<human>: This happened just an hour ago and I still feel embarassed.

It all started at work. I am sitting in my office that I share with a colleague. I work at a recruitment agency as researcher and therefore need to have regular phone calls with my consultants in order to stay up to date with the jobs we are currently searching for. So after i finished one of those the consultant asked me if I could transfer the call to the other colleague in the room, because she needed to talk zo him, too.

Now here is the catch. I just currently started working this job and in my last position you had to simply press transfer and the internal number. The number my colleague had is 112, which is also the german emergency line. But because this is a closed internal phone network I just fugured it would work as the previous one I knew. 

So I press transfer, dial 112 and wait for his phone to ring. It didn't and I got really nervous. Then someone picks up, says "fire department" and I just instantly end the call out of shock.

Turns out the consultant got,  through that, forwarded to the Fire Department and thought my colleague tried to prank her by answering the phone like that. It apparently took some time for her to figure out my mistake during which she repeatedly asked the man on the line to stop joking, at which point she apologized and got out of the line asap.

Summarize the given text in a few sentences.
<bot>: Due to me being too stupid to use the phone my colleague blocked an emergency line asking the fire depot to stop trolling her.
