Web: DSP Version Template
Number
EMS: Version Template
Number
[DSPVersionTemplateNumbe
r]
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.

53.10.3 DTMF Parameters
The dual-tone multi-frequency (DTMF) parameters are described in the table below.
DTMF Parameters
Parameter Description
Web/EMS: DTMF Transport
Type
[DTMFTransportType]
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: This parameter is automatically updated if the parameters
TxDTMFOption or RxDTMFOption are configured.
Web: DTMF Volume (-31 to 0
dB)
EMS: DTMF Volume (dBm)
[DTMFVolume]
Defines the DTMF gain control value (in decibels) to the PSTN
side.
The valid range is -31 to 0 dB. The default is -11 dB.
Note: This parameter can also be configured in a Tel Profile.
Web: DTMF Generation Twist
EMS: DTMF Twist Control
[DTMFGenerationTwist]
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 this parameter to take effect, a device reset is required.
