If you use VOIP or are thinking about it, this might be the product for you…
By plugging the Call-in-One to your ethernet IP network as well as your phone line, then plugging any old phone into the Call-in-One, regular phone calls are routed as normal, while dialing a ‘#’ before your call will place your call via SIP. What this means to you is a seamless integration of SIP–a universal Voice-over-IP protocol–into your regular phone. [Gizmodo]
