Parameter
Table 60-33:DTMF Parameters
Defines the DTMF transport type.
■ [0] Mute DTMF = DTMF digits are removed from the voice
stream and are not relayed to remote side.
■ [2] Transparent DTMF = DTMF digits remain in the voice
stream.
■ [3] RFC 2833 Relay DTMF = (Default) DTMF digits are
removed from the voice stream and are relayed to the remote
side according to RFC 2833.
■ [7] RFC 2833 Relay Decoder Mute = DTMF digits are sent
according to RFC 2833 and muted when received.
Note: The parameter is automatically updated if the parameters
[FirstTxDTMFOption] or [RxDTMFOption] are configured.
Global parameter defining the DTMF gain control value (in
decibels).
Note: If the feature 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 if
FirstTxDTMFOption = 1, 2 or 3.
The valid range is 0 to 32767. The default is 100.
Description
Defines the number (20 msec) of coder payloads used to
generate a fax/modem bypass packet.
The valid range is 1, 2, or 3 coder payloads. The default is
1 coder payload.
