[Spce-user] Disable calls after midnight...

Hi Lorenzo, the attacks are not to our servers. It's more on the client's
PBXes etc which we don't control which is the issue. Even with Fraud
Protection and education to end users, there's still times when losses are
incurred and are difficult to get back. It's more time consuming to even
find out what happened and push the blame here and there.

Considering that it's always in the midnights/early hours etc where no one
is actively monitoring systems that things occur, we want to just ban the
call outs say to foreign DIDs for the clients who agree.

We thought about updating say iptables at night to stop sip traffic for
example, but that would send alarm bells ringing on monitored systems so
not good.
ᐧ

If you can direct me in someway of how to start this off, we can try it
out. One personal failure is that I'm not proficient enough in Kamailio to
hack it. I know it's not a very good option to "hard code" it in but it'll
be good if we can manage it via another MYSQL table or something.

Thanks

Martin
