SiPphone Call-in-One is the first SIP product that looks useful enough to buy. Rather than replacing your current phone, or adding a second SIP handset, the Call-in-One acts as a sort of PSTN/POTS (regular phone service) and SIP router. 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. At this point I would normally make some joke about how much fun it will be to call the six other people that use SIP, but full-on VoIP is the way to go in the future, so soon there will be at least seven people you can call via SIP.
