User's Manual
Table 53-56: Tone Detection Parameters
Enables the detection of DTMF signaling.

[0] = Disable

[1] = Enable (default)
Enables the detection of MF-R1 signaling.

[0] = Disable (default)

[1] = Enable
Determines the MF-R1 protocol used for detection.

[0] = ITU (default)

[1] = R1.5
Note: For this parameter to take effect, a device reset is
required.
Enables the detection of User Defined Tones signaling,
applicable for Special Information Tone (SIT) detection.

[0] = Disable (default)

[1] = Enable
Enables SIT detection according to the ITU-T recommendation
E.180/Q.35.

[0] = Disable (default)

[1] = Enable
To disconnect IP-to-ISDN calls when a SIT tone is detected,
the following parameters must be configured:

SITDetectorEnable = 1

UserDefinedToneDetectorEnable = 1

ISDNDisconnectOnBusyTone = 1 (applicable for Busy,
Reorder and SIT tones)
Another parameter for handling the SIT tone is
SITQ850Cause, which determines the Q.850 cause value
specified in the SIP 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
