Five Ways to Avoid Expensive VoIP Fraud Costs

Posted by Allison Boccamazzo on November 7, 2016 at 9:25 AM

At this point, we’re no longer wondering if businesses are using VoIP (the global market is slated for a 9 percent CAGR between 2016 and 2021), but how businesses can further maximize their current VoIP investments. This includes protecting one’s organization against potential security issues that inherently come with VoIP, like VoIP fraud: the unauthorized use of paid communication services charged to someone who isn't expecting it, whether that be a service provider or customer.

20161102_VoIP_Fraud_Costs.jpgWe’ve seen plenty of examples of VoIP fraud in years’ past. In 2009, for instance, a $55 million international toll fraud ring was finally busted. Overall, research has found that telco providers can lose up to $150 million per year due to fraudulent calls—a figure that some consider conservative.

With fraud on the rise (in some countries, VoIP fraud has increased by up to 40 percent in the last several years), what can be done to avoid the high costs and consequences? Here are five steps companies can take:

  1. Make good use of firewalls and access control lists (ACLs): Restrict IP addresses from which you are not expecting traffic (like traffic from specific areas or countries).

  2. Use strong passwords wherever possible: One of the most common reasons why hackers can successfully attack VoIP devices is weak extension passwords. In today’s world, a subpar password is essentially an open invitation for hackers.

  3. Restrict call routes: Avoid costly calls to known destinations that experience a high amount of fraud.

  4. Use channel limits: Ensure hackers can’t open tens, hundreds, etc. of channels at the same time.

  5. Limit the maximum call duration: Consider using a time limit—for example, two to four hours— per call.
