[SR-Users] RTPengine - Transcoding example available?

[Denys Pozniak]

Hello!

Please explain how to achive next:

Side A supports:
OPUS
PCMA

Side B supports:
OPUS
PCMA
PCMU

I need to transcode in direction A->B from PCMA to OPUS?
So should be like this:
A(PCMA) -> (PCMA)Rtpengine(OPUS)->B(OPUS)

I configured like this:
rtpengine_offer("codec-mask-PCMA codec-transcode-opus");
rtpengine_answer("codec-mask-opus codec-transcode-PCMA");

But leg from Rtpengine to A has wrong codec (OPUS):
