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

[Oleg Stolyar]

Thanks guys!

Anthony, using your suggestion means that I won't have HD voice, correct?
HD voice is the primary reason I am considering OPUS instead of G.722.

Is there some codec/setting that will let me have HD voice for less CPU and
perhaps more bandwidth?

It's not a must - I can scale up if needed, just wondering.
