Balancing Cost and QoS in International Calls

The advent of high-speed 5G internet presents both challenges and opportunities for global telecom players. In an increasingly competitive market, telecom players are emphasising customer retention more than acquiring new customers. This has put the focus on the importance of Quality of Service (QoS) in international voice communication for enterprises.

High-speed communication in the form of voice, video, and multimedia requires telecom providers to guarantee a consistent level of QoS for their customers. After all, call quality has a direct impact on customer experience (CX). Majority of the consumers view CX as a major factor when selecting their telecom service provider. They are even willing to spend more for an exceptional CX. On the flip side, however, they can be proactive in switching brands after a poor experience.

That brings us to the question – what are the current challenges facing telecom providers in improving their QoS?

Let’s discuss them in the following section.

5 QoS Challenges in International Communication

Despite the advancement in business communication, voice-based communication is still relevant for customer-centric enterprises.

Here are 5 QoS-related challenges associated with international communication:

1. Real-Time Call Monitoring

As a business practice, real-time call monitoring enables organizations to improve call quality as well as measure the efficiency of customer response. For instance, call monitoring in customer support teams is used to ensure quality assurance and train new customer support executives.

Additionally, with real-time call monitoring, organisations can leverage speech analytics to improve the customer experience. However, the challenge lies in implementing a cost-efficient call monitoring solution for overall business success.

2. Fraud Detection

Fraud calls or phone spam is another major challenge in the voice communication domain. In 2022, scam victims in Singapore were duped of S$660.7 million (up from S$632 million in 2021).

In recent years, voice-based phishing (or vishing) has been deployed by cybercriminals to extract sensitive information from the victims. According to a report, in March 2022, organizations experienced the highest number of vishing attacks ever recorded, surpassing the previous record set in September 2021. Vishing is also directed at enterprises and their employees to obtain vital account-related information.

3. Integrating Multiple Communication Channels

For effective customer retention, organizations need to maintain consistency across different communication channels and touchpoints. Besides voice communication, today’s customers have access to other communication channels, including email, chat, social media, and more.

To that end, organizations need to efficiently integrate and coordinate their customer communication channels. Through proper integration, they can ensure consistent CX and avoid any duplication. By leveraging data-driven insights from these channels, enterprises can also improve their communication strategy and personalize customer interactions.

4. High Latency

A January 2021 survey found that business leaders prioritise call latency over speed. 9 out of every 10 business executives believe that business success depends more on low latency.

High call latency can easily impact call quality, thus frustrating both consumers and business executives. More profoundly, it can cause delays in voice communication and adversely impact customer experience.

To improve latency-related challenges, organizations must consider the following measures:

Upgrading their existing call infrastructure and communication devices
Improving their call routing system
Choosing the right telecom service provider

5. Cost Management

The latest telecom statistics stress that 77% of consumers believe a phone call is the best way to get answers to their queries. Also, 65% of consumers prefer to contact a business by phone.

With the increasing adoption of voice communication tools, companies are incurring more costs with their legacy communication equipment and tools.

Here are some of the cost-related challenges that enterprises face:

Upgrading and replacing their communication equipment and hardware devices
Increased time and money spent by enterprises in addressing customer concerns and queries
A shortage of skilled communication specialists adds to an organization’s hiring and training costs

The Must-Have Features of a Modern SMS Firewall

Across industries, SMS marketing is eventually outpacing several other mediums to become the most trusted customer communication channel worldwide. That’s why enterprises are increasingly relying on SMS firewall solutions to bolster their marketing abilities allowing them to bring in leads through messaging.

However, the dilemma for leaders lies in selecting the right SMS firewall system. Most leaders are unaware of the features they must evaluate before investing in an SMS firewall system.

To make it easier, this article looks at the top 5 features that a modern SMS firewall must guarantee to help enterprises succeed in their SMS-driven customer approaches.

Proactive Security

The number one feature that an SMS firewall must have today is proactive security analysis and threat mitigation in the SMS traffic an organization handles daily. From common spam texts to intelligent text phishing or fraudulent routing, the landscape of threats that today’s businesses face with their SMS ecosystem is enormous. For an SMS firewall system, they must ensure a safe and spam-free environment for both end-users as well as mobile operators.

In the past, the security of SMS firewall systems had to be managed manually, which necessitated the hiring of dedicated security engineers to cater to SMS traffic alone. Today, however, there are AI and ML-powered SMS firewall solutions, like the Armour SMS Firewall, that offer 360-degree network protection for SMS traffic to and from an organization. This helps prevent fraud and stop revenue leakage, ultimately contributing to rising profitability.

Global Connectivity

Modern SMS firewalls must not be restricted in usage support for local markets. Businesses with ambitious expansion plans internationally will find globally supported SMS firewall solutions to be a core asset in their market penetration efforts. SMS is a trusted communication medium for most consumers, offering brands an opportunity to expand into new markets through seamless SMS marketing campaigns.

An SMS firewall provides a critical digital environment and assets to ensure that the end-user gets the right message at the right time — thus, leading to better conversions.

Better A2P Monetization

It is estimated that the global market for A2P messaging will exceed USD 72.8 billion by 2025. Several new internet-driven businesses are increasingly leveraging A2P as an additional or even their primary revenue channel.

An SMS firewall must be able to offer uninterrupted support and adaptability to new business models that leverage the underlying A2P messaging service. From seamless integration with multiple systems involved in completing the revenue cycle to enabling efficient reporting, the areas of interest are immense.

Flexible Rules Engine

Consumers flock to new devices running different operating systems every now and then. It is impossible for businesses to smoothly manage their SMS marketing initiatives that are heavily dependent on end-user device characteristics.

An SMS firewall should work independently and offer flexibility in rule customization, new policy implementation, and device-agnostic SMS traffic management. Avoid delays in software or hardware updates on end-user devices to stay ahead of the competition. Moreover, the SMS firewall must support all standard rules and best practices that have been proven to be effective in SMS-driven marketing worldwide.

Ease of Use

Features offered by a modern SMS firewall become irrelevant if the user isn’t able to leverage it easily to drive campaigns. The usability of the SMS firewall system is a huge factor that should be evaluated before investing.

Since an SMS firewall forms a critical part of marketing, businesses should integrate the SMS firewall system into their strategies. Once done, they can deploy new configurations on the go from easy-to-use dashboards rather than manual and obsolete interfaces.

The Bottom Line

Protecting subscribers and telecom operators from fraud while enabling better revenue potential in existing channels are perhaps the two most important features from the list we have discussed today. Nevertheless, enterprises must strive towards investing in solutions that offer as many of these top five features as possible.

The various aspects a call anti-fraud solution must cover

Security breaches and fraud are not new in the telecom industry. As technology gets sophisticated, hackers and fraudsters too get smarter. They are on the constant lookout for vulnerabilities and are relentless in testing firewalls for cracks and weaknesses. Scammers and fraudsters attack, take their profits, and leave before they can be stopped.

In 2021, total global telecom revenues stood at approximately USD 1.8 Trillion. But the amount of telecom revenue loss due to fraud stood at $39.89 Billion. Fraud losses increased by 28% or approximately USD 11.6 Billion between 2019 and 2021.

Voice fraud is one of the top inter-carrier fraud cases. Voice fraud burdens subscribers with huge bills and affects MNOs and their residential and commercial subscribers. Some of the common types of voice fraud are IRSF (International Revenue Share Fraud), False Answer Supervision (FAS), Number Hijacking, Interconnect bypass, and Roaming Fraud. Call Forwarding Fraud, Wangiri fraud (a Japanese term for one (ring) and cut), SIM Box fraud, and PBX hacking are some of the other kinds of voice fraud that are making the chamber of horrors for telecom operators.

IRSF (International Revenue Share Fraud)

IRSF fraud assumes a backdoor revenue-sharing agreement between an IPRS or a communications provider. The fraudster manipulates the telephone service and receives compensation for the traffic. IRSF fraud generates anything between $4 and $6.1 billion in damages.

Standard monitoring solutions fail to identify this kind of fraud easily as it is very hard to sift through large volumes of daily traffic to identify anomalies.

False Answer Supervision (FAS)

False Answer Supervision (FAS) can be of two types. The first kind is the Early Answer fraud where a call connection takes place before the subscriber answers the phone. The second kind is the Late Disconnect fraud where the call remains active and the billing clocks even after the subscriber hangs up.

Number hijacking is also another kind of FAS fraud. Here the fraudulent operator keeps the customer waiting for the connections for as long as possible or until the maximum call timer runs out.

Interconnect bypass or SIM Boxing

Interconnect bypass fraud allows fraudulent operators to profit from the spread between low retail prices for on-net and off-net calls and higher international interconnect rates. This fraud enables the unauthorized insertion of traffic onto another carrier’s network. It is also called SIM Boxing.

The fraudulent party replaces the expensive international interconnect with a cheaper, practically free, routing channel and pinches the difference.

Wangari Fraud

Wangari fraud is a call-back scam. Wangari is a Japanese term that means one ring and cut. The fraudsters give a missed call to unsuspecting subscribers to call back to fraudulent premium numbers. CSPs incur direct and indirect losses because of Wangari fraud.

However, the lack of timely threat intelligence and the lack of a platform to exchange data in real-time impede operator capabilities to identify Wangari Fraud proactively.

PBX hacking

PBX and VoIP hacking is when fraudsters hack into telecom networks and pump up significant traffic levels for an IPRS. PBX hacking is a common and well-known form of telecom fraud and can lead to enormous revenue losses. According to the Communications Fraud Control Association (CFCA), in 2019 PBX hacking was the number 1 telecom fraud method, causing a global fraud loss of $3.64 billion.

CDR-based anti-fraud systems cannot break active calls and hence are not well-suited to prevent PBX hacking. They also perform poorly with traffic disguised with statistical patterns. PBX attacks can last for hours and go undetected in the absence of the right anti-fraud systems.

Grey Calls

Grey routes have been giving telecom operators sleepless nights for decades. Grey calling routes bypass licensed carriers by terminating international calls onto domestic telecom networks using unlicensed and illegal telecom setups.

The illegal operators host their equipment at places where their calls can reach multiple cell sites for the calls to get widely dispersed. They also employ multiple SIM boxes, rotate SIM cards, manipulate calling patterns, etc. to outfox traditional fraud detection systems.

SIM Box fraud is illegal since the operators running these setups do not have the required government licenses. These networks not only lead to huge revenue losses but can also impact national security because these routes can be easily exploited by terrorists and anti-national elements.

The solution

Traditional fraud detection systems often do not provide the depth of scanning needed to combat the growing sophistication of telecom hackers and fraudulent agents. Telcos now need to be able to proactively prevent potential fraud by developing their capability to identify suspicious inbound and outbound traffic streams based on behavioural patterns and anomalous traffic.

Fraud detection systems that use technologies such as AI and ML make the telecom security perimeter more airtight. AI-ML-powered detection systems help detect fraud calls in real-time based on various parameters.

Parameters such as behavioural analysis (from a single Calling Line Identification), call volume, the time gap between two calls, number length, adjacent number checking, call distribution working and after working hours, and the number of unique destination numbers in a given period and consecutive attempt gap of a failed call attempt are some such areas to configure.

The right anti-fraud solution leverages machine learning algorithms for faster and proactive anomaly detection and navigating challenges like Interconnect bypass or SIM Boxing.

These solutions protect the subscribers from fraud, quality fluctuation, and surprise bills and can be fully configurable to meet specific business needs. AI and Machine Learning algorithms make proactive and continuous scanning of traffic routes possible and easily point to anomalous traffic.

In Conclusion

Voice fraud has been and shall continue to remain a lucrative criminal activity. As technologies advance, so does hacker and fraudster sophistication. A comprehensive anti-fraud detection system thus emerges as a critical investment to secure networks and revenue. By strengthening the security perimeter and establishing powerful firewalls driven by AI and ML, telecom providers can minimize fraud risks and prevent revenue and reputation leaks.
