Profiles (TelProfile_DtmfVolume). For a detailed description of the
parameter and for configuring the functionality in the Tel Profiles
table, see Configuring Tel Profiles on page 439.
Note: If the functionality is configured for a specific Tel Profile, the
settings of the global parameter is ignored for calls associated with
the Tel Profile.
Defines the range (in decibels) between the high and low frequency
components in the DTMF signal. Positive decibel values cause the
higher frequency component to be stronger than the lower one.
Negative values cause the opposite effect. For any parameter
value, both components change so that their average is constant.
The valid range is -10 to 10 dB. The default is 0 dB.
Note:

For the parameter to take effect, a device reset is required.
Defines the time (in msec) between generated DTMF digits to the
Tel side (if FirstTxDTMFOption = 1, 2 or 3).
The valid range is 0 to 32767. The default is 100.
Defines the time (in msec) for generating DTMF tones to the Tel
side (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 to the Tel side that arrive as Relay from the IP side.
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 at the Tel 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.
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 other (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).
Table 67-39: RTP/RTCP and T.38 Parameters
Global parameter defining the minimum delay (in msec) of the
device's dynamic Jitter Buffer.
You can also configure the functionality per specific calls,
using IP Profiles (IpProfile_JitterBufMinDelay) or Tel Profiles
(TelProfile_JitterBufMinDelay). For a detailed description of
