Of course, we block the traffic with a REJECT rule.

But since we have configured 120 seconds as disable_timeout, I could
expect a short period of blocking but after that it should run again
for at least 120 seconds. But from what we see, this does not happen.

Oh, and we tested the disabling and enabling via kamctl before, but as
far as I remember, while disabling still worked, Kamailio crashed
reproducably when enabling an rtpengine again.
