Parameter Description
Content-Length: 17
event flashhook
 [4] RFC 2833 = This option is currently not supported.
 [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 (HUAWEI) = 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
Note:
 Digital interfaces: The device can interwork DTMF
HookFlashCode to SIP INFO messages with Hook Flash
indication.
 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.

flash-from-media-ip
[HookFlashFromMediaIP]
Defines the device’s handling of hook-
flash telephony events
that are received in the media (RTP) from the IP side
(typically, RFC 2833) and then sent to the PSTN CAS side.
 [0] = (Default) The device ignores incoming hook-flash
events from the media IP.
 [1] = The device generates a wink to the CAS side when
it receives a hook-flash event from the media IP.
Note: The parameter is applicable only to E1/T1 CAS
interfaces.
Min. Flash-Hook Detection Period
configure voip > interface fxs-fxo >
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.
Note:
 The 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
