A SoftPhone is a computer software application for making telephone calls over the Internet using a regular PC or a PDA, rather than using a regular phone device. Beside being a lower cost alternative to traditional phone systems, It provides numerous advantages compared to regular land-line phones and cellular phones. Not just telephone companies, businesses at all sizes could easily deploy and immediately benefit from the rich functionality and the low cost of SIP based SoftPhone applications very quickly.
