# timer_rebeep.agi
#
# This script is designed to be launched from the in-group/campaign timer
# setting to set another trigger event for the next X seconds. Often used for
# calls that need to have a periodic beep signifying that the call is being
# recorded
#
# Just add the following to the System Settings Custom Dialplan Entry
# and set rebuild conf=Y
# exten => 8399,1,Answer
# exten => 8399,n,Wait(1)
# exten => 8399,n,Playback(beep)
# exten => 8399,n,AGI(timer_rebeep.agi,20---D1_DIAL_QUIET)
# exten => 8399,n,Hangup
#
# ; Below are the parameters needed for the script to be run properly
# ; 1. seconds delay before next trigger goes
# ; 2. timer action to launch
#
# Then set the in-groups/campaigns that you want to have this enabled
#   "Timer Action" = D1_DIAL_QUIET
#   "Timer Action Seconds" = 20
#   "Transfer Conf Number 1" = 8399
