When it comes to least cost routing, VoIP protection, believe it or not, is a pretty big deal. VoIP is just as vulnerable to attack as any other IP communications medium and so fraud in the VoIP industry is, unfortunately, something that often goes unnoticed.

TransNexus’ (News - Alert) solution to VoIP security is least cost routing. By focusing on trends and patterns, a smart monitoring service like least cost routing can see where there is an unusual spike in calls to a specific area, and their solution, the NexOSS, can put a block on the route until the matter is further investigated.

NexOSS saves VoIP service providers time and money with intelligent routing solutions. This includes no-loss least cost routing that supports up to 100,000 translations, as well as routing by quality-of-service, time of day, day of week, and customer specific routing. 

Voice over IP (VoIP) is susceptible to many of the threats afflicting traditional voice services but the ease of setting up a VoIP hosting service, lax international regulation, co-existence with other IP protocols, anonymity and lack of location transparency all contribute to fraud and security issues.

Potential security risks to VoIP are denial of service, viruses and spamming, with caller ID spoofing emerging as a useful tool for identity theft and phishing scams as many businesses have Internet telephony equipment that can be set up to make any number appear on the caller ID system.

The NexOSS 5.11.2 adds a new fraud scoring feature, which can be a powerful tool to help VoIP service providers avoid VoIP fraud. According to TransNexus, Each call is rated using the fraud risk for the destination dial code. Calls to high-risk destination get a high fraud score while calls to low risk destinations get a low fraud score.

By using this scoring technique, each customer can be assigned a single fraud score trigger threshold for all breakouts. The new fraud scoring feature aligns fraud detection more closely with real world economic risk and simplifies fraud detection management.

A brief search on the Internet will reveal many examples where companies have been defrauded, as well as tools to probe VoIP systems to identify vulnerabilities. With TransNexus’ latest release of their NexOSS solution, there is peace of mind when it comes to protection against VoIP fraud.
