Toll Fraud Prevention

[Tim Smith]

Hi Guys,

Does anyone know of any good resources or lists regarding this.

Specifically, wanted to come up with a list of country / area codes to block possibly.

Have done a bit of looking on the web but found mostly older stuff.

Also had a look at all the standard cisco fare for preventing toll fraud. Does anyone have any fresh advice or ideas on the subject?

Cheers,

Tim.

Calling Search Spaces and Route Patterns are basic for Toll fraud prevention.

Normally you restrict International Numbers and 900 numbers.

This is the standard list that I use in all of my IPT installations. Hope this helps out. Let me know if you need any more detailed help.
