Michael Robertson's SIPphones now unwired

Consumer 'Net telephony company SIPphone.com (founded by Michael Robertson of MP3.com, Lindows, etc) announced today the release of an adapter that allows you to plug in any cordless phone and go. Previously, if you wanted to use their service to make supercheap (basically free) international calls, both parties on the phone conversation had to have a SIPphone. Now, you can use a "regular" cordless, with adapter. A single SIPadapter can be purchased for $79.99 and a 2-pack is available for $149.99.

Each SIPadapter comes immediately ready to use with no monthly fees or
activation fees. There is also no per minute fees, so callers can avoid large
long distance charges which means a SIPadapter can pay for itself in a very
short time.

There's background in this story I did for Wired News a few weeks back.
