CHAPTER 60 Configuration Parameters Reference
Mediant 4000 SBC | User's Manual
Parameter Description
[DTMFDigitLength] Defines the time (in msec) for generating DTMF tones 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 that arrive as Relay .
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 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 -- , regardless of
the DTMF signal duration on the other 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).
RTP, RTCP and T.38 Parameters
The RTP, RTCP and T.38 parameters are described in the table below.
Table 60-34: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). For a
detailed description of the parameter and for
configuring the feature, see
Configuring IP 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.
You can also configure the feature per specific calls,
using IP Profiles (IpProfile_JitterBufOptFactor) . For a
detailed description of the parameter and for
configuring the feature, see
Configuring IP 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.
