[Freeswitch-users] Conference vs codec sample rate and CPU

[Brian West]

Auto only sets the conference rate to the rate of the first person to join,
and yes you'll see resampling taking place when you use OPUS since its
always opened at 48000.

You can force the sample/capture rates in opus.conf.xml in master.
