New Delhi, Dec 24: Department of Telecom (DoT) has extended the duration of archiving call data and internet usage records of subscribers to two years from one year due to security reasons.
The amendments in the licences were issued on December 21 and extended to other forms of telecom permits on December 22.
“The licensee shall maintain all commercial records/call detail record/exchange detail record/IP detail record with record to the communications exchanged on the network. Such records shall be archived for at least two years for scrutiny by the licensor for security reasons…,” the DoT circular said.
Telecom companies may destroy the data stored thereafter if there is no direction from the DoT thereafter.
