It's a newer build. Probably 2008, and it appears it was done during the build. I was thinking that maybe th normal guy was sick so a new guy did it and didn't punch down the jack properly. There are also phone jacks that apear to work but when she had her alarm installed about 2 months ago the installer told he the wire he was working with was wrong and he had to change some things around to get it working. No idea what he fixed.
