works fine for me :)
*DialPlan*
<condition field="destination_number" expression="^1234$">
<action application="answer" />
<action application="javascript" data="test.js" />
</condition>
*test.js*
result = apiExecute("sched_api","+5 "+session.uuid+" jsrun /scripts/inc.js
"+session.uuid);
console_log("notice", "entering loop\n");
while (session.ready())
{
//sit here whilst the call is still connected
}
console_log("notice", "call ended\n");
*inc.js*
include("includes/General.js"); //this includes a function "Output" to log
to screen
var session = new Session(argv[0]);
if (session.ready()) {
Output("TIMEOUT");
session.execute("playback", "/sounds/en/us/callie/test.wav");
session.execute("sleep","500");
session.hangup();
}
exit("TIMEOUT");
Thanks
Matt
