[cisco-voip] g711 sample size in CCM - 10ms or 20ms

[Erick B.]

Thanks for the info.

I did some looking around cisco, but could not find a
answer to my next question.

If a device configured for 10ms sample time places a
call to a phone will the phone self-adjust to 10ms for
that call since the calling device is using 10ms or
will the phone which registers to call manager use
20ms?
