[Freeswitch-users] exit lua script in hangup hook

25 Jan 2012

      Hello,

i'm trying to exit my lua script (called from dialplan) to exit in the the hanguphook:

function on_hangup(s,status)
        freeswitch.consoleLog("NOTICE","---- on_hangup: "..status.."\n");
        error();
end

freeswitch.consoleLog("NOTICE","---- ANSWER:\n");
session:answer();
freeswitch.consoleLog("NOTICE","---- SETHOOK: \n");
session:setHangupHook("on_hangup");

while (session:ready() == true) do
        freeswitch.consoleLog("NOTICE","---- START OF LOOP \n");
        freeswitch.consoleLog("NOTICE","---- STREAMFILE \n");
        session:streamFile("/usr/local/freeswitch/sounds/en/us/callie/ivr/8000/ivr-on_hold_indefinitely.wav");
        freeswitch.consoleLog("NOTICE","---- END OF SCRIPT 1 -> HANGUP\n");
end

freeswitch.consoleLog("NOTICE","---- END OF SCRIPT 2 -> HANGUP\n");
session:hangup()

When I hangup during the  streamFile Call, I geht the following output:

Why does the hangup handler return and the rest of the script is executed ?
I event tried "do return end;" , "exit;" ," exit();" instead of "error(); - none of them works.

If i put the same logic into javascript, the hook works and the script is terminated:

function on_hangup(s,status)
{
        console_log("NOTICE","---- hangup "+status+"\n");
        return "exit";
}

console_log("NOTICE","---- ANSWER\n");
session.answer();
console_log("NOTICE","---- ANSWER\n");
session.setHangupHook(on_hangup);

while(session.ready())
{
        console_log("NOTICE","---- START OF LOOP\n");
        session.streamFile("/usr/local/freeswitch/sounds/en/us/callie/ivr/8000/ivr-on_hold_indefinitely.wav");
        console_log("NOTICE","---- END OF LOOP\n");
}
console_log("NOTICE","---- END OF SCRIPT\n");
session.hangup();

Any suggestions ? Or do i miss something here ?

The dialplan part:

    <extension name="hanguptest">
     <condition field="destination_number" expression="^(3001)$">
        <action application="set" data="session_in_hangup_hook=true"/>
       <action application="lua" data="hangup.lua"/>
     </condition>
    </extension>

(replace hangup.lua with hangup.js for the javascript version)
