>                 Key: ASTERISK-30358
>                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30358
>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_sip/CodecHandling, Codecs/codec_opus
>    Affects Versions: 18.15.0
>            Reporter: Ruben Iniguez
>            Severity: Major
>
> Opus configuration options in codecs.conf seem not to take effect.Example of this follows below:
> For the config in codecs.conf:
> [myopus]
> type=opus
> max_playback_rate=8000
> The SDP in 200 OK provided by Asterisk is:
> v=0
> o=- 1035043469 4 IN IP4 10.10.10.121
> s=Asterisk
> c=IN IP4 10.10.10.121
> t=0 0
> m=audio 23326 RTP/AVP 111 126
> a=rtpmap:111 opus/48000/2
> a=fmtp:111 useinbandfec=1
> a=rtpmap:126 telephone-event/8000
> a=fmtp:126 0-16
> a=ptime:20
> a=maxptime:20
> a=sendrecv
> So it is missing maxplaybackrate parameter in SDP.
> I haven't made exhustive checkings but so far I found only bitrate parameter (maxaveragebitrate on SDP) is configurable.
> I found ASTERISK-26901 is related to this. However I opened a new case since that one seems unattended.
