Trai tells telecom operators to block pesky calls, SMSes from telemarketers

Alarmed at the rising pesky mobile calls and text messages by telemarketers, the Telecom Regulatory Authority of India (TRAI) on Thursday directed all telecom service providers to reverify registered headers and message templates on distributed ledger technologies (DLT) platform and block all unverified headers and message templates within 30 and 60 days, respectively.

In a new directive, the telecom regulator said that the mobile operators need to ensure that temporary headers are deactivated immediately after the time duration for which such headers were created.

TRAI issued the new directions to providers to stop misuse of headers and message templates and curb unauthorised promotions using telecom resources.
