Describe the bug

REGISTER sip:10.27.136.168:5060;transport=UDP SIP/2.0

For some reason this obviously broken Contact not get reported by

   $var(err_id) = sipmsg_validate("shmrftc");
    if ($var(err_id) < 0) {
        xlog("L_INFO", "pt=[$time(%b %d %T):$Tsm], [VALIDATE] node=[lb1]. Invalid SIP request: [$var(err_id)] (M=$rm ID=$ci RU=$ru F=$fu T=$tu CS=$cs SRC=$socket_in(proto):$si:$sp DST=$du)\n");
        send_reply(400, "Invalid SIP request");
        exit;
    }

To Reproduce

Expected behavior

We expect 400 responce to this message. In reality this gets reported only at save time in log
