Telecom Wholesale Fraud

Stopping fraudulent traffic at the international wholesale carrier level

Telecom Wholesale’s prevalent fraud scenario encompasses different types of Fraud

According to some industry reports, fraudulent traffic is projected to cost the international wholesale carrier industry $17 billion annually. The ever-changing techniques deployed are making it more difficult to catch fraudulent partner carriers. While most carriers can identify at most times fraudulent patterns on their networks, contractual service agreements and fear of incorrectly blocking legitimate traffic can make the elimination of fraudulent traffic complex. The Mobileum wholesale fraud module allows carriers to gain comprehensive visibility of their network traffic, allowing them to identify fraudulent attacks and address them quickly with the highest level of accuracy in the market.

Advanced Protection against False Answer Supervision (FAS)

False Answer Supervision (FAS) most times occurs when there is a lack of synchronization between a VoIP leg and PSTN leg of the call on a VoIP-to-PSTN gateway. When the call reaches the gateway from the VoIP network the gateway tries to establish a connection with the called number but, most likely due to an incorrect configuration, it cannot detect the states of the call, which are returned by the PSTN network. These states are: "called party ringing", "called party connected". Therefore, the gateway forces the answer state which normally occurs immediately after the arrival of the call from the VoIP network or after a few seconds. The problem is that the gateway answers the call (which starts the billing) according to its own settings, but not according to the actual state of the call.

Proactive protection against Call Stretching with Test Call Generator

Call Stretching is an inter-carrier fraud type that occurs on international voice services, where a fraudulent carrier or transit provider plays a recording with a fragment of a conversation during the time of the call. After a few minutes, the call is terminated on the B-side but kept on hold on the A-side with the recorded audio being played back repeatedly. As a result, the billed time of the call is longer than the time for which the called party was on the line. With Mobileum Test Call Generator and advanced Fraud Management System, CSPs can test these scenarios. Mobileum smart detection performs an automated comparison of the B channel voice to text conversation against the original recording to more quickly detect cases of fraud and stop being charged for illegal calls.

Traffic Pumping and the settlement of “ghost” caller

Traffic pumping, also known as access stimulation, is a dubious practice by which some local exchange telephone carriers in rural areas of the United States inflate the volume of incoming calls to their networks to profit from the greatly increased inter-carrier compensation fees. In order to spur competition for Incumbent Local Exchange Carriers (ILECs), the FCC allows rural Competitive Local Exchange Carriers (CLECs) and Incumbent Local Exchange Carriers (ILECs) to charge high terminating access charges for completing calls they accept from Inter-Exchange Carriers (IXCs). RAID wholesale fraud detection includes specific validations and controls that detect traffic pumping patterns in order to protect against revenue loss during inter-carrier settlement.

Wholesale SIP trunking, a scalable fraud door

Session Initiation Protocol (SIP) Trunking is a way of providing telephone calls using data rather than fixed lines. SIP is the natural replacement for fixed lines and in addition, offers greater flexibility and resilience whilst being at a lower price point. Fraudulent wholesale SIP trunking is an emerging fraud type where fraudsters make money by selling wholesale trunking services or using stolen credentials to terminate the calls. A key pattern identified on this type of fraud is the huge number of apparently random calls to destinations such as Asian countries, that are not specifically high cost and are mostly dissimulated as residential numbers, can get below the radar creating a huge impact on the revenue.

Mobile Termination Rate (MTR) an emerging menace

Mobile network operators are now able to apply higher termination rates to non-EU incoming traffic. In these situations and when there is a considerable gap between the termination rates, the risk of exposure to Mobile Termination Rate (MTR) Arbitrage (also know as tromboning), is very high and can cause a significant impact to your network. In order to terminate the calls at lower costs, some carriers that are intended to pay a high MTR recreate the traffic in order to pay a lower MTR. RAID provides you with detailed information on how traffic originating from risky countries, suspicious ranges of numbers and unusually high or continuous low volumes in your network.

Top 6 threats of Wholesale Fraud

Degraded QoE
Wholesale carriers plan a major role in ensure seamless call connectivity through Inter-operator network connections. The rogue wholesale carriers significantly impact the call quality leading of huge number of call drops.
High Revenue Loss
False Answers, Call stretching, illegal call hijacking, short stopping of calls, SIP Trunking etc. are just few types of Wholesale fraud which not only impact the CSPs revenue but also leads to negative revenue for the wholesale carriers.
Low Brand Value
Operators expect their Wholesale partners to facilitate improved and more convenient communications. Nevertheless, when the service quality degrades, and customers don’t get services as expected, it impacts the CSP’s brand value.
Degraded Customer Experience
Wholesale fraud not only impacts CSPs’ bottom lines—it also impacts CSPs’ relationships with their customers. Degraded voice quality and latency issues caused by fraudulent carriers negatively impact the customer experience, which can eventually cause customers to lose faith in their CSP and even defect to another provider.
Increase cost of Fraud Prevention
The use of fraudulent traffic by organized crime to raise and distribute funds highlights how important it is that international carriers work to reduce fraud as the impact goes beyond the carriers’ profit and loss. They now invest heavily on dedicated fraud management full time employees (FTE) who are not linked to commercial performance but are critical to ensuring that they have clear incentives to reduce fraudulent traffic.
Settlement and Bill Disputes
Fraudulent carriers generate illegal traffic and in turn are able to generate high volume invoices which they charge to their CSP partners. Such massive bills leads interconnect partner disputes, eventually leading to delays in bill payments and settlements.
