hi,
in "nibblebill" module of freeswitch, billing will only occur at the every 60 second by set like:( <action application="nibblebill" data="heartbeat 60"/>)
but while making call and call is answered  the minimmun amount of cash is reduced and also  billing is done every 60 seconds,
(in addition of billing every 60 seconds the minimmum amount of cash also reduced at the first time the call is answered)
is it possible to set somethings so that don't reduce (billing)  the minimum amount of cash at the same time call is answered and only billing every 60 second?
  
thanks so much
