Selects which audio codec compression to use. Selections are G.711
(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 ITM3 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.
Value of the delay limit. The status will change when this limit is ex-
ceeded. The value is measured in milliseconds (ms). This is used to
determine network error.
Value of the loss limit value. The status will change when this limit is
exceeded. The value is measured in percent (%). The range is 00–25
%. This is used to determine network error.
Packet loss estimated base period measured in seconds. The range
is 00–25 seconds. This is used to determine network error.
Limit/loss limit excess count. The range is 0–3. This is used to deter-
mine network error.
Sets maximum value for jitter buffer.
Sets minimum value for jitter buffer.
Determines how DTMF signals are transmitted across the network
(Enabled/Disabled).
Allows auto error correction of fax transmissions across the network
