Sure blocking doesn't hurt, but does the help it provides exceed the
downsides

I have the same problem, once in a while.
Curiously though, it occurs on a dedicated 100Mbps switched local network.
I'm running 1.4.31 * servers.

I already have a monitor (tied into nagios, which pages me if my fraud

abilities of most of the people experiencing call fraud. The people
who know what they are doing with Unix and Asterisk are generally not

Like I said before RUBBISH.
One should just ban/block IPs that are attacking you and not let them
connect at all. Not just protect against them with fancy passwords.

I've got a dialplan that transfers all outgoing calls to a Local channel before

I did this because sometimes i'm dialling two numbers at the same time and need
to know which call is answered for billing purposes.
However, I've just noticed that billsec is always equal

We down sample it to 16bit, 8KHz, Mono. We have tried with Audacity,
