VoIP Fraud: What You Need to Know
VoIP has had to put up a fight as a credible technology, especially in the business world, since its inception. The thought of putting control of voice quality and experience over an Internet connection scared many leaders – to say the least. And while networks have gotten stronger and connections better, there still remains a fear around security and the different scenarios that could go wrong with VoIP.
While some, if not most, of those fears are irrational and irrelevant today, there is one that remains very valid, and should never be ignored.
Using the paid communication services of someone else – so they are unexpectedly charged for the usage – service provider or customer – is how the fraud is taking place. And it’s costing businesses a pretty penny.
According to another blog post by the company, “Telco providers can lose up to $150 million per year due to fraudulent calls” and this is a figure that some even consider conservative.
So what are things that can be done to avoid VoIP fraud? Passwords. They are still the most important thing protecting you. As time passes we need to strengthen and make these harder to crack. It goes without saying that you should never make all your passwords the same and you should always be using things like symbols, numbers and lower and uppercase letters.
You should also focus on using firewalls and access control lists that will restrict IP addresses and even configure your server to protect from SIP digest leaks.
There is also a way to put limit channels so hackers can’t open a bunch at a time and even a way to limit the time spent on each call.
Finally, you’ll want to find a fraud detection service that offers things like advanced monitoring, reporting, analytics, alerts – the whole nine yards when it comes to visibility of what’s happening with your VoIP traffic.
