Question on G722, trying to see if the quality of basic g.722 is much better than the standard g729 or g711.
The quality of G.711 is considerably better than G.729. The quality of G.722 is *massively* better than G.711. Why you can even spell things out, and be understood, without going "no F for Freddy, not S for stuff" all the time. :-)
Looking at wiki docs. “G722 - G722 16kHz using default 20ms ptime. (multiples of 10)”
However, when I connect to freeswitch using blink client I see G722/8000? I thought this would be 16000. I know when I connect using speex wb, it shows 16000.

Shouldn’t this be 16000?
Thanks
