TRAI Tightens Spam-Call Rules for Truecaller and Other Apps
TRAI has changed the rules for apps that manage phone calls.
These apps include services such as Truecaller.
They can no longer automatically flag or block calls from numbers beginning with 1600 or 140.
They may do so only if they share spam information with telecom companies’ DLT platform.
TRAI has also created new rules for robocalls.
Robocalls are calls made automatically rather than by a person.
The regulator also changed rules for commercial communications.
The goal of the changes is to control how spam information and commercial calls are managed.
TRAI has barred call management apps from flagging or blocking calls from 1600 and 140 number series.
Apps may handle those calls only if they share spam data with telecom operators’ DLT platform.
The changes affect apps such as Truecaller.
TRAI has introduced additional rules for robocalls.
The regulator has also tightened rules governing commercial communications.
