I bought this phone as a backup for my house phones and as a test set when something goes wrong. AT&T will charge you a fortune if they come out and it's your problem. I need a test set that I can take to the demarc (the panel outside your house) and that I can plug in to verify where the problem originates. I haven't had to use the phone yet, but it seems well suited for what I wanted.

This unit is small and light weight, but does the job. Enables you to check the line into your house when you have phone problems.
