VOIP is any voice sent over IP. It can be the internet or the PSTN. I assume India doesn't forbid telcos using IP internally, because they surely do that because TDM switches are obsolete technology, but they Shall Not Connect to a public IP network.
so when india is talking about banning VOIP they can not mean any voice sent over IP, which makes that distinction matter.
