That sucks.
There had to be a better way to back something like that up than just leaving it on a proprietary voicemail system.

Some states both parties have to have knowledge that the phone is tapped. Some states only the person tapping their phone needs to know.
I had a friend that tapped his phone cause he was going through a divorce and thought the wife was also having an affair...She called the phone company to find out if her phone was tapped and they checked and said NO....but it was..
