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).

I received a call from this number and responded. I was told that I am a defaulter to IRS and if don't pay immediately then will be arrested. I became a victim and lost money. This scam is run by a group of people from Pakistan origin and targeting Pakistani / Indian people living in USA. Stay away and report to Police.
