Input Data
0 ~ 300 ms Set the maximum value of the G.723 Jitter
Buffer.
1 = static Set the mode of the Jitter Buffer.
3 = adaptive immediately 1 = Size set to the fixed amount for the co-
dec.
2 = The minimum/maximum range for the
codec is used.
3 = The minimum/maximum range for the
codec is used and adjust at any time, re-
gardless of silence.
1 ~ 30 Set the voice level judged to be silence.
(self-adjustment and - 19 Change value based .30
dB ~ + 10 dB) This entry is ignored if silence compres-
1 = - 19 dB (- 49 dBm) sion is disabled in 84-01-03 with G.711 or
: 84-01-06 with G.729.
20 = 0 dB (- 30 dBm)
:
29 = 9 dBm (- 21 dBm)
30 = 10 dBm (- 20 dBm)
The option selected here determines what
1 = G.723 PT other codec options are applied by priority.
2 = G.729 PT For the system to utilize the G.723 or iLBC
3 = G.722 Codecs, program 84-27-02 must be set to
4 = G.726 G.723/iLBC.
5 = iLBC
0 ~ 5 Define the Auto Gain Control.
96 ~ 127 Define the DTMF Payload Number.
0 = Disable Determine the DTMF setup used between
1 = RFC2833 the SIP extensions. It is effective when a
terminal call is made through the VoIPDB.
1 = 10 ms Maximum number of G.722 Audio Frames.
2 = 20 ms G.722 assumes the audio signal made by
3 = 30 ms a specimen by 16 kHz and the frame of 10
4 = 40 ms ms is assumed to be a unit to 64 kbps by
the encoding compressed method.
0 ~ 255 ms Set the minimum value of the Jitter Buffer
of G.722 is set. Jitter is the variation in the
time between packets arriving and the buf-
fer allows this variation to be absorbed.
0 ~ 255 ms Set the average G.722 Jitter Buffer.
0 ~ 255 ms Set the maximum G.722 Jitter Buffer.
1 = 10 ms Maximum number of G.726 Audio Frames.
2 = 20 ms G.726 assumes the audio signal made by
3 = 30 ms a specimen by 16 kHz and the frame of 10
4 = 40 ms ms is assumed to be a unit to 32 kbps by
the encoding compressed method.
0 = Disable Select whether to compress silence with
1 = Enable G.726. When there is silence, the RTP
packet is not sent.
0 ~ 255 ms Set the minimum value of the Jitter Buffer
of G.726 is set. Jitter is the variation in the
time between packets arriving and the buf-
fer allows this variation to be absorbed.
0 ~ 255 ms Set the average G.726 Jitter Buffer.
