Mediant 3000
Parameter Description
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).

[DJBufOptFactor]
Defines the Dynamic Jitter Buffer frame error/delay optimization
factor.
The valid range is 0 to 12. The default factor is 10.
Notes:

For data (fax and modem) calls, set this parameter to 12.

This parameter can also be configured in an IP Profile and/or a
Tel Profile.
