[SR-Users] How to limit maximum number of calls

[Austin Einter]

Hi
I did change kamailio.cfg as below and getting some error.

*//Loaded dialog module*
*loadmodule "dialog.so"*

My route block looks as below.

*# Main SIP request routing logic
# - processing of any incoming SIP request starts with this route
route {*
*        # per request initial checks
        route(REQINIT);
        setflag(FLT_NATS);
        # NAT detection
        route(NAT);*

*        # handle requests within SIP dialogs
        route(WITHINDLG);*

*        if (is_method("INVITE"))
        {
                if($DLG_count > 1)
                {
                        sl_send_reply("503","RESOURCE UNAVAILABLE");
                        exit;
                }
        }
*
I added the if block shown in red color.

When I start the kamailio proxy I get below error.

It looks , dialog module facing problem during initialization.

I am bit new to this, not getting any clue . Kindly let me know whats going
wrong.

Thanks
Austin
