606 Not Acceptable
The user's agent was contacted successfully but some aspects of the session description (SDP) are not acceptable. Unlike 488, this is a global failure — no other server can satisfy this request.
当您看到此代码时
When the callee definitively cannot accept any of the offered media types or codecs. Different from 488 which is location-specific.
如何修复
Check the Warning header or response body for which session parameters are unacceptable. Modify the SDP offer to use compatible codecs and media types.
