Description
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 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.
Set the voice level judged to be silence.
Change value based .30
This entry is ignored if silence compres-
sion is disabled in 84-01-03 with G.711 or
84-01-06 with G.729.
The option selected here determines what
other codec options are applied by priority.
For the system to utilize the G.723 or iLBC
Codecs, program 84-27-02 must be set to
G.723/iLBC.
Define the Auto Gain Control.
Define the DTMF Payload Number.
Determine the DTMF setup used between
the SIP extensions. It is effective when a
terminal call is made through the VoIPDB.
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 assumed 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 packets arriving and the buf-
fer allows this variation to be absorbed.
Set the average G.722 Jitter Buffer.
Set the maximum G.722 Jitter Buffer.
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 assumed 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.
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.
Set the average G.726 Jitter Buffer.
