Details:

A typical user calling from a land line or mobile phone will be able to reduce and even eliminate international and long distance telephone charges by first calling their SPA-3000 via a local phone number or by using a telephone connected directly to the unit. The advanced authentication and call routing intel-ligence programmed into the SPA-3000 will connect the caller via the Internet to the far end destination with security and ease. Using the SPA-3000 at the far end, calls can be answered immediately or further processed as a local call to any legacy land line or mobile phone allowed by the SPA-3000 dial plan.
