Cisco Quad is significant for the way it ties together social networking and unified communications. Many of the leading platforms provide the notion of a "contact card--move your mouse over a person's name or profile picture and up pops a mini-profile. This is similar to how consumer social networks will let you see a few pop-up details about a connection to make it easier for you to determine who to follow or establish a connection with. Most enterprise social networks will include a person's phone and mobile numbers in the contact card and also an instant messaging option. Quad also wants to make it easier for you to start a call or a video conference through your Cisco-powered network.
In this image, you can see that the Quad home page also displays a summary of the users waiting voice mails, with phone and video icons to make it easy to return the call.
Early success stories for Quad include the international law firm Minter Ellison.
