The process of transferring the voice is exactly the same as it would be on PSTN, instead of being transmitted over a circuit-switched network the data is packetized, and transmitted as IP packets over a packet-switch method, Hence IP telephony and VoIP was ideologically the next step in the progression from PSTN.

An additional advantage of VoIP and IP Telephony is that it is similarly less expensive than customary (PSTN) Phone system.
