Save time with VoIP.
These tips apply primarily to Windows 7

You can save significant time—and possibly money, too—by using a
VoIP system that allows you to click phone numbers in Web pages
and in e-mail messages and dial them directly via your PC.
Skype (skype.com) offers such an option, which works broadly in
e-mail and on most Websites, and Google recently integrated its
own VoIP offering, Google Voice, into Gmail (gmail.com).
In addition, Google Voice saves call histories as they take place,
integrating them into the Gmail contact management system.
