seven,<br><br>of course, codec negotiation depends on the order of codecs in the *_codec_prefs variables. but, the opposite end has also it&#39;s own codecs prefs, too. fs can accept the other end&#39;s prefs (inbound_codec_negotiation=generous) or imposes it&#39;s own prefs (=greedy). you must include the codec in the *_codec_prefs to activate it. is this correct?<br>
