The acronym VoIP stands for Voice over Internet Protocol. VoIP is also commonly referred to as Broadband Telephony, Broadband Phone, Voice over Broadband, IP Telephony, and Internet Telephony. VoIP refers to routing voice conversations through any IP-based network such as the Internet. Voice signals are carried over IP-based networks with the use VoIP Protocols or Voice over IP Protocols.

The creation of VoIP resulted from the 1973 experiments with the Network Voice Protocol which were performed for ARPANET providers. Data and Voice are carried through one network which is beneficial to people with an underutilized network. Using VoIP will help you save money because providers will usually allow to make VoIP phone calls for free. But you will be charged for making a phone call from VoIP to PSTN.

Access numbers and Direct Inward Dialing (DID) are the services associated with PSTN to VoIP calls. If access numbers are used, you must enter the extension number of the VoIP user that you are trying to call. However, using DID will allow a caller to directly connect to a VoIP user. For VoIP users and local calls, there is no charge for using access numbers but there is a monthly fee for using DID.

People who use VoIP will look at long distance phone calls in a different way. For the VoIP technique, audio analog signals are converted into digital data signals that are transmitted through the Internet. This essentially means that using VoIP will allow you to make free phone calls. This will allow people to save money by bypassing the charges from phone companies.

The innovations of VoIP technology will give people the ability to rewire the phone systems all around the world. Although a phone call made with VoIP is one way, VoIP offers many services that are frequently used today.

1. The most common service involves the use of the ATA (Analog Telephone Adapter) device. This device gives people the ability to use VoiP technology over their phone connection. It is used to convert analog signals into digital signals. Then these digital signals are sent over the Internet.

2. People who want to take advantage of VoIP must use IP phones. An IP phone looks like a normal phone. It has buttons, a cradle, and a handset. However, there is a difference in the physical connector each phone uses. A normal phone uses a phone connector (RJ-11) while an IP phone uses an Ethernet connector (RJ-45). Your IP phone will be connected to your router with all of the hardware and software that is required to handle IP calls. Manufacturers will soon be making Wi-Fi IP phones available for purchase. These phones will allow you to make VoIP calls from any Wi-Fi hotspot.

3. The easiest way to use VoIP is with a computer-to-computer connection. The user will be able to make long distance phone calls for free. This method can be implemented with free or very affordable software that is offered by several companies. This method will only require the use of a fast Internet connection through a cable connection or DSL modem, sound card, microphone, and speakers. However, the user will have to pay a monthly fee to the ISP.

Since there is plenty of free VoIP software on the Internet, a user will not have a problem trying VoIP. You can download the software and set it up in under five minutes. You can test the VoIP connection by inviting a friend to download and setup the same software. Then you and your friend can attempt to talk to each other through your VoIP connection.

There are many phone companies that are streamlining their networks by utilizing VoIP. They can reduce the bandwidth that they are using for long hauls by routing their phone calls with IP getaway and circuit switch. After the phone calls are received by the getaway, the other side will route, reassemble, and decompress the phone calls in a local circuit switch.

The circuit-switched networks that we have today are being replaced by packet-switching networks. Packet-switching networks will retrieve and send data when it is necessary. They will not route data through a dedicated line. Instead, they allow data packets to travel through chaotic networks that have numerous possible paths. The packet-switching technology will open brief connections in order to allow packets to travel from system to system. This is a very efficient method because it allows packets to travel through the least congested and most affordable lines and gives both communicating computers the opportunity to accept information.

Economic and infrastructure requirements can be met by IP technology. VoIP systems are becoming very popular among businesses. As VoIP becomes more popular, it will eventually end up in many homes. VoIP has been a breakthrough by making traditional phone systems more efficient.
