Telephone system:Closing announcement

While this script is not in use anymore, since we're a 24/7 space now, it still is fun to trigger announcements using cron jobs

it used to trigger on 9:30PM on weekdays, and 4:30PM on saturday. At first I tried to retrigger the events in the dialplan for the next occurrence, but cron jobs are way more reliable (and easier)

crontab for freeswitch user

30  21  *   *   1-5 /usr/local/freeswitch/bin/fs_cli -x "originate loopback/1399 closure"
30  16  *   *   6   /usr/local/freeswitch/bin/fs_cli -x "originate loopback/1399 closure"

paging.js

This script takes the dialstring of all members withing call group 'intercom' and puts them as conference-auto-out-call separately. After that, the conference is started with the sound extension, and all parsed extensions will be called automatically (assuming that extension has auto-answer for that line) When the sound extension is done and hangs up, everyone is kicked out of the conference.

if (session.ready())
{
    session.answer();

    console_log(4, "building-wide paging\n");

    session.execute("set","pageGroup=${group_call(intercom@${domain_name}+E)}\n");
    var pageGroup = session.getVariable("pageGroup");
    var arrPageGroup = pageGroup.split( ":_:" );
    for ( var idx = 0; idx < arrPageGroup.length; idx++ )
    {
        var user = arrPageGroup[ idx ];
        user = user.replace( /\n/g, "" );
        user = user.replace( /\[[^\]]*\](.*)/g, "$1" );
        session.execute("conference_set_auto_outcall", user);
    }
}

dialplan

The announcement consists of two parts: triggering a group-intercom and executing a 'closure' extension which played the appropriate sounds
