Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
■ [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.
'DTMF Volume' (-31 to 0
dB)
configure voip >
media voice > DTMF-
volume
[DTMFVolume]
Global parameter defining the DTMF gain control value (in
decibels). For analog interfaces, this is the gain control to the Tel
side.
You can also configure the feature per specific calls, using Tel
Profiles (TelProfile_DtmfVolume). For a detailed description of
the parameter and for configuring the feature in the Tel Profiles
table, see Configuring Tel Profiles.
Note: If the feature is configured for a specific Tel Profile, the
settings of the global parameter is ignored for calls associated
with the Tel Profile.
DTMF Generation Twist
configure voip >
media voice > DTMF-
generation-twist
[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 the parameter to take effect, a device reset is
required.
inter-digit-
interval
[DTMFInterDigitInterval]
Defines the time (in msec) between generated DTMF digits (to
the Tel side for the Gateway application) if FirstTxDTMFOption
= 1, 2 or 3.
The valid range is 0 to 32767. The default is 100.
[DTMFDigitLength] Defines the time (in msec) for generating DTMF tones (to the Tel
side for the Gateway application) if FirstTxDTMFOption = 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 is 100.
configure voip >
media voice >
digit-hangover-
time-rx
[RxDTMFHangOverTime]
Defines the Voice Silence time (in msec) after playing DTMF or
MF digits (to the Tel side for the Gateway application) that arrive
as Relay (from the IP side for the Gateway application).
Valid range is 0 to 2,000 msec. The default is 1,000 msec.
configure voip >
media voice >
digit-hangover-
time-tx
[TxDTMFHangOverTime]
Defines the Voice Silence time (in msec) after detecting the end
of DTMF or MF digits (on the Tel side for the Gateway
application) when the DTMF Transport Type is either Relay or
Mute.
Valid range is 0 to 2,000 msec. The default is 1,000 msec.
