Version 6.4
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 this parameter to take effect, a device reset is required.

For a list of supported DSP templates, see DSP Templates on
page 655.
Table A-34: DTMF Parameters
Determines the DTMF transport type.

[0] DTMF Mute = Erases digits from voice stream and doesn't
relay to remote.

[2] Transparent DTMF = Digits remain in voice stream.

[3] RFC 2833 Relay DTMF = Erases digits from voice stream
and relays to remote according to RFC 2833 (default).

[7] RFC 2833 Relay Rcv Mute = DTMFs are sent according to
RFC 2833 and muted when received.
Note: This parameter is automatically updated if the parameters
TxDTMFOption or RxDTMFOption are configured.
Defines the DTMF gain control value (in decibels) to the PSTN side.
The valid range is -31 to 0 dB. The default value is -11 dB.
Note: This parameter can also be configured per Tel Profile, using
the TelProfile parameter.
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 value is 0 dB.
Note: For this parameter to take effect, a device reset is required.
Defines the time (in msec) between generated DTMF digits to
PSTN side (if TxDTMFOption = 1, 2 or 3).
The default value is 100 msec. The valid range is 0 to 32767.
Defines the time (in msec) for generating DTMF tones to the PSTN
side (if TxDTMFOption = 1, 2 or 3). It also configures the duration
that is sent in INFO (Cisco) messages.
The valid range is 0 to 32767. The default value is 100.
