In a bid to curb the menace of unsolicited commercial calls, the TRAI on Thursday announced new regulations that mandate registration of businesses/telemarketers for making such calls and subscribers' consent for receiving the same.

Named the Telecom Commercial Communication Customer Preference Regulations, 2018, the new rules provide for "the subscriber with complete control over their consent and the ability to revoke the consent already granted, at their option," a statement from the Telecom Regulatory Authority of India (TRAI) said.
