And there's no any errors in RTPEngine log.

I also found this https://github.com/OpenSIPS/opensips/issues/1288#issuecomment-367293070

And tried as Razvan adviced:

# i know that B side talks PCMU only, so i configre it
rtpengine_offer("RTP/AVP replace-origin replace-session-connection ICE=remove transcode-PCMU");


In this case - a little bit better - the call is not dropped, and I see how OpenSIPS/RTPEngine
changes the codecs, and even see RTP, but going to one side only, but in different codecs.

But still no sound in any direction  :D
