Voice over Internet Protocol (VoIP) is a technology that works by converting sound into digital voice communication. Instead of sending and receiving calls over “traditional” copper landline telephone infrastructure, that information is instead sent over an active Internet connection. The way that voice data travels over the Internet in this situation is virtually indistinguishable from any other type of data, with e-mail being one of the more prominent examples. With VoIP, you have a wider range of options regarding who you can actually call at any one time. You can make computer-to-computer calls, you can call a cell phone, or a landline like you could in a traditional setup.
