Hi everybody,
we've added a Confluence page which focuses on Opus under several points of view, e.g. configuration, installation, development, debugging, negotiation.

You can find it here:
https://freeswitch.org/confluence/display/FREESWITCH/FreeSWITCH+And+The+Opus+Audio+Codec

Please take a look if you're interested and submit your feedback and questions.

Thanks,
Giacomo
