DoT Asks Telecom Operators To Expedite Trials For Caller ID Display

The department of telecommunications (DoT) has reportedly asked the telecom operators to expedite trials for the implementation of the caller ID display system, a move aimed at curbing the rising incidents of cyber fraud.

A Moneycontrol report, citing sources, said that the caller name presentation (CNAP) will be rolled out in phases in the coming months.

The DoT has directed telecom operators to finish inter-operator CNAP trials and submit the report by April 18.

Sources told Moneycontrol that trials are undergoing in Haryana and Maharashtra. While Vodafone Idea is looking to begin its trials this week under the telecom department’s supervision, Reliance Jio and Bharti Airtel have completed their tests.

At first, the services will be rolled out to 4G and 5G users, while 2G users may experience a delay in access due to the significant investment required for network upgrades.

Airtel and Vi have both collaborated with Nokia for the nationwide deployment of the IP Multimedia Subsystem (IMS), a technology that supports CNAP and related analytics such as spam detection and international long-distance (ILD) filtering, the report said.

“Telcos have taken solutions from players like Nokia, including analytics for spam, CNAP and ILD. It is a combined solution, which is live on both Airtel and Vodafone Idea’s networks,” a source told Moneycontrol.

Notably, Reliance Jio has developed its own CNAP technology-in house as its entire subscriber base is on 4G and 5G.

Given the limitation of legacy 2G switches that can’t support the new technology, Airtel and Vi have raised the issue with the Telecom Regulatory Authority of India (TRAI) and the DoT. The limitations are coming in the way of new service availability for 2G phone users.

It is pertinent to note that full scale implementation of CNAP relies on government-mandated sharing of caller databases among telecom operators, it said.

The development comes after the DoT in January asked telecom operators to introduce caller

At that time, the telco industry raised concerns over user’s privacy with the rollout of the service.

Besides, DoT is also planning soon to block international spoofed calls, as reported in October last year. The system will be rolled out to keep an eye on curbing the growing number of incidents involving fake threats of mobile disconnection and arrests, and impersonation of government officials, said DoT.

In an effort towards curbing spam calls, the Telecom Regulatory Authority of India (TRAI) is also looking to launch an updated version of its to provide some relief to smartphone users.

It was reported in October last year that TRAI will likely finalise tighter and updated regulations on curbing spam calls and messages by January, after it directed telecom operators to for spamming end users.
