Why VoIP?
This is a very interesting question to be answered before we start with further discussions being the fundamental question of this whole web site. Human mode of communication is the best compared to all the living creatures in the world. First we found new languages to communicate, and then we started thriving for communication over distances. The invention of telephony (Plain old telephone system, POTS) was such a break through for communicating over� geographical boundaries. For more than 100 years it was the unshakeable technology. But as in every other field of technology, better ones always make the old one extinct.
VoIP is one such technology, which has born to challenge POTS in terms of technology as well as business. Business ???� You might ask me why business. Yes, even though POTS solves the problem of long distance communication, there is a cost associated with it. You cannot talk to your loved ones living across the globe with out counting the pennies. With VoIP it is free. You might now ask, “VoIP is free”; no I still pay bills to my VoIP provider like vonage, dialpad etc. etc., yes you are right and wrong. You are right because you end up paying only when you make a call to another POTS line from your VoIP line. In this case your call is carried over Internet as close as possible to the destination and then it is converted to POTS. That’s the reason why your phone bills are so less when it comes from VoIP provider. You are wrong because it is absolutely free to call from a VoIP line to another VoIP termination. The only cost associated is your internet bandwidth. For example look at Skype, Gizmo etc.,
In a perfect world where every corner is connected with internet then the cost for long distance communication is near zero. But it will take a lot more time to reach this situation as evolution takes time. Till then there is business to convert VoIP calls to POTS calls by carrying them over IP to as close to destination. more>>>
