> While debugging the [ToC byte|https://tools.ietf.org/html/rfc6716#section-3.1] in the RTP media stream of the audio codec Opus Codec, I noticed, the Digium/Sangoma module sends Mediumband although the caller stated to support Wideband in its SDP. I overwrote this via the configuration file {{codecs.conf}} but the result was not good audio either. Then, I noticed that the documentation states ([Blog|https://www.asterisk.org/?p=1243], [Wiki|https://wiki.asterisk.org/wiki/display/AST/Codec+Opus]):
> * {{max_playback_rate=16000}} to be Mediumband (mb) not Wideband (wb),
> * {{max_playback_rate=24000}} to be Wideband (wb) not Super Wideband (swb).
> Because the module is closed source, I can only guess that is the cause for my seen issue. In [RFC 7587|https://tools.ietf.org/html/rfc7587#section-2], I read table 1 differently. If we disagree on that, who is asking upstream in the [Opus mailing list|https://lists.xiph.org/mailman/listinfo/opus]?
