Why does Internet Telephony cost less?
• Regular telephone calls require an extensive network of telephone exchanges, connected by fixed telephone lines, undersea fiber optic cables and telecommunication sat ellites. The high infrastructure investment by the te lephone companies results in expensive long distance calls for us. A dedicated telephone exchange connec tion also has a lot of excess capacity or idle time d uring a voice call. • Internet telephony rides partially on the exist ing network of fixed telephone lines. It also uses the ltest technology to compress our voice signals, and to fully utilize the capacity of the telephone lines. Data packets from different calls, and even different types of data, can travel along the same line at the same time.
