Thanks.  Yes, of course I meant zapata.conf, sorry.  

I've tried changing each of these settings:
; prewink:     Pre-wink time (default 50ms)
; preflash:    Pre-flash time (default 50ms)
; wink:        Wink time (default 150ms)
; flash:       Flash time (default 750ms)
; start:       Start time (default 1500ms)
; rxwink:      Receiver wink time (default 300ms)
; rxflash:     Receiver flashtime (default 1250ms)
; debounce:    Debounce timing (default 600ms)

Even when I set rxflash=1 and restart Asterisk, the flash-hold is
still enabled... it might shorten the amount of time before hangup,
but what I really need is to completely disable the flash-hold and
hangup as soon as the flash is received.  Perhaps this has something
to do with another parameter such as debounce?  Is there any
documentation that describes in depth what those parameters actually
do?
