Mumbai, Aug 27: The Bharat Sanchar Nigam Ltd (BSNL) will switch over to the Call-Detail-Record (CDR) billing system for its 3.5 crore landline subscribers in the next couple of months.
"Our landline billing system as of now works on the conventional technology, and we are unable to give a customised offer to subscribers. But very soon all that will be a thing of the past," BSNL Deputy Director General, (Enterprise Business), Sunil Kumar said.
