Several mobile phone companies have even suggested using the same blockchain-based system used for text messaging to phone calls, which suggests that the industry is seriously considering adopting AI-led interventions to solve the problem of pesky calls. Blockchain is emerging as a game-changing technology that can solve all the problems plaguing the telecommunications sector, ushering in a new era of efficiency, security, and transparency. This technology is revolutionising telecommunications because it has the ability to provide full automation of financial settlement and fraud prevention to KYC procedures for enrolling consumers.


“A technology intervention that studies call patterns like duration of calls and the frequency of outgoing calls is a solution that telcos will need to deploy…” by Faisal Kawoosa, Techrc.


Tecols Mull deploying AI to check spam calls

According to an anonymous executive in the business, “several telcos have started tinkering with the notion of using AI/ML (machine learning) for solving the issue of pesky calls,” although these efforts are still in the early stages.

This action is in reaction to the widespread use of menacing phone calls and text messages to trick mobile customers into making large financial transactions for fraudulent purposes. The AI-powered system aims to identify the characteristics of these spam calls and notify the relevant network providers so they may take appropriate action. Outgoing call duration, call frequency, and other such metrics may reveal patterns. The use of artificial intelligence and machine learning (ML) to eliminate spam calls has received much attention, but it is still nascent.

A recent poll by LocalCircles found that mobile users throughout the country are increasingly being harassed by scammers who use their phones to steal hundreds of crores of rupees. According to the poll, 66% of mobile users in India receive at least 3 annoying calls every day, the vast majority of which come from individual mobile numbers.


The telecoms want to implement AI/ML-driven systems to detect spam calls. Technology might help operators combat spam and fraud calls by examining the duration and frequency of such calls. A large number of brief calls are made to unfamiliar numbers every day. An article in ‘IndiaTimes’ recommends that cell service providers consider using AI technologies to detect suspicious caller behaviour and block them.

According to the article in Economics Times, which cites anonymous telecommunications company officials, the next stage will be for the companies to apply the principles of distributed ledger technology (DLT) to phone calls. The frequency of such calls can be decreased by using a DLT-based verification procedure in conjunction with an AI-led spam detection system.

In order to combat spam, the Telecom Regulatory Authority of India (Trai) has mandated the use of the DLT by all service providers. As a result, businesses whose primary mode of communication is mass messages must first register on the DLT network.

The Telecom Regulatory Authority of India (TRAI) has required all operators to deploy distributed ledger technology (DLT), a blockchain-based solution, and the deployment of distributed ledger technology (DLT), a blockchain-based solution, by all operators in order to control spam messages.

The DLT Platform requires genuine marketers and telemarketing organisations to register themselves, the headers (the code one sees when receiving messages from a band), and the message templates. Under this system, messages with valid headers and matching templates may only be sent by authorised senders.

The CLI (Callee line Identification) is the number that appears briefly on a receiver’s screen when it is not saved on their contact list.


Initiative by TRAI

In a meeting conducted on 17th February 2023, TRAI discussed the action plan to improve the quality of service (QoS) and review the current QoS for 5G services and unsolicited commercial communications.

In 2022, TRAI released a consultation paper on the mandatory implementation of  The Telecom Industry Association of India (Trai) has taken on the problem of pesky or spam calls Calling name Presentation (CNAP) in telecom networks which are made to display the names of the caller on the receiver’s screen when their call connects. However, there is so positive result of the same



Even though we have rules and regulations to deal with spam calls and texts, it can be seen that the number of customer complaints has increased day by day. Now unwanted contact is a common topic of conversation. The result of a small survey by LocalCircles revealed that 45% of the people get, on average, 3-5 pesky calls daily, while 16 % claimed to get 6-10 such calls daily, It’s the need of the hour to take some initiatives in order to safeguard the interest of the public.[2]

It is evident that customers are often left in a vulnerable position due to spam calls. Although many telecommunications companies have introduced solutions to reduce and trace such calls, the burden still falls heavily on the customer. Customers should be made aware of the importance of data security and given the tools they need to safeguard better their own information and the information of others with whom they interact. In order to effectively combat these actions and safeguard important data and information, telecommunications providers, consumers, and regulatory organisations must work together.
