Query: Didn't work!

We had at the time two land lines, one had long distance the other didn't . The one without was dedicated to free number out faxs and computer so nothing would block incoming calls that might be emergencies. We wanted to decrease our phone bill so decided to cancel one line and on the advice of a friend at Radio Shack that this device would be just the ticket. That Radio Shack used to sell them but no longer. We attached it just as the instructions called for but it wouldn't work! So we trashed it and got the internet faxing ability from FAX.COM. It works great! Sorry about the product and that you did not want to hear the things I said about it but it was a NO GO!!
