The part is cut in. When Nute says altright listen in the background....you catch a phone suddenly ringing in mid ring, Rick was about to say something and Nute is trying tell him he wants information. In other words right at 23-24 seconds you can hear the difference in the recording and how it steps on the existing background.

Must admit...it does kind of sound like 2 tracks joined together.

Then at 1:19 you hear Jen saying " guys there is a shooting at Sandy Hook school that's why 911 is ringing off the hook" I can only assume she is still calling police.

I'm assuming she's yelling into the police station...which they are attached to.

Now at 1:42 while Nute is asking Rick what his position is at the school you here Jen pick up a ringing phone and you can hear her say " at the school? Dickenson? Okay what's the (can't quite make out the word but it sound like story)then there is some cross talk while Rick and suddenly another dispatcher jumps in and asks what the address is for the school and then Jen blurts " there's a rumor it's fake" Or she says " are you in a room where it's safe?"

I can't make out what is said when the phone is answered...but I was also confused by the addition of another voice on the call with Nute and Thorne. I also couldn't understand why there is so much overtalk. They must have mute buttons but there are several times where a dispatcher is speaking to someone not on the phone and it confuses the callers.

There is a lot of editing on this call that is obvious. If she was on the phone with someone in the school or had info about the school why would Nute tell her to get off the phone?

Why can't we here Jens call?

There are other calls we're not hearing as well. Janet Robinson obviously called in and another woman Nute spoke with...but if these were not directly related to the events going on in the school it's unlikely we'll ever hear them.

We obviously haven't been given near all the calls. Hopefully the entire report and all accompanying 911 calls will be released at some point.
