我已经设置了一个 IVR 来接听来电，以便他们输入分机号或按 1 键将其放入我们办公室的振铃组。唯一的问题是 Asterisk 不播放我上传的 WAV/MP3/GSM 音频文件。使用默认录音可以，我不确定为什么我的不行。我也知道 IVR 可以工作，因为我可以在它停止响铃后输入分机号。我正在使用 Elastix 作为 Asterisk 的 GUI。
以下是 /var/log/asterisk 中包含的“完整”日志文件的片段：

答案1
在您的输出中，format_wav.c 模块出现错误，指出输入不是 wav 文件。请检查您的格式，并确保您以 Asterisk 期望的格式保存它。
作为一种解决方法，您可以使用开源音频工具“sox”来让事情变得更容易一些：
sox /var/lib/asterisk/sounds/custom/Untitled24.wav -r 8000 -c 1 /var/lib/asterisk/sounds/custom/Untitled24.gsm resample -ql
这将创建文件的 GSM 格式并使您的扩展逻辑正常工作。
