VoIP stands for voice over IP. It is the ability to send/receive voice communications using the internet. There are a number of methods for doing so and different types of devices that are available. A soft phone is a software phone that runs on your computer. In order to make calls, you will have to have your computer turned on, the soft phone software running, and a voip service provider so you can actually make calls. Many companies who run their own asterisk voip system will set up their employees with soft phones so they can be reached anywhere.
