Table 5-30: Media Settings, Hook-Flash Settings Parameters
Parameter Description
Min. Flash-Hook Detection Period
[msec]
[MinFlashHookTime]
Sets the minimal time (in msec) for detection of a flash-hook event (for
FXS only).
The valid range is 25 to 300. The default value is 300 msec.
Detection is guaranteed for flash hook periods of at least 60 msec (when
setting the minimal time to 25). Flash-hook signals that last a shorter
period of time are ignored.
Note: It's recommended to reduce the detection time by 50 msec from
the desired value (e.g. if you set the value to 200 msec, then enter 150
msec (i.e. 200 minus 50).
Max. Flash-Hook Detection Period
[msec]
[FlashHookPeriod]
Defines the flash-hook period (in msec) for both analog and IP sides.
For the analog side it defines:
- The maximal hook-flash detection period (for FXS gateways). A longer
signal is considered offhook / onhook event.
- The hook-flash generation period (for FXO gateways).
For the IP side it defines the flash-hook period that is reported to IP.
The valid range is 25 to 1500. The default value is 700 msec.
Note: For FXO gateways, a constant of 90 msec must be added to the
required hook-flash period. For example, to generate a 450 msec hook-
flash, set ‘FlashHookPeriod’ to 540.
