TRAI has permitted the ISPs to provide Internet telephony which means they can terminate Internet telephony calls on PSTN (public switched telecom network) and vice-versa.
Till now it was possible to call from a computer to another computer over the internet. However it was not possible to call from a computer to a mobile and vice versa. The situation is set to change now.
This seems to be a good news for ISPs and also for mobile handset makers. However this may serious drop in profitability of telecom players in the long run.
