[Freeswitch-users] Lua session originate - freeswitch crash

[Eric Beard]

Ok, so I got a little further by trial and error, and realized the 4th arg is due to lua function calling syntax.  If you use the dot notation on a function declared with a colon, it expects "this" as the first arg.

My current code looks like this:

-- Originate an outbound call
local new_session = freeswitch.Session();
new_session:originate(session, "sofia/gateway/affinity/17277762768", 60);
new_session:waitForAnswer(session);
prompt = "/home/eric/test1.wav"
freeswitch.consoleLog("INFO", "About to play prompt file " .. prompt .."\n")
new_session:streamFile(prompt)
new_session:hangup()

The scary thing about this code is that it crashed freeSwitch when I ran it.

This is the last thing I saw in the logs:

Thanks Jeff,

When I try NULL I get this:

freeswitch at internal> 2011-04-12 14:49:31.582049 [ERR] mod_lua.cpp:191 Error in originate (arg 2), ex
pected 'CoreSession *' got 'string'
stack traceback:
        [C]: in function 'originate'
        /usr/local/freeswitch/scripts/test_originate.lua:3: in main chunk

I've been digging through the source code, and I can't find where 4 args are required.  I see this in freeswitch_lua.cpp:

int Session::originate(CoreSession *a_leg_session, char *dest, int timeout)
{
        int x = CoreSession::originate(a_leg_session, dest, timeout);

        if (x) {
                setLUA(L);
        }

        return x;
}

The fourth parameter is the switch_state_handler_table reference and for most
uses(script language) you should just pass null  but I dont use lua so I
dont know the details on that.
