[asterisk-users] one for your filters

[Jeff LaCoursiere]

Some !@$#@@# in the Czech Republic used one of our SIP accounts to place 
four thousand calls to what appears to be a toll number in Zimbabwe last 
night.  Filter 82.150.165.5.

A more overriding problem for me is how do we know what *destinations* to 
filter so this idea of war dialing a toll number is something we can 
cutoff before it gets to our upstream provider?  Is there some collected 
list of toll prefixes that I can filter on?

Cheers,
