| | Airtel wants to charge extra for VOIP usage
VoIP also just like normal phone call but it just happens over Internet,
the call you speak is not transmitted as datas , this not just like chat, where you reply after they reply, its instantaneous so there will be dual channel link between you and your caller, this demands more network usage than regular Internet use, this loadsup the network, so they burn more fuel than regular internet useage, also they use VoIP protocol so when ever you make a skype call, your phone makes a link to network using a VoIP protocol not just TCP IP ,or ipv4 , so network well know that you are making a call,so they filter you and charge you, there is no way if escape here, :( ,
even you watch a live stream in any website where your video or audio is sent back to them,it comes under VoIP, so its a bad thing over carriers to charge us like this,
so better use google talk,where it uses a different VoIP protocol, if the airtel fiters that too,it can't be done.
VoIP is not like getting a data and sending a data
it sends a stream if compressed voice in a TDM network where you get caller voice in another channel .
but sent in data packets. where its bit different to understand.
just a simple answer
using VoIP loads up your network and network works more for you, creates a separate road for you both and make you talk, but where in normal internet useage you drive in public road. :O
