Flash call Prevention

Solve Your Flash Call Challenges

Flash calls have emerged as one of the most pressing challenges in the telco industry over the past 4 years. For MNOs, the issue stems from the lack of visibility, network QoS issues, and unclear regulatory guidelines for handling flash calls. For A2P SMS aggregators, flash calls are a nightmare, disrupting their invaluable A2P SMS revenues. On the other hand, enterprises see flash calls as a major opportunity, and they want to implement it to replace A2P SMS while cutting costs and improving UX.

As digital services expand, enterprises are constantly seeking faster, more cost-effective ways to deliver one-time passwords (OTPs) to users. While A2P SMS has long been the standard, flash calls and TTS (Text-to-Speech) calls have rapidly emerged as disruptive alternatives.

  • Flash Calls  
    • Flash calls are zero-duration voice calls terminated on an MNO network for OTP delivery. Due to their multiple benefits, they have become the #1 choice for Enterprise for OTP authentication.  
  • TTS Calls  
    • Although TTS calls are not anew technology, in the past 2 years they have been increasingly adopted by enterprises as an OTP delivery channel. Their key advantage is that the majority of market players are unable to distinguish between a normal voice call and a TTS call. This makes them the perfect choice for OTP delivery, circumventing existing measures.

Hexagon Flash Call Prevention Solution

Our Flash call Prevention solution is a cutting-edge platform designed for A2P revenue protection.

It enables mobile operators to effectively detect, manage, monetize, and mitigate flash calls in real time while safeguarding revenues and improving service quality. The solution is fully customizable and highly flexible, allowing MNOs to choose how to manage their flash by either preventing or monetizing them.

High-level benefits

  1. Revenue Protection: By detecting and mitigating flash calls, we help you prevent significant revenue leakage and enable A2P SMS traffic recovery.
  2. Enhanced Network Security: The solution protects operator networks from unauthorized flash call traffic, ensuring a more secure network environment.
  3. Real-Time Detection: Advanced analytics and AI-powered algorithms allow operators  to identify and address flash calls in real time, ensuring swift response.
  4. Dynamic Call Handling: Real-time evaluation of calling and called party behavior patterns to further minimize risk of false positives.
  5. Improved Service Quality: Reduces network congestion caused by flash call surges, maintaining consistently optimal Quality of Service (QoS).
  6. Seamless Integration: Smooth integration with the existing telecom infrastructure minimizes operational disruptions while providing immediate protection.
  7. Process Automation: The solution seamlessly orchestrates all processes in a fully integrated flash call prevention environment without delays and manual interventions.
  8. Customizable Reporting: Provides detailed reports and insights to monitor call traffic, detect trends, and fine-tune fraud management strategies.
  9. Cross Domain Analytics: Data from different domains lets you create a comprehensive analytical overview of your A2P business and traffic migration.
  10. Cost Efficiency: Preventing fraud and revenue loss while optimizing network usage allows you to cut costs, ultimately improving operational efficiency.
  11. Improved Customer Experience: By ensuring network stability and maintaining high service quality, you enable an uninterrupted UX, and customer retention.

Our Unique Edge

One of our standout features is Text-To-Speech calling prevention, available since the product’s inception. On the other hand, until Dec 2024, major vendors offered flash call blocking solutions limited to preventing zero-duration flash calls but struggling to detect and prevent TTS calls.

The main challenge associated with prevention of TTS calls is in their nature. Unlike flash calls, they are answered and considered successful, making them difficult to distinguish from regular voice traffic. Our solution overcomes this with advanced behavioral analysis and real-time detection, minimizing false positives while effectively blocking TTS-based OTP delivery.  

Monetization of Flash Calls

Our solution allows MNOs to detect, control, monetize, or mitigate flash calls in real time, protecting revenues and maintaining service quality. Highly customizable and flexible, it lets operators choose their strategy between prevention, monetization, or a hybrid approach.

Flash Call Monetization is an extension of our Flash Call Prevention product designed to help operators transform flash calls into a revenue-generating ecosystem, similar to A2P SMS monetization. Considering the global A2P SMS decline, huge market demand, and superior UX with flash calls, this product is specially tailored for Commercial Enterprises seeking scalable, cost-effective OTP delivery.
