TRAI also pointed out that while some native smartphone tools and third-party apps like Truecaller and Bharat Caller ID & Anti-Spam already offer spam identification and calling party name identification facilities, these services rely on crowd-sourced data which may not be entirely trustworthy.
In its recommendations issued Friday on calling name presentation (CNAP) service, the Telecommunications Regulatory Authority of India (Trai) said, “the government should issue appropriate instructions for making CNAP feature in all devices sold in India, after a suitable cut off date, say after six months from the date of notification.”
