Thanks for the link, I looked at the commit and then at
https://tools.ietf.org/html/rfc7587 and yeah under paragraph 7 it has:
{{{
The media subtype ("opus") goes in SDP "a=rtpmap" as the encoding
name. The RTP clock rate in "a=rtpmap" MUST be 48000, and the
number of channels MUST be 2.
}}}
so the comment is correct, will close the issue.
