Parameter
Mediant 1000 Gateway & E-SBC | User's Manual
Description
■ [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 the 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
Digital interfaces: 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)
Digital interfaces: 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-Tel 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)
Note:
■ For the 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.
