Hey Carsten! How are you? started playing around with sems couple of days
ago.
I was interested on the opus implementation.
noticed that single_codec_in_ok or SingleCodecInOk seems to appear only in
core/AmConfig.cpp and nowhere else
(i'm using master branch)
// single codec in 200 OK
if(cfg.hasParameter("single_codec_in_ok")){
SingleCodecInOK = (cfg.getParameter("single_codec_in_ok") == "yes");
}
another thing is sems uses opus/48000 and not opus/48000/2 which is the new
way of using opus in sdp
some UA don't like opus/48000
