User's Manual 856 Document #: LTRT-12809
Mediant 800 MSBR
Parameter Description

[5] INFO (Lucent) = Sends proprietary SIP INFO message with
Hook-Flash indication. The device sends the INFO message as
follows:
Content-Type: application/hook-flash
Content-Length: 11
signal=hf
 [6] INFO (NetCentrex) = Sends proprietary SIP INFO message
with Hook-Flash indication. The device sends the INFO message
as follows:
Content-Type: application/dtmf-relay
Signal=16
Where 16 is the DTMF code for hook flash.
 [7] INFO (HUAWAEI) = Sends a SIP INFO message with Hook-
Flash indication. The device sends the INFO message as follows:
Content-Length: 17
Content-Type: application/sscc
event=flashhook
Notes:
 The device can interwork DTMF HookFlashCode to SIP INFO
messages with Hook Flash indication (for digital interfaces).
 FXO interfaces support only the receipt of RFC 2833 Hook-Flash
signals and INFO [1] type.
 FXS interfaces send Hook-Flash signals only if the EnableHold
parameter is set to 0.
Web: Min. Flash-Hook
Detection Period [msec]
EMS: Min Flash Hook
Time
CLI: min-flash-hook-time
[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 is 300.
Notes:
 For this parameter to take effect, a device reset is required.
 This parameter is applicable only to FXS interfaces.
 It's recommended to reduce the detection time by 50 msec from
the desired value. For example, if you want to set the value to 200
msec, then enter 150 msec (i.e., 200 minus 50).
Web: Max. Flash-Hook
Detection Period [msec]
EMS: Flash Hook Period
CLI: flash-hook-period
[FlashHookPeriod]
Defines the hook-flash period (in msec) for both Tel and IP sides (per
device). For the IP side, it defines the hook-flash period that is
reported to the IP.
For the analog side, it defines the following:
 FXS interfaces:

Maximum hook-flash detection period. A longer signal is
considered an off-hook or on-hook event.

Hook-flash generation period upon detection of a SIP INFO
message containing a hook-flash signal.
 FXO interfaces: Hook-flash generation period.
The valid range is 25 to 3,000. The default is 700.
Notes:
 For this parameter to take effect, you need to reset the device.
 For FXO interfaces, a constant of 100 msec must be added to the
required hook-flash period. For example, to generate a 450 msec
