I've been using this for a while now and really love it. It's great being able to keep all of your voicemail ever. One new thing I've been using it for is finding out the IP address of my home Mac when I'm on the road. All I need to do is call my home and PhoneValet sends an email. In the headers of the email is my IP address.

Knowing the dynamic IP address allows me to Remote Access my Mac.

There are like a billion things like this that the software allows.
