Hello,

I'm using a very ugly code to test remove_body():
request_route
{
        remove_body();
        $rd = "192.168.254.85";
        t_relay();
}

Original INVITE (with SDP):

Modified INVITE (after remove_body()):

So, remove_body() is actualy removes SDP from request but leaves Content-Type header. Why ?
