Description
Selects which audio CODEC compression will be used
and the transmission interval time of VoIP packets gen-
erated by the MGI card. MGI3 card supports
G.729A(8 K), G.729(8 K), G.711(64 K), and
G.723.1(5.3~6.4K).
Enables or disables echo cancellation. This function
removes the echo that is generated by voice reflection
and packet delay.
This parameter determines whether silence suppression
is used. This prevents transmission during the silence
period of a call, and conserves bandwidth when en-
abled.
This option selects input filtering of the DSP. This should
always be set to ENABLE.
This option selects output filtering of the DSP. This
should always be set to ENABLE.
PCM input gain value of DSP. The range is-
31 dB~32 dB(0~63).
This set the quality of PCM voice from the VoIP DSP to
the site. Default is 32(0 dB).
This value selects the voice volume. The range is-
31 dB~31 dB(0~63).
This is a scale value that introduces a intentional
buffer(delay) of the transmission of VoIP packets gener-
ated by the MGI card. This value determines whether
the focus is on packet loss or packet delay.
The range is 00~12.
