VOIP is Voice Over Internet Protocol. It is using the internet protocol to communicate. To explain VOIP, it is important to understand how traditional phone calls operate.

Traditional phone calls use circuits to make the connection between phone lines. During the entire duration of the phone call, the circuit remains open whether or not you are speaking. With this method, you will have wasted space.

VOIP does not use circuits, but utilizes packets. Packets are more condensed and do not transmit during the entire phone call. It only transmits as data (voice, video, or etc) is sent, and it is sent via small "packets". This form of transmission is more efficient and the file is considerably smaller than the traditional phone call.

Computer to Computer: This is the simplest method for VOIP. You don't need to invest in too much equipment you just need a microphone to speak, speakers to hear the caller, a sound card on your computer, and an internet connection. Most computer owners already have all of these items. There are several options for software, and some are even free. This type of connection does not have a charge (minute to minute charge).

Computer to Telephone: You can use your computer to call someone on their traditional phone. You would need the same items as the computer to computer method, but software designed to connect calls to a telephone. This type of connection usually incurs a charge per minute (similar to traditional phone calls, but less expensive).

Telephone to Computer: You can use your telephone to call someone on their computer. This method requires the computer owner to have software installed to accept phone calls. This method also has a charge per minute, but is less expensive than calling from your home phone.

Telephone to Telephone: This is the most complicated and costly to install. You must use a gateway to allow this connection. There are several organizations that offer their services. This method also charges for the phone call.

VOIP has the potential to completely revolutionize telecommunication as we know it.
By utilizing the internet, the potential cost savings is phenomenal. The average cost of long distance phone call could be cut in half or completely eliminated. Think about all the phone calls that are made each day throughout military installations in the U.S and overseas. This potential cost savings could stretch the much needed dollar even further in DOD.

Another benefit would be the elimination of telephones. It will not only save space in the office, but it will save your organization valuable dollars, you won't have to buy new phones every few years....you can let your computer do the walking....on the telephone screen.

We could use VOIP and programs such as Microsoft Net Meeting to have virtually free meetings with friends and family from across the world.
