What is a softphone?

in

A softphone is a software program for making telephone calls over the Internet using a PC or laptop rather than using a SIP phone. A softphone is designed to behave like a traditional telephone, sometimes appearing as an image of a phone on your desktop, with a display panel and buttons with which the user interacts. A softphone is usually used with a headset connected to the sound card of the PC, or with a USB phone.
