[asterisk-users] Someone has hacked into our system

[Kevin Keane]

Use IPTables to lock down your machine to only accept incoming connections from your local network and from the particular IPs that 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.

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
