It's a virtual phone, a piece of software installed on your PC that allows you to make calls over the internet, and a lot more besides. So what's making calls without a handset actually like? Find out with our hands-on (or should that be 'hands free'?) demo...
Here's a reminder of some of the key phone features:
Six way voice and four way video call conferences. Fantastic, if you can get a word in edgeways
Instant messaging
Call display and message waiting indicator. See who's next in a long queue of people just dying to talk to you.
A speakerphone for when it's no big secret and a mute button for when it is.
Redial, hold and Do not disturb
Call ignore and Call history
Call forward, transfer and Call record
Adress book management - import and export your contacts between your phone and other applications Microsoft Excel, Microsoft Outlook, Microsoft Exchange or vCard.
