Trai directs telcos to check spam calls, texts using AI/ ML
The telecom regulator has asked all telcos to deploy detection systems using artificial intelligence and machine learning (AI/ML) technologies to identify and rein in spam calls and text messages from unregistered telemarketers (UTMs).

OOPs sorry, This is an ICICI Bank service number, which promotes Debit card offers / updates about their service etc.
who ever is calling is from IT call centers. Beware of them.
