In a bid to boost fixed line phone connections in the country, telecom regulator Trai had yesterday removed charges that a landline service provider has to pay to the other service providers for transmitting its customers' phone calls - a move that is likely to lead to lower tariffs.
Trai has also reduced network interconnection usage charges (IUC) on calls made from mobile phones by about 30 per cent to 14 paise per call from 20 paise earlier.
BSNL dominates landline phone connections with 62.71 per cent market share followed by MTNL 13.04 per cent, Bharti Airtel 12.55 per cent, Tata Teleservices 5.98 per cent and Reliance Communications 4.39 per cent.
