This is D-Life
Since D-Link's VoiceCenter is an important Microsoft Response Point partner, I had to visit their CES booth and see their new D-Life service. A beta version has been available in Taiwan for over a year, so the news at CES is that they're now ready to sell it in the U.S.
The basic idea is that whenever you buy a D-Life-compatible piece of equipment, you register it on the d-life.com portal web site. As soon as you connect the device to the internet, it knows to "phone home", automatically provisioning itself and making its services available to you without any further setup.
One of the first devices they're announcing is this VOIP/PSTN hybrid phone:

It acts like a normal DECT cordless phone when connected to a PSTN line, but when provisioned by D-Life, it's a full-blown VOIP phone.
They also announced a few other D-Life-compatible devices, including a security camera that uses Powerline to broadcast MPEG video from wherever you like. By connecting through the D-Life portal you can view the video stream anywhere on the internet.
The VOIP services are powered by a Taiwanese startup called Teltel.
