If your endpoint supports it, G722@16000h gives a very decent voice quality. SILK also supports 16KHz.here's some information related to codec complexity:

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.On Tue, Oct 6, 2015 at 1:35 PM, Anthony Minessale <anthony.minessale@gmail.com> wrote:typo: opus@8000h@20i--On Tue, Oct 6, 2015 at 3:33 PM, Stanislav Sinyagin <ssinyagin@gmail.com> wrote:OPUS is an expensive codec, so any conversion between OPUS and

would play much of a role in CPU consumption.
