What is Internet Telephony?

Internet Telephony (IP-telephony) – a technology that uses the Internet to transmit voice signals.

How does Internet telephony?

In the conversation, our voice signals (words that we say) are converted into compressed data packets. When these data packets are sent via the Internet the other side. When the data packets reach the recipient, they are decoded into voice signals of the original.

What is the difference between Internet telephony from regular telephony?

In a conventional telephone call connection between the two interlocutors is established through a telephone exchange solely for conversation. Voice signals are transmitted on certain telephone lines, via a dedicated connection. When you request the same on the Internet, compressed data packets are received on the Internet with a destination address. Each data packet goes its own way to their destination by different routes. For the recipient, the data packets are decoded and rearranged in the original voice signals.

Regular telephone calls require an extensive network of telephone stations connected fixed telephone lines, supply of fiber optic cables and satellites. The high cost of telephone companies lead us to expensive long-distance calls. A dedicated connection telephone exchange also has a lot of excess capacity or idle time during the speech session. Internet Telephony is partly based on the existing network of fixed telephone lines.
