One of the easiest ways to use a traditional telephone with Skype is to use a USB based adaptor such as the CU Free Echo Free USB Phone Adaptor. This matchbook sized USB key has two standard telephone ports on one end, allowing the user to connect a traditional telephone as well as connect to an incoming land line circuit. Using the adaptor and included software, calls coming into the home on the old land line are routed to the telephone handsets as normal, but outgoing long distance calls are automatically routed through the computer and the Skype service. The Echo Free adaptor also includes other useful functions such as 3 way conference calling and call forwarding to a cell phone or any desired phone number.
