Version 6.8 611 Mediant 2600 E-SBC
User's Manual 43. Configuration Parameters Reference
Parameter Description
CLI: inter-digit-interval
[DTMFInterDigitInterval]
PSTN side (if TxDTMFOption = 1, 2 or 3).
The valid range is 0 to 32767. The default is 100.
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)
CLI: default-dtmf-signal-
duration
[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)
CLI: digit-hangover-time-tx
[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
CLI: telephony-events-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).
43.9.4 RTP, RTCP and T.38 Parameters
The RTP, RTCP and T.38 parameters are described in the table below.
Table 43-36: RTP/RTCP and T.38 Parameters
Parameter Description
Web: Dynamic Jitter Buffer Minimum
Delay
EMS: Minimal Delay (dB)
CLI: jitter-buffer-minimum-delay
[DJBufMinDelay]
Global parameter that defines the minimum delay (in msec) of
the device's dynamic Jitter Buffer. You can also configure this
functionality per specific calls, using IP Profiles
(IpProfile_JitterBufMinDelay). For a detailed description of this
parameter and for configuring this functionality in the IP Profile
table, see Configuring IP Profiles on page 297.
Note: If this functionality is configured for a specific profile, the
settings of this global parameter is ignored for calls associated
with the profile.
Web: Dynamic Jitter Buffer
Optimization Factor
EMS: Opt Factor
CLI: jitter-buffer-optimization-factor
[DJBufOptFactor]
Global parameter that defines the Dynamic Jitter Buffer frame
error/delay optimization factor. You can also configure this
functionality per specific calls, using IP Profiles. For a detailed
description of this parameter and for configuring this
functionality in the IP Profile table, see Configuring IP Profiles
on page 297.
Note: If this functionality is configured for a specific profile, the
settings of this global parameter is ignored for calls associated
with the profile.
