AudioCodes Mediant 1000B - DTMF Parameters

Version 7.2 1101 Mediant 1000B Gateway & E-SBC
User's Manual 65. Configuration Parameters Reference
Parameter Description
DSP Version Template Number
configure voip > media settings
> DSP-version-template-
number
[DSPVersionTemplateNumber]
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 temp
lates to analog and digital modules
using the syntax DSPVersionTemplateNumber=xy
where:
 x = 0 or 1 for DSP templates of analog modules
 y = 0 to 5 for DSP templates of digital and MPM modules
Note:
 For the parameter to take effect, a device reset is required.
 For a list of supported DSP templates, see Channel Capacity on
page 1273.
65.9.3 DTMF Parameters
The dual-tone multi-frequency (DTMF) parameters are described in the table below.
Table 65-36: DTMF Parameters
Parameter Description
DTMF Transport Type
configure voip > media voice >
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: 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)
to the Tel side.
You can also configure the functionality per specific calls, using Tel
Profiles (TelProfile_DtmfVolume). For a detailed description of the
parameter and for configuring the functionality in the Tel Profiles
table, see Configuring Tel Profiles on page 459.
Note: If the functionality 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.
