Parameter Description
Min. Flash-Hook Detection Period
[msec]
[MinFlashHookTime]
Minimum threshold in msec + 50 msec for detection of hook-flash.
Relevant only for MediaPack/FXS gateways.
25 to 300, (default = 300).
Max. Flash-Hook Detection Period
[msec]
[FlashHookPeriod]
300 to 1500 (default 400) hook-flash time in msec. The parameter is used for
