[asterisk-biz] Mailing lists or other resources to stay on top of toll-fraud prevention

[Stephen Davies]

Hi,

I'm looking for suggestions of mailing lists or other resources that I can
use to stay on top of the latest toll-fraud schemes.

Also, "best practices" to harden Asterisk systems against toll-fraud.

I'm hoping for a check-list of items, a source of an updated black-list of
numbers.  (Is a RBL type service too much to hope for?), and similar
resources.

Thanks,
Steve
