Communicating online is a big part of the Internet. As mentioned earlier, traditional International phone calls lead to outrageous phone bills. The Internet offers a complete solution to this problem - internet phone calls.

How this works is that the Internet needs some kind of device to convert voice to data that is transferable over the Internet. Of course, at the other end, a similar device is needed to convert the data to voice again. As high speed Internet connection is very cheap these days, internet phone calls are usually free. Even if there is a fee chargeable, that is usually much less expensive compared to regular fees.

The special device here is commonly known as the IP phone. IP stands for Internet Protocol, and this is the protocol that is used for transferring data over the Internet. This phone is plugged to the Internet directly. Sometimes special software is needed to get the data from the IP phone, convert it to data that is transferable over the IP protocol, and then send to the Internet. The Internet does its work, and the data is transferred to the other end - another person with the IP phone.

Similarly, the computer at the other end converts this data back into voice data, and the user can hear what you are saying. As the whole process is about converting data to voice and voice to data, this technology is commonly known as Voice Over Internet Protocol (VOIP). That means transferring of voice over using the IP protocol.
