[Freeswitch-users] G722 16k or 8k?

[Stephen Dame]

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
