What is VoIP? VoIP stands for Voice over Internet Protocol (VoIP) and is also alternatively known as Internet Telephony. VoIP allows you to make phone calls over your ISP (Internet Service Provider) connection, instead of your phone company, by sending voice (data) over the internet. How does VoIP work? Current telephone system relies on reliable but inefficient method for connecting calls called ‘Circuit’ Switching. When a call is made between two persons, a ‘circuit’ is established and the connection is maintained for the entire duration of the call with a dedicated wire connection between two persons. A long distance call costs high, because of the copper wire that connects all the way from one point to another.

Yes I agree that IP telephony allows you to make call via internet. but circuit switching is no way in effecient way of communicating the voice data. The time required to establish the connection is no doubt more but once connection is established than it transfers the data effeciently. However the cost of circuit switching is much higher than IP telephony. While using IP telephony our voice packet simply travels like an ordinary data packet accorss the internet and than on the reciever end this packets are received and transformed into voice frequeny.
