The Toll of Flash Callson Networks and MNOs

Network Congestion

Flash calls can congest network resources, leading to impaired service quality and disruptions for legitimate calls.

Revenue Leakage Threat

Flash calls pose a significant revenue leakage threat, especially with increased international A2P prices.

Threats to Privacy

Flash calls involve attempts to obtain sensitive data from users, which may threaten user privacy and security.

Zero-Duration Calls

Zero-duration calls may not even generate CDRs for MNO billing systems, which aggravates revenue loss concerns.

How This Can DisruptYour Business Operations

Operational Impact

Handling unwanted calls makes operations complex. Besides financial concerns, managing flash calls consumes time and resources.

Revenue Loss

Flash calls pose a significant risk of revenue loss for MNOs, especially in markets where termination fees are zero-rated.

Dexatel’s ComprehensiveFlash Call Detection System

We employ a multi-faceted approach to accurately detect and prevent flash calls.

Network Monitoring and Analysis

Flash calls show distinct patterns, which is different from normal call behavior. Using advanced analytics and machine learning algorithms, Mobile Network Operators monitor call patterns for anomalies. Caller behavior profiling helps identify numbers frequently initiating short-duration calls, which are then flagged for further analysis.

Firewall Rules and Filters

Implementing firewall rules and filters involves setting rate limits on the number of calls per number within a timeframe. Our solution offers customizable filters to blacklist numbers generating flash calls while whitelisting trusted numbers. Content analysis capabilities allow the firewall to identify potential flash call signatures.

Penetration Testing

Regular penetration testing is performed to identify network vulnerabilities exploitable by flash calls. Dexatel conducts simulated scenarios to assess network resilience and the efficacy of detection strategies. Penetration testing helps refine response procedures to ensure swift and effective action in the event of flash call incidents.

Got Questions?We Have Answers

Why Do I Need To Detect Flash Calls?

Detecting flash calls is necessary for MNOs to protect their revenue streams, maintain service quality, and uphold customer trust by preventing spam and fraudulent calls from reaching their subscribers.

What is Penetration Testing?

Penetration testing is a cybersecurity practice involving simulated attacks on a computer system or network to identify vulnerabilities that could be exploited by malicious actors, such as those behind flash calls.

What Are Firewall Rules?

Firewall rules are policies or settings configured within a firewall to regulate the flow of network traffic and control access to or from a network. In the context of detecting flash calls, firewall rules can be used to block suspicious or malicious call traffic.

How Does Network Monitoring Help Detect Flash Calls?

Network monitoring involves continuously analyzing network traffic patterns and behaviors to identify anomalies indicative of flash calls. By monitoring call patterns, MNOs can detect and flag suspicious activities for further investigation.
