Phone me now is giving away accounts that include 100 free minutes a month.

What I like about “phone me now” is the way that it allows you to include a connect to me number with a wide variey of options.  You can add their application to your documents, website, even pdf.  When users click it, it will ask them to enter in their telephone.  It will then ring their number and call yours for free.  This keeps calls to your phone anonymous and lets you integrate your number into a multitude of applications.

Example: Say you offer customer support.  You could include phone me now’s application on your website and any users who had a problem could call you for free.

You can sign up here.  So far it seems as if they are only accepting USA numbers.
