Responding to toll fraud attempts
If your phone system has been the target of toll fraud attempts, you can do the following:
• | Report Caller ID numbers and called numbers of fraudulent calls to your long distance carrier. Sometimes carriers can block certain numbers from calling you. |
• | Report excessive toll fraud to your local FBI office. Note, however, that the FBI does not usually get involved with toll fraud unless losses are substantial. |
You can also use the information from previous toll fraud attempts to make your system even more secure. For example, you can add any numbers being called during toll fraud to the list of numbers prevented with dialing permissions. If fraudulent calls have been made to a particular few countries that are not otherwise called, disallow dialing those country codes (011xxx).
