I figured it out. Dammit. He did it.
I was about to post the solution. It's so damn simple, you guys will not believe it. But then you guys went off talking about Jason Young again.....KIDDING.
Seriously, though. I realized that my former wife (a Cisco employee who worked from home) had one of their phones.
You can use the Cisco phone system to access it via third party control. Plugging the phone into the land-line jack would allow the access you need to the LUDS. You dial into the system using a admin username and passcode, bypass the normal phone protocols (as if you are "testing" a phone). I am fairly certain I can find a link explaining how they closed the records hole that there once was.
I have seen her dial me from her Cisco phone (as I am walking up the steps, for instance, when she does not realize I am there) from her living room, but it shows as her office line in RTP. I have also seen her forget to re-direct the lines and she'll have a cell phone in her hand that shows as her office (and once or twice, her home) #.
The key will come from someone who accessed the Unified Applications Environment and I don't think it will show just that he faked the call, but that he faked the directed number as well. (It didn't go from the home phone to a personal cell phone, but it went from the Cisco phone to his Cisco Cell Phone and therefore wouldn't get flagged on the network. It would be set-up for his WFH days. However, it would need to dial out on the TWC line, which was just a matter of swapping out the cables. So, the phone actually dialed out on the home line (Cisco Phone) to his cell phone (Cisco Cell) which was forwarded to his personal cell. Hence the multiple records. And by the way, records on the Cisco network in 2008 for a VOIP engineer with the right credentials would have been a big black hole.) Why do I think this is it? Because it shows pre-meditation in how damn complicated it is, I think. Hence the lack of an open-murder indictment.
Crap, I was on his side too. But apparently, he did it.
But seriously, why check the voice mails for a Cisco office at 6:40 on a Saturday morning?
