(64K), G.723.1 (6.4K), G.729A (8K) and G.729.
Enables or disables echo cancellation (0: disable, 1:enable). This
function removes echo that is generated by voice reflection and
packet delay.
Determines whether silence suppression is used (0: disable, 1: en-
able). This prevents transmission during the silence period of a call.
Selects input filtering of the DSP (0: disable, 1: enable). This should
be set to ON.
Selects output filtering of the DSP (0: disable, 1: enable). This should
be set to ON.
PCM input gain value of DSP. The range is -31dB to 31dB (0–63).
This sets the volume of PCM voice from the VOIP DSP to the site.
Selects the voice volume. The range is -31dB to 31dB (0–63).
This option selects the number of frames the MGI will consolidate in
the packet message. The voice packets are buffered to the set num-
ber and sent as a single packet. The range is 1–12.
Selects the dynamic jitter specific value. Value determines whether
the focus is on packet loss or packet delay. The range is 00–12.
Sets minimum value for jitter buffer.
Sets maximum value for jitter buffer.
Sets additional recovery function for FAX transfer errors when using
T.38 Fax.
Sets maximum number of allowed Internet FAX channels.
Sets whether to transmit the DTMF signal through the voice channel
(INBAND) or through a separate message (OUTBAND).
Defines Type of Service packets.
