Just posting this to document the end result. The following line to
pass the transcoding parameters I wanted directly to the RTPEngine daemon
worked for me:
transcode-opus/48000/2/32000//stereo--0;useinbandfec--1;maxplaybackrate--16000;sprop-maxcapturerate--16000
NB - The '--' part means '='
No worries

Ah! Thanks Răzvan and Johan. I was thinking that the options described in
the OpenSIPS RTPEngine module documentation were the only ones
available, but I missed the key phrase...
*When passing an option that OpenSIPS is not aware of, it will be

I think the proper way to do it is
`transcode-opus/48000/2/32000//maxplaybackrate--48000;stereo--0;useinbandfec--1;maxaveragebitrate--32000`
Anyway, as Johan suggests, follow the rtpengine documentation, you will
find more info there.

Follow the rtpengine documentation. The necessary flags are given there,
just pass them in an avp to rtpengine_offer or answer

No. I'm not sure how I would specify this in the opensips.cfg
rtpengine_offer parameters. From the documentation
Hi, Mark!
OpenSIPS passes the commands to RTPengine as you supply them, so in
theory this should be supported. Did you try to set this up? Can you
provide any logs about this?

Hi all,
I'm using RTPEngine for transcoding between Opus and PCMU. According to the
RTPEngine documentation (https://github.com/sipwise/rtpengine), it can
accept formatting parameters for CODECs that support them. For instance,
Opus allows you to change the maxaveragebitrate. However, in the
