Minimum Duration
at OFF
Set the minimum duration at OFF for the DTMF signal. Range of value: 10
～
2000,
calculated by ms. The default value is 36.
Ratio of DT Energy
Set the percentage of energy in the DTMF signal. The value range is 1-100 and the
default value is 83.8.
Lowest Energy
Threshold
Set the minimum energy threshold of the DTMF signal. Range of value: -40~9. The
default value is -21.

Once this feature is enabled, the gateway can detect the DTMF digits A, B, C and D
(Case-insensitive). The default value is disabled.
DTMF Energy
Advance Set
When this function is enabled, different high frequency energy and low frequency
energy can be configured for different DTMFs. By default the feature is disabled.
DTMF Energy

calculated by ms, with the default value of 100.
Duration at OFF
Set the duration of the DTMF signal at OFF state. Range of value: 0~16383,

3.5.6 Ringing Scheme
On the Ringing Scheme Configuration interface, the gateway can execute different ringing
schemes according to the CallerID or Alert-Info..
The table below explains the items shown on the interface.
Item
Description
CallerID
The gateway will match the CallerID set in this item to that of the incoming call. If
they are matched, the current ringing scheme will be executed; otherwise, the
default ringing scheme (1 sec on and 4 sec off) will work.
The rule to fill in the CallerID is the same as that of
. Multiple CallerIDs
are supported; they should be separated by “,”
Alert-Info Value
The gateway will match the alert-info value set in this item to that of the incoming
call. If they are matched, the current ringing scheme will be executed; otherwise,
the default ringing scheme (1 sec on and 4 sec off) will work..
Ringing Scheme
The ringing scheme can be “1,X,Y” or “2,X,Y,M,N”, in which, the number 1 or 2
denotes one group or two groups; X, M denote the duration at on state while Y, N
denote the duration at off state.
Note: The duration at ON or OFF cannot be greater than 12000ms, the total
duration at ON and OFF cannot be greater than 16000ms, and N - the last duration
at OFF cannot be less than 1800ms if the item “Occasion to Send FSK CallerID” is
set to After the first ring.
