SITQ850Cause, which determines the Q.850 cause value
specified in the Reason header that is included in a 4xx
response when a SIT tone is detected on an IP-to-Tel call.
To disconnect IP-to-CAS calls when a SIT tone is detected,
the following parameters must be configured:

SITDetectorEnable = 1

UserDefinedToneDetectorEnable = 1

DisconnectOnBusyTone = 1 (applicable for Busy, Reorder
and SIT tones)
Notes:

For this parameter to take effect, a device reset is
required.

The IP-to-ISDN call is disconnected on detection of a SIT
tone only in call alert state. If the call is in connected state
the SIT does not disconnect the call. Detection of Busy or
Reorder tones disconnect these calls also in call
connected state.

For IP-to-CAS calls, detection of Busy, Reorder, or SIT
tones disconnect the call in any call state.
Defines the deviation (in Hz) allowed for the detection of each
signal frequency.
The valid range is 1 to 50. The default value is 50.
Note: For this parameter to take effect, a device reset is
required.
Defines the deviation (in Hz) allowed for the detection of each
CPT signal frequency.
The valid range is 1 to 30. The default value is 10.
Note: For this parameter to take effect, a device reset is
required.
Defines when the detection of DTMF events is notified.

[0] = DTMF event is reported at the end of a detected
DTMF digit.

[1] = DTMF event is reported at the start of a detected
DTMF digit (default).
Determines the hook-flash transport type (i.e., method by
which hook-flash is sent and received).

[0] Not Supported = Hook-Flash indication isn't sent
(default).

[1] INFO = Send proprietary INFO message with Hook-
Flash indication.

[4] RFC 2833

[5] INFO (Lucent) = Send proprietary SIP INFO message
with Hook-Flash indication.

[6] INFO (NetCentrex) = Send proprietary SIP INFO
message with Hook-Flash indication. The SIP INFO
message is sent by the device as follows:
