the call as a number on a scale from 1 to 5, with 5 being excellent.

      备注

      呼叫可能的最大 NMOS 取决于使用的音频编解码器。对于通话时间少于 10 秒的非常短的呼叫,NMOS 可能不可用。The maximum NMOS possible for a call depends on the audio codec being used. The NMOS may not be available for very short calls that are less than 10 seconds long.

    • NMOS 下降音频从顶部的值可能正在使用的音频编解码器 NMOS 下降量。例如,如果呼叫的 NMOS 下降值已被 1.2 并 NMOS 报告用于呼叫是 3.3,该特定的呼叫的最大 NMOS 将为 4.5 (1.2 + 3.3)。NMOS DEGRADATION The amount of audio degradation of the NMOS from the top value possible for the audio codec being used. For example, if the NMOS degradation value for a call was 1.2 and the NMOS reported for the call was 3.3, the maximum NMOS for that particular call would be 4.5 (1.2 + 3.3).

    • 抖动在到达的呼叫的数据包的平均变体。JITTER The average variation in the arrival of data packets for the call.

    • 数据包丢失将选择的通话的数据包丢失的平均百分比。数据包丢失的连接的可靠性指示。PACKET LOSS The average percentage of data packet loss for the selected call. Packet loss is an indication of the reliability of the connection.

    • 来回行程平均来回行程分数,以毫秒为单位,所选的呼叫的音频。往返分数度量连接上的延迟。ROUND TRIP The average round trip score, in milliseconds, for audio on the selected call. The round-trip score measures latency on the connection.

    • 突发丢失持续时间将选择的通话过程中出现间歇的数据包丢失平均工期。BURST LOSS DURATION The average duration of packet loss during bursts of losses for the selected call.
