Asterisk 沒有播放附加到 IVR 的錄音
我已經設置了一個 IVR 來接聽來電，以允許他們輸入分機或按一個分機進入我們辦公室的響鈴組。唯一的問題是 Asterisk 沒有播放我上傳的 WAV/MP3/GSM 音頻文件。使用預設錄音有效，我不知道為什麼我的不會。我也知道 IVR 可以工作，因為我可以在它停止振鈴後輸入分機。我使用 Elastix 作為 Asterisk 的 GUI。
這是 /var/log/asterisk 中包含的“完整”日誌文件的片段：

在您的輸出中，來自 format_wav.c 模組的錯誤提示輸入不是 wav 文件。檢查您的格式並確保以 Asterisk 期望的格式保存它。
作為一種解決方法，您可以使用開源音頻工具“sox”讓事情變得更簡單：
sox /var/lib/asterisk/sounds/custom/Untitled24.wav -r 8000 -c 1 /var/lib/asterisk/sounds/custom/Untitled24.gsm resample -ql這將創建文件的 GSM 格式，並應使您的擴展邏輯正常工作。
