The phone call lasted 26 minutes. During the call, noises including gunshots, explosions, screaming, and yelling can be heard. The initial backround noises heard come from the hallway just outside of the library. Four minutes and ten seconds into the call, Harris and Klebold entered the Library and begin shooting. They left the Library eleven minutes and forty-five minutes into the call. The remaining gunshots and explosions heard on the tape occur in the Cafeteria, Science classroom area or the hallways of the school.
You can find the full audio here — as much as has been released to the public. The sound cuts out at 5:22 where the audio was redacted before it hit the public. It picks up again at 8:11. WARNING! The end includes the heart-wrenching screams of Valeen Schnurr which are incredibly disturbing to hear.
NOTE: The timestamps for this dispatch transcript are a little over 3 minutes faster than what is shown on the Columbine High security camera footage. For years, researchers (and this site) have used the security camera timestamps to specify event times. So, if you spot a discrepancy in the time the FBI documents state something happened and what the CCTV footage shows or what's listed in other references, try adding 3-4 minutes to those timestamps.
This portion of the transcript was pieced together from reports that leaked after the official declassified information.

11:27:51 NIELSON: Yes. I am a teacher at Columbine High School. There is a student here with a gun. He has shot out a window. I believe one student—uh...um...um... I've been— I don't know if it's... I don't know what's in my shoulder, if it was just some glass that went through it or what.
NAPOLI: Has anyone been injured, ma'am?
NIELSON: Yes! Yes! And the school is in a panic and I'm in the library. I've got— Students down! UNDER the tables, kids!! Heads under the tables!!
NIELSON: Um. Kids are screaming. The teachers, um, are, y'know, trying to take control of things. We need police here. We need—
NAPOLI: Okay. We're getting them there.

NIELSON: I said, 'What's going on out there?' and this kid that was following me from Video Production said it was probably a joke, and I said 'Well, I don't think that's a good idea.' and I went walking outside to see what was going on. He pointed the gun straight at us and shot and—my God! The window went out and the kid standing there with me, I think he got hit.
