If Receive Activity Mode is set to "VAD", the Hang Time determines
how long the voice transmission will continue to be received after the
voice is no longer present. Acceptable value range is 0 to 5000
msec. (Default setting is 500 msec).
If Receive Activity Mode is set to "GPIO", set the GPIO Active Level
to either High or Low (Default setting is Low).
For DTMF mode, controls the sensitivity of tone detection on
incoming DTMF. Acceptable values -35 to 0 dBFS. (Default setting is
-20 dBFS)
For VAD mode, controls the sensitivity of voice detection on
incoming audio. Acceptable values -40 to 20 dBFS. (Default setting is
-35 dBFS)
Sets the gain (in dB) applied to the hardware in the radio to receive
audio. Acceptable values -20 to 20 dB. (Default setting is 0 dB).
Sets the gain (in dB) applied to the software in the radio to receive
audio. Acceptable values -40 to 20 dB. (Default setting is -20 dB).
Phrase of DTMF digits which, when received from the radio, will
cause the RGW to enter dialing mode. Subsequent digits will be
accumulated into a phone number buffer, and a call will be placed to
that number once the user stops dialing. Acceptable values are any
string of valid DTMF digits (0-9, *, #) (Default setting is "**")
Phrase of DTMF digits which, when received from the radio, will
cause any ongoing call or operation to terminate. Acceptable values
are any string of valid DTMF digits (0-9, *, #) (Default setting is
"##")
When the radio user is entering a number in dialing mode, how long to
wait, in seconds, after receiving a DTMF digit before concluding that
the user is done entering the target number. After this timeout elapses,
a call is attempted to the target number. Acceptable values > 0 sec.
(Default setting is 3 sec)
The maximum length of a phone number that may be entered by a
radio user in dialing mode, including any prefixes such as country
code and external calling access digit. The phrase used to initiate
dialing (e.g., "**") does not count towards the maximum number of
digits. Acceptable values > 0. (Default setting is 20)
When a radio-initiated outbound call is being placed, a burst of ring
back tone is transmitted to the radio user for this amount of time as
confirmation. Acceptable values > 0 msec. (Default value is 1000
msec).
When an active call is hung up, a burst of busy tone is transmitted to
the radio user for this amount of time. Acceptable values ≥ 0 msec.
(Default value is 2000 msec)
