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

[Anthony Minessale]

opus is always cpu intensive.  You are trading more CPU for less bandwdith.
The differing sample rate probably adds more cpu usage because now you are
also transcoding.
You can try opus at 800h@20i but proper support for that will probably only
work on 1. 6 and it still probably will use a lot of CPU.
Its not a problem, its normal.
