Parameter Description
EMS: UDT Detector Frequency
Deviation
Defines the deviation (in Hz) allowed for the detection of each
signal frequency.
The valid range is 1 to 50. The default value is 50.
[UDTDetectorFrequencyDeviation]
Note:
EMS: CPT Detector Frequency
Deviation
For this parameter to take effect, a device reset is
required.
Defines the deviation (in Hz) allowed for the detection of each
CPT signal frequency.
The valid range is 1 to 30. The default value is 10.
[CPTDetectorFrequencyDeviation]
Note:
For this parameter to take effect, a device reset is
required.
Defines when the detection of DTMF events is notified.
[MGCPDTMFDetectionPoint]
 [0]

= DTMF event is reported at the end of a detected
DTMF digit.
[1]
= DTMF event is reported at the start of a detected
DTMF digit (default).
Web/EMS: Hook-Flash Option
[HookFlashOption]

Determines the hook-flash transport type (i.e., method by
which hook-flash is sent and received).

[0] Not Supported = Hook-Flash indication isn't sent
(default).

[1] INFO = Send proprietary INFO message with Hook-
Flash indication.

[4] RFC 2833

[5] INFO (Lucent) = Send proprietary SIP INFO message
with Hook-Flash indication.
[6] INFO (NetCentrex) = Send proprietary SIP INFO
message with Hook-Flash indication. The SIP INFO
message is sent by the device as follows:
Content-Type: application/dtmf-relay
Signal=16
Where 16 is the DTMF code for hook flash

Notes:

The FXO interfaces support the receipt of RFC 2833 Hook-
Flash signals and INFO [1] type only.
The FXS interfaces send Hook-Flash signals only if the
parameter EnableHold is set to 0.
Min. Flash-Hook Detection Period
[msec]
[MinFlashHookTime]
Defines the minimum time (in msec) for detection of a hook-
flash event. Detection is guaranteed for hook-flash periods of
at least 60 msec (when setting the minimum time to 25).
Hook-flash signals that last a shorter period of time are
ignored.
The valid range is 25 to 300. The default value is 300.

Notes:

This parameter is applicable only to FXS interfaces.

It's recommended to reduce the detection time by 50 msec
from the desired value (e.g., if you want to set the value to
200 msec, then enter 150 msec (i.e., 200 minus 50).
For this parameter to take effect, a device reset is
required.
