Description
There are two types of DTMF transmission: INBAND,
which is industry standard(H.245) type DTMF transport,
and OUTBAND which is a Samsung proprietary
method.
An 8-bit binary value that will be used by external
routers, switches, etc,(that optionally support TOS-bit
prioritization) to identify the transport-priority value of
data packets generated by the MGI card. This value can
be left at the default value(00000) if your network
infrastructure does not support this method of
bandwidth management.
This option selects retry count of Fax-over-IP if errors
are detected. The range is 0~4(0 means no retry).
This option selects the interval time for sending RTCP.

Description
Selects the Audio Codec of an MGI card and specify the
transmission interval time of the VoIP packet.
Enables or disables echo cancellation. This function
removes the echo that is generated by voice reflection
and packet delay.
This option selects the Mode of Dual Filter echo
cancellation. It is improved echo cancellation. This
should be set by Analog Trunk card. If mode is selected
to Disable(Sparse EC), system should be reset.
This optioin controls the non-linear processor.
Set NLP value (0~2).
