Tone Detection Parameters

The signal tone detection parameters are described in the table below.

Tone Detection Parameters

Parameter

Description

dtmf-detector-enable

[DTMFDetectorEnable]

Enables the detection of DTMF signaling.

■ [0] = Disable
■ [1] = (Default) Enable

mfr1-detector-enable

[MFR1DetectorEnable]

Enables the detection of MF-R1 signaling.

■ [0] = (Default) Disable
■ [1] = Enable

mf-transport-type

[MFTransportType]

Defines the method for sending MF digits over the network to the remote side.

■ [0] = (Mute) MF digits are erased from the audio stream and are not relayed to the remote side. Instead, silence is sent in the RTP stream.
■ [2] = (Transparent) MF digits are left in the audio stream and MF relay is disabled.
■ [3] = (Default) (RFC 2833 Relay) MF digits are relayed to the remote side using the RFC 2833 Relay syntax.

user-defined-tones-detector-enable

[UserDefinedToneDetectorEnable]

Enables the detection of User Defined Tones signaling, applicable for Special Information Tone (SIT) detection.

■ [0] = (Default) Disable
■ [1] = Enable

sit-detector-enable

[SITDetectorEnable]

Enables SIT detection according to the ITU-T recommendation E.180/Q.35.

■ [0] = (Default) Disable
■ [1] = Enable

To disconnect IP-to-Tel calls when a SIT tone is detected, configure the following parameters:

■ [SITDetectorEnable = 1]
■ [UserDefinedToneDetectorEnable = 1]
■ [DisconnectOnBusyTone = 1] (applicable for busy, reorder, and SIT tones)

Note:

■ For the parameter to take effect, a device restart is required.

udt-detector-frequency-deviation

[UDTDetectorFrequencyDeviation]

Defines the deviation (in Hz) allowed for the detection of each signal frequency.

The valid range is 1 to 50. The default is 50.

Note: For the parameter to take effect, a device restart is required.

cpt-detector-frequency-deviation

[CPTDetectorFrequencyDeviation]

Defines the deviation (in Hz) allowed for the detection of each CPT signal frequency.

The valid range is 1 to 30. The default is 10.

Note: For the parameter to take effect, a device restart is required.
