Thanks. I'm still a novice at hardening my asterisk system. I never had any trouble until recently. I think someone found my DID number and that's what the source of the hack is, not actually through my asterisk server. But the VOIP provider is convinced that's how it happened. But wouldn't the /var/log/asterisk/cdr-cvs/Master.csv file show which extension they used. And I'm not seeing any of the illegal calls being logged with an extension in my asterisk sip.conf file. They are logged with an IP address...which again I don't know how to interpret other than running a whois and seeing that alot of them originate from Amsterdam.

I wouldn't really call them a terrorist if there was nothing stopping them from dialing through your system. Oppertunist, unscrupulous perhaps. Terrorists generally try to cause mass destruction or panic in a large group of people. At any rate, it isn't hard. You could use vm_authenticate, which will authenticate based on the voice mail password, or just plain authenticate. You should also do some pattern matching on the numbers that are input, before the call is sent back out. Do you really need to call anywhere in the world, or just certain places? You could restrict the destinations, which might save you if someone figures your password out. - -Tim Frank Griffith wrote: > I have a DID with a VOIP provider which has worked pretty well.
