错误"SIP/2.0 488 Not acceptable here"

Question

我设置了User"100"one_answers"200"，我正在尝试使用项目sipml5。

服务器记录了这两个用户，即这个在线Linphone上的用户"100"。

用户"200"在sipml5中记录，但要进行调用，它会显示以下错误：

Answer 1

488应该意味着没有媒体兼容性。

获得488的原因有几个：最常见的是没有常见的编解码器。首先检查您的星号上是否支持并配置了opus。

对于webrtc兼容性，该问题通常与的使用有关

UDP/TLS/RTP/SAVPF

而不是

RTP/SAVPF

ie:webrtc/ietf标准还没有完全定义，而且还在发展中。

您可以在此处检查可能的重复问题/答案：Freeswitch和webRTC：介质被488 拒绝
