CHAPTER68 Configuration Parameters Reference
Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
[DTMFDigitLength] Defines the time (in msec) for generating DTMF tones (to the Tel
side for the Gateway application) if FirstTxDTMFOption = 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.
configure voip >
media voice >
digit-hangover-
time-rx
[RxDTMFHangOverTime]
Defines the Voice Silence time (in msec) after playing DTMF or
MF digits (to the Tel side for the Gateway application) that arrive
as Relay (from the IP side for the Gateway application).
Valid range is 0 to 2,000 msec. The default is 1,000 msec.
configure voip >
media voice >
digit-hangover-
time-tx
[TxDTMFHangOverTime]
Defines the Voice Silence time (in msec) after detecting the end
of DTMF or MF digits (on the Tel side for the Gateway
application) when the DTMF Transport Type is either Relay or
Mute.
Valid range is 0 to 2,000 msec. The default is 1,000 msec.
'NTE Max Duration'
configure voip >
media voice >
telephony-events-
max-duration
[NTEMaxDuration]
Defines the maximum time for sending Named Telephony
Events / NTEs -- RFC 4733/2833 DTMF relay -- (to the IP side
for the Gateway application), regardless of the DTMF signal
duration on the other side (TDM for the Gateway application).
The range is -1 to 200,000,000 msec. The default is -1 (i.e., NTE
stops only upon detection of an End event).
RTP, RTCP and T.38 Parameters
The RTP, RTCP and T.38 parameters are described in the table below.
Table 68-34:RTP/RTCP and T.38 Parameters
Parameter Description
'Dynamic Jitter Buffer Minimum
Delay'
configure voip > media rtp-
rtcp > jitter-buffer-
minimum-delay
[DJBufMinDelay]
Global parameter defining the minimum delay (in
msec) of the device's dynamic Jitter Buffer.
You can also configure the feature per specific calls,
using IP Profiles (IpProfile_JitterBufMinDelay) or Tel
Profiles (TelProfile_JitterBufMinDelay). For a detailed
description of the parameter and for configuring the
feature, see Configuring IP Profiles or Configuring Tel
Profiles.
Note: If the feature is configured for a specific profile,
the settings of the global parameter is ignored for calls
associated with the profile.
'Dynamic Jitter Buffer Optimization
Factor'
configure voip > media rtp-
rtcp > jitter-buffer-
optimization-factor
[DJBufOptFactor]
Global parameter defining the Dynamic Jitter Buffer
frame error/delay optimization factor.
