Pros
It does what it says it does
Cons
None works great
Summary
Modem Compatability and WinXP problems

Pros
None, none, and none.
Cons
Does not work and no way to change settings. I use com port 3 for my modem. "No Sales Calls" worked, but for only 30 days and no way to purchase to continue. Will still look. Goggle voice is good for new phone system setups.
Summary
Works very well

Pros
There are none!

Does not work even though I have caller id and my modem supports it. I downloaded new driver and verified capability with hyperterminal as per instructions. But still does not work.
