Bharat Sanchar Nigam Limited (BSNL) has said that it will take 10 months to implement the Telecom Regulatory Authority of India?s (TRAI) suggestion of establishing an identifiable number series for tele-marketing firms.

Prior to this, TRAI, in its regulation to put a check on unsolicited calls and text messages, had directed operators to allocate an easily identifiable number series for tele-marketing companies.

On a request from TRAI, the Department of Telecommunications (DoT) has issued a number series starting with ‘140’ to tele-marketing companies for mobile phone numbers but not for landline connections.

To implement this number series, it is essential for BSNL and Mahanagar Telephone Nigam Limited (MTNL) to install modern equipment in exchanges.
