[arm-allstar] Audio Files - Play only when there has not been any traffic

[Patrick Perdue]

This is pretty open-ended, really.

Without actually writing anything (don't have time right now), I can 
think of a few ways to do it.

One way would be to attach a script or command to an event as defined in 
the events stanza of your node, something like:

[events<yournodenumber>

touch /tmp/tx = s|t|RPT_ETXKEYED
rm /tmp/tx = s|f|RPT_ETXKEYED

In this example, a file is created in /tmp when someone is transmitting 
toward the node, and removed when the transmission stops.

Now, you could write a simple script that plays a file only if /tmp/tx 
doesn't exist, then call it with cron, drive it manually or whatever.

/etc/asterisk/local/notx-announcement.sh

#!/bin/bash
if [ -e /tmp/tx ]
then
echo "nothing to do. Exiting."
exit
else
asterisk -rx "rpt playback <yournode> /etc/asterisk/local/some_file
fi


NOTE! THIS IS UNTESTED!


You could do more sophisticated things, like using timers (sleep) such 
that a file is automatically played after <x> seconds of inactivity 
instead of using the temp file method.

Come to think of it, you could probably also do something with 
lnkacttime, lnkactmacro, and remote_inact_timeout, though I've never 
tried using it that way, either.
