Sometimes I have the IMMESURABLE pleasure of posting and sharing the solution of a problem I had…

The problem:

I wanted to be able to :

• Broadcast a soundfile saying “30 seconds left” … to both parties
• Terminating a call

After having calculated the max time allowed for a call

In both cases of:

• Digital lines (that have the “on answer” event)
• Analogue lines (that DON’T; therefore I use a “grace” period from when dialing ends…

All this in javascript..

So I did:

                var endSecs = secsMax + secsGrace;

                var warnSecs = secsMax +secsGrace - 30;            

where secsGrace is ZERO for digital lines …

then, for digital I use after the session out ready, so :

if (sessOut.ready())         {

                                               sessOut.execute("set", "execute_on_answer_1=sched_broadcast +" + warnSecs + " playback::" + soundDir + "time_off.wav both");

                                               sessOut.execute("set", "execute_on_answer_2=sched_hangup +" + endSecs);

}

And for analogue, BEFORE thesessout ready

                               sessOut.execute("sched_hangup",  "+" + endSecs + " alloted_timeout");

                               sessOut.execute("sched_broadcast", "+" + warnSecs + " " + soundDir + "time_off.wav both");

Tried and tested..

I HOPE it helps someone

Subject: [Freeswitch-users] warn and hangup after xx seconds

I am scripting in js

I have both analogue and digital trunks out (analogue trunks out don’t give me the “answer” event)

Lets say we have a “totTime” variable for max length of call

I need to play a warning at totTime – 30

And hangup at totTime..

I have tried using:

sessOut.execute("set", "execute_on_answer_1=sched_hangup +” + totTime + “ alloted_timeout");

sessOut.execute("set", "execute_on_answer_2=sched_broadcast +” + (totTime – 30) + “layback::" + soundDir + "time_off.wav both");

But I can only get one or the other to work.. never both!

Also, how would I schedule there two events for analogue lines (where I don’t have “on_answer”)

Thanks all
