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
