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
