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 or analog
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.
EMS: DTMF Inter Interval
(msec)
[DTMFInterDigitInterval]
Defines the time (in msec) between generated DTMF digits to
PSTN side (if TxDTMFOption = 1, 2 or 3).
The default is 100 msec. The valid range is 0 to 32767.
EMS: DTMF Length (msec)
[DTMFDigitLength]
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 is 100.
EMS: Rx DTMF Relay Hang
Over Time (msec)
[RxDTMFHangOverTime]
Defines the Voice Silence time (in msec) after playing DTMF or MF
digits to the Tel/PSTN side that arrive as Relay from the IP side.
Valid range is 0 to 2,000 msec. The default is 1,000 msec.
EMS: Tx DTMF Relay Hang
Over Time (msec)
[TxDTMFHangOverTime]
Defines the Voice Silence time (in msec) after detecting the end of
DTMF or MF digits at the Tel/PSTN side when the DTMF Transport
Type is either Relay or Mute.
Valid range is 0 to 2,000 msec. The default is 1,000 msec.
Web/EMS: NTE Max Duration
[NTEMaxDuration]
Defines the maximum time for sending Named Telephony Events /
NTEs (RFC 4733/2833 DTMF relay) to the IP side, regardless of
the DTMF signal duration on the TDM side.
The range is -1 to 200,000,000 msec. The default is -1 (i.e., NTE
stops only upon detection of an End event).
