Question on G722, trying to see if the quality of basic g.722 is much
better than the standard g729 or g711.
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
