There are a variety of measures you can take to insure that your PBX is safe from hackers.

Listed below are tips you can use right now to protect your business.

1. Take steps to secure your authorization codes on a permanent basis. Remind employees of the need to keep all access codes secure and change them frequently.

2. Contact your equipment vendors and ask for any and all information on the available security systems in place to detect toll fraud. They should also provide information on monitoring services available to help you quickly detect unusual usage.

3. Work closely with your PBX administrator to ensure that all of the PBX security features available are in place and are being implemented.

4. Unless needed for routine business, block outgoing international calling, 809 and 900 calling capabilities.

5. Conduct regular and routine auditing of your telecommunication systems and bills, especially just after regular vacation months and holiday seasons. It is during these times of year that PBX toll fraud most often occurs.

6. Wherever possible, limit the number of employees who are authorized to use remote access. And if possible, change pass codes and authorization codes when an employee permanently leaves the company.

7. NEVER transfer a call outside your PBX if you are unaware of the identity of the caller. Instruct employees that phone companies will never ask customers to be part of a "test" - no matter how official the caller may sound.

8. Always be alert to possible PBX abuse signs. These could include repeated calls of short duration, sudden increase in 800 usage, or unexplained changes incoming, outgoing or especially after-hours calling patterns.

9. Consider out sourcing your telecom bills to a firm that will provide bill paying and audit services on an ongoing monthly basis. You'll save money across the board and catch toll fraud at the time it happens.
