[DTMFInterDigitInterval]
Version 7.0
the DSPTemplates parameter is configured.

For a list of supported DSP templates, see SBC and DSP
Channel Capacity on page 1061.
Determines the DSP template used by the device. Each DSP
template supports specific coders, channel capacity, and features.
The default is DSP Template 0.
You can load different DSP templates to digital modules using the
syntax DSPVersionTemplateNumber=xy
where:

y = 0 to 5 for DSP templates of digital modules
Notes:

For the parameter to take effect, a device reset is required.

For a list of supported DSP templates, see SBC and DSP
Channel Capacity on page 1061.
Table 58-39: DTMF Parameters
Determines the DTMF transport type.

[0] Mute DTMF = DTMF digits are removed from the voice
stream and are not relayed to remote side.

[2] Transparent DTMF = DTMF digits remain in the voice
stream.

[3] RFC 2833 Relay DTMF = (Default) DTMF digits are removed
from the voice stream and are relayed to remote side according
to RFC 2833.

[7] RFC 2833 Relay Decoder Mute = DTMF digits are sent
according to RFC 2833 and muted when received.
Note: The parameter is automatically updated if the parameters
FirstTxDTMFOption or RxDTMFOption are configured.
Defines the DTMF gain control value (in decibels) to the Tel side.
The valid range is -31 to 0 dB. The default is -11 dB.
Note: The parameter can also be configured in a Tel Profile.
Defines the range (in decibels) between the high and low frequency
components in the DTMF signal. Positive decibel values cause the
higher frequency component to be stronger than the lower one.
Negative values cause the opposite effect. For any parameter
value, both components change so that their average is constant.
The valid range is -10 to 10 dB. The default is 0 dB.
Note: For the parameter to take effect, a device reset is required.
Defines the time (in msec) between generated DTMF digits to the
Tel side (if FirstTxDTMFOption = 1, 2 or 3).
