Digeo's VoIP Moxi Telephone app for the Moxi Media Center
We've never once wanted to make a phone call using our TiVo or even our Media Center PC (shocking, we know), but Digeo's adding some intersting VoIP functionality to their line of
Moxi Media Centers digital video recorder set-top boxes (which are currently available to some Adelphia, Charter Communications, and Comcast cable subscribers). Doesn't look like you can actually make outgoing calls, but you can use their new Moxi Telephone application to listen to voicemails, answer incoming calls, see caller ID, and redirect a call to another number or send it straight to voicemail.
