Use IPTables to lock down your machine to only accept incoming

you are expecting connections from (such as your SIP trunk, maybe).
That is of course assuming that these calls are made by SIP.
Don't forget to also change all the passwords.
good point - someone can easily just dial in a pots line locally and
dial out another one making a long distance call, assuming the dial plan
allows this.
it doesn't have to be sip involved in any part of the problem.

*Subject:* [asterisk-users] Someone has hacked into our system
Someone has hacked into our system and is making calls overseas.
How can I:
1. Find out the where the calls are originating from?
2. Block all calls that are not authorized?
Our system is in the USA.
Only calls from inside our LAN are allowed.
Thank you,
Gary Kuznitz
