No, but there is a Gizmo Project VOIP phone, which is a standard SIP phone so it can call (for free) most other open SIP phones worldwide - and it can can have a free incoming number from ipkall, makes it cheaper than Skype.

Not much use I know if you're in a company that currently uses only the non-standard Skype phones, but if what you really want is any VOIP phone, it's available.
