Description
Set the average value of the G.723
Jitter Buffer.
Set the maximum value of the G.
723 Jitter Buffer.
Set the mode of the Jitter Buffer.
1 = Size set to the fixed amount for
the codec.
2 = The minimum/maximum range
for the codec is used.
3 = The minimum/maximum range
for the codec is used and adjusts at
any time, regardless of silence.
Set the voice level judged to be si-
lence. Change value based .30
This entry is ignored if silence com-
pression is disabled in 84-01-03 with
G.711 or 84-01-06 with G.729.
The option selected here deter-
mines what other codec options are
applied by priority.
Define the Auto Gain Control.
Define the DTMF Payload Number.
Determine the DTMF setup.
Maximum number of G.722 Audio
Frames. G.722 assumes the audio
signal made by a specimen by 16
kHz and the frame of 10 ms is as-
sumed to be a unit to 64 kbps by the
encoding compressed method.
Set the minimum value of the Jitter
Buffer of G.722 is set. Jitter is the
variation in the time between pack-
ets arriving and the buffer allows
this variation to be absorbed.
Set the average G.722 Jitter Buffer.
Set the maximum G.722 Jitter Buf-
fer.
Maximum number of G.726 Audio
Frames. G.726 assumes the audio
signal made by a specimen by 16
kHz and the frame of 10 ms is as-
sumed to be a unit to 32 kbps by the
encoding compressed method.
Select whether to compress silence
with G.726. When there is silence,
the RTP packet is not sent.
