| iVoice Telecom Softphone is a software program for making telephone calls over the Internet using a general purpose computer, rather than using dedicated hardware. Often a Softphone is designed to behave like a traditional telephone, it appearing as an image of a phone, with a display panel and buttons with which the user can interact. A Softphone is usually used with a headset connected to the sound card of the PC, or with a USB phone.
