Description
Related to #529 and w3c/webrtc-pc#637
ORTC mentions "dtmf" as codec.name in various parts of the spec, but there is no "audio/dtmf" MIME type but "audio/telephone-event":
https://www.iana.org/assignments/rtp-parameters/rtp-parameters.xhtml#rtp-parameters-2
Also, ORTC mentions "red" as codec.name, but the IANA table defines:
audio/REDtext/red- (there is not
video/RED)
It seems that being case sensitive will be important so the spec needs some fixes regarding this subject.
You can’t perform that action at this time.
