Hi Denys,
Am not much user of Kamilio, but am from Telecom background. The reason for
your case is, in side A you have OPUS and in side B already OPUS is
available and since both has the same codec as first priority it will
negotiate itself with same codec and then it will look for other priority.
Remove OPUS from side A and it will automatically go into transcoding mode.

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):

Hello!
Small note.
In case of opus use: codec-transcode-opus (opus is lowercase).
As explained in the readme, the format generally follows the SDP format,
including specifying sample rate and number of channels. As an additional
parameter, the bitrate can be specified for codecs that support it.
Examples:
transcode-speex/32000
transcode-opus/48000/2/64000
Cheers
