RTP, RTCP and T.38 Parameters

The RTP, RTCP and T.38 parameters are described in the table below.
'Dynamic Jitter Buffer Minimum
Delay'
configure voip > media
rtp-rtcp > jitter-buffer-
minimum-delay
[DJBufMinDelay]
'Dynamic Jitter Buffer Optimization
Factor'
configure voip > media
rtp-rtcp > jitter-buffer-
optimization-factor
[DJBufOptFactor]
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.
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.
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.
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).

Parameter
Description
Description
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
Note: If the feature is configured for a specific profile,
the settings of the global parameter is ignored for calls
associated with the profile.
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
Note: If the feature is configured for a specific profile,
the settings of the global parameter is ignored for calls
associated with the profile.
