DoT has suggested a reduction in the revenue share licence fee across services. These services include intra-circle calls, domestic long distance calls and internet protocol-virtual private network (IP-VPN). The move has been prompted by a DoT proposal to reduce the licence fee for NLD operators to 6 per cent from the present 15 per cent. Telephone operators pay an 8 per cent licence fee for all calls within a circle. Officials say DoT's finance wing had pointed out that this might result in a diversion of intra-circle calls and that they could be routed throughNLDOs. The finance wing has also pointed out that unified access operators pay a differential licence fee, ranging from 5 per cent to 10 per cent, depending on the circle they operate in.
