Check your kamailio.cfg. In the "default" config OPTIONS get this response due 
to:
        if ($rU==$null)
        {
                # request with no Username in RURI
                sl_send_reply("484","Address Incomplete");
                exit;
        }

You'll have to response with a 200 yourself, eg:

route[REQINIT]{
...
        if($si=="192.168.182.24" && is_method("OPTIONS"))
        {
                sl_send_reply("200","Up and running");
                exit;
        }

It's up to you to decide to which OPTIONS requests to response with what code.
