What is Internet Telephony?
It allows you to use internet to make and receives calls as you would with your historical phone provider. It uses the Internet and data networks to send and receive calls and faxes. Because it uses your existing high-speed Internet connection, it offers great savings on long distance and international calls.
Simply put, Internet telephony lets you make real-time voice, fax and even video calls over the Internet. Many small businesses are experimenting with Internet telephony, mainly because it can significantly reduce telecommunications costs. You might also hear it called voice over IP (VoIP) google_ad_client = ‘pub-2905054723170537’; // substitute your client_id (pub-number) google_ad_channel = ‘3393335763’; google_ad_output = ‘js’; google_max_num_ads = ‘3’; google_ad_type = ‘text’; google_feedback = ‘on’; google_targeting = “content”; or voice over the Internet (VoI). A somewhat synonymous term, IP telephony most commonly refers to voice calls routed over a private intranet or wide area network (WAN), as opposed to the public Internet. Making Calls over the Internet There are some major differences between making a regular phone call and an Internet call. First, to make a phone call over the Internet, you need a multimedia computer with an Internet connection, a sound card, speakers and
Internet telephony refers to the science or technology of integrating telephone services into computer networks. In essence, Internet telephony converts analog voice signals into digital signals, transmits them, then converts them back again. Voice over IP (VoIP) is a common Internet telephony service. With traditional telephone service, sometimes referred to as POTS (Plain Old Telephone Service), voice signals use telephone lines — copper wires — and circuit switches to communicate. Internet telephony eliminates the telco company all together by using computer networks to send voice signals. All information is transferred across the Internet in “data packets.” For example, if you send your friend an email, the email is broken up into a series of data packets that each take their own route to the destination mail server. Once there, the packets reassemble themselves into the full email message. Internet telephony also transmits using data packets. Analog voice signals are digitized,
Definition: Internet telephony (IPT) is transport of telephone calls over the Internet, no matter whether traditional telephony devices, multimedia PCs or dedicated terminals take part in the calls and no matter whether the calls are entirely or only partially transmitted over the Internet. What is Internet Telephony Good For? The most significant benefit of IPT and driver of its evolution is money-saving and easy implementation of innovative services: • In the future, Internet Telephony Service Providers (ITSP) may use a single infrastructure for providing both, Internet access and Internet telephony. Only data-oriented switches could be deployed for switching data as well as packetized voice. Multiplexing data and voice could also result in better bandwidth utilization than in today’s over-engineered voice-or-nothing links. Not only the providers, but also their clients will profit of lower costs eventually. • Now, customers may take advantage of flat Internet rating vs. hierarchical
