VoIP Phone System
A Voice over Internet Protocol, or VoIP, transmission is initiated by converting voice into digital format. This can be done by Analog Telephone Adaptor (ATA) or by the computer itself using software. In the Public Switch Transmission Network (PSTN), the dialing of the number initiates the call by connecting the call to the public switch and routing the call to the correct party's telephone number through the telephone network.
A VoIP network also has similar functions like that of PSTN, in addition to the IP provider and Internet Service Provider (ISP). The major components of a VoIP network are user devices (one or both ends), a call processing server, VoIP gateways, gatekeepers and an IP network. The user device consists of VoIP phones, traditional phones with accessories and computer-based devices.
VoIP phones may be hard or soft phones.
A VoIP hard phone is like a traditional phone, but instead of a phone jack, it has an Ethernet port through which it communicates directly with a VoIP server or another VoIP phone. It doesn't need a personal computer, only an internet connection. These hard phones may also come cordless.
A dialup hard phone is one with a built-in modem instead of an Ethernet port. A wifi hard phone is built with a wifi transceiver to connect to a wifi base station to be connected to a remote VoIP server. This can be used to transfer calls to a GSM network.
A soft phone is run by software in the computer.
This requires appropriate hardware such as a microphone, a speaker or a USB port. Once dialed, the phone number is processed by the call processor, which is actually hardware running a database mapping program called soft switch; the software manages all connections. This is also called IP PBX (private branch exchange), similar to the PBX of the PSTN lines.
There are gateways and gatekeepers that control the call admission and bandwidth management. They also control the creation of IP packets that contain the voice data and other information about the call.
Finally, there is the IP network, which consists of distributed routers ensuring connectivity. This IP logical switch is referred to as the soft-switch architecture.
These four components form the phone system for VoIP, in addition to the software and various protocols through which the call is smoothly communicated. .

(ContentDesk) May 15, 2006 -- The internet phone has put the traditional landline phones on the endangered species list. Within a decade, most Americans will be using an internet phone. The average savings to the American family by switching to VoIP is nearly $1,000 a year. Prices can vary anywhere from leader Vonage and their $25 a month, or SunRocket and their $199 a year plans.With such a demand for VoIP products, and little information regarding their services, the owner of a VoIP review site decided to create a simple comparison chart for all to see. I thought it was really inconvenient that there was no simple way to compare VoIP , says founder Jonathan Baldwin.
"I decided to put the facts for everyone to see." The chart strips away all the deceptive marketing, and lets the consumer see straight to the naked facts. Price, activation fees, contract terms, and customer service glaring straight for all to see. This has been such a direct hit measure, that even some major VoIP...
