調查組織中的語音通話的音訊品質Investigate the audio quality of voice calls in your organization

如果您的組織發生 Unified Messaging (UM) 呼叫與語音郵件訊息的音訊品質問題,請使用呼叫統計資料報告以協助您瞭解問題的肇因。If your organization is experiencing problems with the audio quality of Unified Messaging (UM) calls and voice mail messages, use the Call Statistics report to help you understand what's causing the problems.

注意

不涵蓋報告中的因素會受通話的音訊品質。例如,如果您的 Exchange 伺服器負載大量記憶體或 CPU 負載量,使用者可能會報告收訊不良通話品質即使報告顯示實用的音訊品質。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 load or CPU load, users may report poor call quality, even though the reports show excellent audio quality.

使用 EAC 以取得您組織的音訊品質統計資料Use the EAC to get audio quality statistics for your organization

  1. 在 EAC 中,瀏覽至 整合通訊 > 更多選項![更多選項] 圖示 > 呼叫統計資料In the EAC, navigate to Unified messaging > More optionsMore Options Icon > Call statistics.

  2. 選擇要包含在報表中的呼叫統計資料。報表會自動更新當您選取任何下列的選項。Choose the call statistics to include in the report. The report automatically updates as you select any of the following options.

    • 顯示選擇何種類型的檢視通話統計資料:Show Choose what type of call statistics to view:

    • 每日 (90 天) 選取 [每日可以在過去 90 天中看見的所有呼叫的詳細資訊。Daily (90 days) Select Daily to see details for all calls in the past 90 days.

    • 每月 (12 個月) 選取 [每月的最後一個的 12 個月內的每月查看之呼叫的摘要。Monthly (12 months) Select Monthly to see a summary of calls by month for the last 12 months.

    • 所有選取 [全部查看合併的 UM 開始處理通話後收到的所有呼叫統計資料。All Select All to see the combined statistics for all calls received since UM started handling calls.

    • UM 撥號對應表如果您想要將以唯一的電話報表中的資料限制在特定的 UM 撥號對應、 選取的撥號對應表。UM dial plan If you want to limit the data in the report to only calls in a specific UM dial plan, select that dial plan.

    • UM IP 閘道器如果您想要限制只在特定的 UM IP 閘道呼叫報表中的資料,請選取該 UM IP 閘道器。如果您先選取 UM 撥號對應表,只選取 UM 撥號對應表相關聯的 UM IP 閘道都可在清單中。UM IP gateway If you want to limit the data in the report to only calls in a specific UM IP gateway, select that UM IP gateway. If you select a UM dial plan first, only the UM IP gateways associated with the selected UM dial plan are available in the list.

  3. 若要取得音訊品質的更多詳細報告中的列,選取的資料列,按一下 [音訊品質詳細資料。是下列資訊: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:

    • 日期及時間UTC 的日期與時間已擷取通話統計資料。DATE AND TIME The UTC date and time that the call statistics were captured.

    • UM 撥號對應表撥號對應表的統計資料中包含的通話。UM DIAL PLAN The dial plan for the calls included in the statistics.

    • UM IP 閘道萬一併入統計資料之通話的 UM IP 閘道。UM IP GATEWAY The UM IP gateway that took the calls included in the statistics.

    • NMOS網路平均意見分數 (NMOS) 的通話。NMOS 指出如何良好的音訊品質有關該通話為介於 1 到 5,具有正在實用的 5 規模上的號碼。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.

      注意

      可能的通話的最大 NMOS 是取決於所使用的音訊轉碼器。NMOS 可能無法極短通話所少於 10 秒的 long。The maximum NMOS possible for a call is dependent on the audio codec being used. The NMOS may not be available for very short calls that are less than 10 seconds long.

    • NMOS 效能下降從上方的值可能正在使用的音訊轉碼器的 NMOS 的音訊降低量。例如,如果來電的 NMOS 效能下降值是 1.2 NMOS 報告通話所 3.3,該特定的通話的最大的 NMOS 就是 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).

    • 抖動通話的資料封包抵達中平均的變化。JITTER The average variation in the arrival of data packets for the call.

    • 封包遺失資料封包遺失所選通話的平均百分比。封包遺失是可靠性的相對值的連線。PACKET LOSS The average percentage of data packet loss for the selected call. Packet loss is an indication of the reliability of the connection.

    • 來回平均來回分數,選取通話的音訊 (毫秒)。來回分數措施連接上的延遲。ROUND TRIP The average round trip score, in milliseconds, for audio on the selected call. The round-trip score measures latency on the connection.

    • 高載遺失持續時間平均持續時間的封包遺失量激增時的所選的通話。BURST LOSS DURATION The average duration of packet loss during bursts of losses for the selected call.

    • 號碼的範例取樣的計算平均值的通話數目。NUMBER OF SAMPLES The number of calls that were sampled to calculate the averages.
