value to the highest setting that the device allows. The range is
20 to 200 ms and is dependent on the codec. Changing this
value can cause the automatic adjustment of the other settings
for this codec. For more information, see Converging the Data
Network with VoIP Fundamentals (NN43001-260).
d. Voice playout (jitter buffer) maximum delay: The maximum
delay has a range of 60 to 500 ms and is dependent on the
codec. Changing this value can cause the automatic adjustment
of the other settings for this codec.
e. VAD: Select this check box to enable Voice Activity Detection.
Because CS 1000 Release 5.0 does not support VAD for
G723.1codec, Element Manager does not support configuration
of VAD for G723.1.
Repeat step 5 for each of the selected codecs.
