AudioCodes Mediant 2600 - DTMF Parameters

User's Manual 610 Document #: LTRT-42060
Mediant 2600 E-SBC
Parameter Description
EMS: VBR Coder Hangover
CLI: VBR-coder-hangover
[VBRCoderHangover]
Defines the required number of silence frames at the beginning of
each silence period when using the VBR coder silence
suppression.
The range is 0 to 255. The default is 1.
Web: AMR Payload Format
[AmrOctetAlignedEnable]
Defines the AMR payload format type.
 [0] Bandwidth Efficient
 [1] Octet Aligned (default)
EMS: AMR Coder Header
Format
[AMRCoderHeaderFormat]
Determines the payload format of the AMR header.
 [0] = Non-standard multiple frames packing in a single RTP
frame. Each frame has a CMR and TOC header.
 [1] = AMR frame according to RFC 3267 bundling.
 [2] = AMR frame according to RFC 3267 interleaving.
 [3] = AMR is passed using the AMR IF2 format.
Note: Bandwidth Efficient mode is not supported; the mode is
always Octet-aligned.
43.9.3 DTMF Parameters
The dual-tone multi-frequency (DTMF) parameters are described in the table below.
Table 43-35: DTMF Parameters
Parameter Description
Web/EMS: DTMF Transport
Type
CLI: 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)
CLI: DTMF-volume
[DTMFVolume]
Defines the DTMF gain control value (in decibels) to the side.
The valid range is -31 to 0 dB. The default is -11 dB.
Web: DTMF Generation Twist
EMS: DTMF Twist Control
CLI: 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 this parameter to take effect, a device reset is required.
EMS: DTMF Inter Interval
(msec)
Defines the time (in msec) between generated DTMF digits to
