Hi Friends most of the users have doubt's whether VoIP in India is legal or not.
The answer is Yes VoIP is Legal in India, with only some of the VoIP providers.
Using Vonage, Packet 8 and etc., are illegal according to the Department Of Telecoms. I have a friend who is using VoIP through :: Welcome to TrigunaSolutions :: this is a Legal Provider for all International calls made from India. Go through the website, they do have attractive prices for Domestic as well as for Corporate use.Its good to take a service locally as the customer support and service team would help the users to troubleshoot many technical issues.
