User's Manual
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 (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 (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).
Table 60-37: RTP/RTCP and T.38 Parameters
Global parameter that defines the device's handling of calls if
RTP packets are not received within a user-defined timeout
(configured by the BrokenConnectionEventTimeout parameter).
You can also configure this functionality per specific calls, using
IP Profiles (IpProfile_DisconnectOnBrokenConnection). For a
detailed description of the parameter and for configuring this
functionality in the IP Profiles table, see 'Configuring IP Profiles'
on page 418.
Note: If this functionality is configured for a specific IP Profile,
the settings of this global parameter is ignored for calls
associated with the IP Profile.
Defines the timeout interval (in 100-msec units) after which a
call is disconnected if an RTP packet is not received during an
884
