New Delhi: In a move than can end the free regime for domestic calls made through Internet messenger services such as WhatsApp, Viber and Skype, a high-level panel has suggested that they be benchmarked against regular telecom service providers for tariff and regulation.

Yet, it has said that communication services offered by them dealing with messaging should not be interfered with through regulatory instruments. "For these application services, there is no case for prescribing regulatory oversight similar to conventional communication services," it said.
