Motorola unveiled the C51 cordless phone, providing access to landline, VoIP calling, cellular service, live streaming video and lots of other cool features at the 2006 CES. Utilizing 5.8GHz technology, the C51 starts with a chosen base station to make calls using landline or digital phone service.

It also supports home intercom, shared family phone books, Push-to-Talk over IM and high-speed internet access. Basically the C51 is an all-in-one package from Motorola. Using a VoIP phone adapter, you can access any Internet phone service from any handset.

The C51 also features hands-free speakerphone, caller ID and message forwarding. Using an optional USB cable, you can use the PTT-over-IM feature which sends your voice over the Internet through a supported Instant Messaging program (no mention of which one it is, though).

The Motorola C51 is a 2006 International CES Innovations in Engineering and Design honoree. More info is available from Motorola's website.
