voice source-group - Toll Fraud prevent

Cisco has a document published for toll-fraud prevention prior to 15.1(2):

http://www.cisco.com/en/US/products/sw/voicesw/ps4625/products_tech_note09186a00809dc487.shtml

I don't see how voice source-group is related to toll fraud prevention. Do you have a specific document or example citing an example that it is?

Hi.

I add a tip to what my Buddies suggested ( +5P each )
To avoid tool fraud in IOS release previous 15.1, the recommended actions are:
- configure ip access- list allowing H323 and SIP traffic to authorized ip addresses
- using direct-inward-dial on your incoming pots dial-peers and configuring a specific called number matching your DID.
Here a useful link
