What is a CNAP feature?

About CNAP:

The feature would provide an individual with information about the calling party (similar to ‘Truecaller’ and ‘Bharat Caller ID & Anti-Spam’).
The idea is to ensure that telephone subscribers are able to make an informed choice about incoming calls and curb harassment by unknown or spam callers.

What is its purpose?

Existing technologies present the number of the calling entity on the potential receiver’s handset.
Since subscribers are not given the name and identity of the caller, they sometimes choose not to answer them believing it could be unsolicited commercial communication from unregistered telemarketers. This could lead to even genuine calls being unanswered.
Additionally, there have been rising concerns about robocalls (calls made automatically using IT-enabled systems with a pre-recorded voice), spam calls and fraudulent calls.
Truecaller’s ‘2021 Global Spam and Scam Report’ revealed that the average number of spam calls per user each month in India, stood at 16.8 while total spam volumes received by its users were in excess of 3.8 billion calls in October alone.

Q1) What is TRAI?

The Telecom Regulatory Authority of India (TRAI) is a statutory body established on 20th February 1997 by an Act of Parliament, called the Telecom Regulatory Authority of India Act, 1997, to regulate telecom services, including fixation/revision of tariffs for telecom services which were earlier vested in the Central Government.
