Michelle Patterson is excited with the new technologies that are threatening to change the way we stay in touch and communicate, particular in business. She works with companies that are introducing these technologies to make understanding them easy for regular people.
VoIP fraud can be extremely damaging for any business (small or big) and you can fall prey to malicious programs that breach the security of your communication network. You cannot let the guard down just because you have a new firewall protection installed on your network – do not forget, the hackers find new ways to penetrate your communication network. Prior to learning about reducing VoIP fraud damage, you must learn about the common ways through which you can suffer VoIP attacks. In this article, we will try to learn about the top 5 ways to reduce VoIP fraud damage.
1. Give limited access to routes for every user – It is very important to limit the fraud areas or the high price to only those customers who would actually need it. Often it has been observed that customers do not need international termination – it is better not to extend this service to all customers. Do not offer international dialing plans to all your customers; give it to those who really need the service. Give access to routes only when they send you a request for the same. It is also equally important that you block the premium rate numbers. It is imperative that you do not offer the fraud toll or high cost numbers. Blocking the premium rate numbers is extremely easy and you will have to provide this safeguard to your customers. Offer these numbers on receiving special requests.
2. Stop routing numbers that are without a fixed rate – Calls, which do not have a fixed or defined cost, must be blocked. You will have to block all the calls that do not have the defined rates. Even though this sounds to be the most plausible path but the strange fact is that not many people use this until and unless they receive the ULC or underlying carrier invoice. The number of simultaneous calls should also be limited so that you are able to restrict the number of calls or the maximum number of channels to be used simultaneously. You can monitor your requirement of the number of channel usage by finding out the average monthly usage. Thus, call flooding can be easily prevented in the event of a breach.
3. Drop the calls after a fixed time period – You will need to set the call time limit as this would work in tandem with the limitations on the number of channels. Thus, any fraudulent call would not last longer as it would be automatically be cut after a predefined time period. Hackers won’t be able to make long calls that last for hours and you will be able to reduce the severity of the attacks. You can even opt for the prepaid billing or the postpaid that have limited quota where the service can be terminated in the event of a breach. The best thing about the postpaid or prepaid connection with termination facility is that you will be able to automatically terminate after a certain time period.
4. You can opt for the Geo-IP restrictions – Well, this is a bit contentious but if you think that the threats are coming from a particular location then you an even block the IPs from which the calls are coming. Thus, if you are not selling your products or services to china then you can even block the IPs belonging to the country.
5 Set alarms for the unusual activities – You can put in place a system that tracks the traffic activity and in case anything unusual is noted, you are immediately sent a notification. This will help you to keep track of any unnatural increase in the traffic volume and reduce the VoIP fraud damage.
