While I haven't used this yet, I did take note of GrandCentral.com.

This is a free website that that offers to unify all of your telephones into a single number. 

By using GrandCentral, you can have your home, cell and other numbers all ring when you get a call to your GrandCentral number.  You can also "listen in" as voicemail is being recorded, or transfer a call from you cell to your home phone or vice versa.  There is also a spam filter:  the system will play a "this number is not in service" message along with the annoying beep to callers from predetermined numbers.

I plan to check it out.  If you use it, don't want to use it, plan to use it ... let us all know what you think of it.


And ... should you find other, interesting sites or services ... post her to let us all know about them!
