Hello!
Small note.
In case of opus use: codec-transcode-opus (opus is lowercase).

Hi,
Quick (and simple) question:
Can someone provide a working RTPengine request, to enable Transcoding?
I know, this is possible, but I thought before looking into deep, how
this should be configured for the rtpengine_offer() command, could someone
provide an example?
It's pretty straight forward.
Example: A offers some SDP to B.
Let's say you think B probably speaks PCMU, so you want to make sure to
offer it, even if A didn't offer it: forward transcoding. Add
`transcode-PCMU`.
Let's say you also know B is allergic to PCMA, so you want to remove it
from the offer to B, but still be able to speak it to A: backward
transcoding. Add `codec-mask-PCMA`.
These two cases are really independent of each other, but can be combined.
Full example with some other options:
rtpengine_offer('ICE=remove rtcp-mux-demux codec-mask-PCMA transcode-PCMU')
Simple!
Cheers
