State-owned Indian telco Bharat Sanchar Nigam Ltd (BSNL) is reportedly set to invest between INR8 billion and INR10 billion (USD160 million and USD200 million) on reviving its fixed line voice business, according to the Business Standard. The telco is understood to be in the process of implementing call data record (CDR) system that will enable automated billing, as well as the identification of network faults and the monitoring of the entire wireline business. ‘After the mobile revolution, growth in landline phones had stagnated. We are now bringing our landline business back in focus, to improve our broadband penetration. We are in an advanced stage of implementation of CDR for landline business. There will be a self-care portal through which customers can see and print bills and also make payments online,’ a senior BSNL official was cited as saying. The operator is also reportedly planning to construct a call centre to address customer queries; it currently only offers an interactive voice response system via which its landline users can make enquiries.
