Do 911 operators go to the trouble of digging up old tapes and listening to them? Or replay them upon completion of a call looking for distant noises and/or conversations?

I asked this question earlier. It is a serious question. I envision a 911 operator clocking in to work and getting on the switchboard/phones, taking calls, making dispatching calls for applicable assistance, ensuring tapes are rolling, and whatever else.

I do not envision at any point in his/her shift replaying old tapes.

It is possible.

In her response, Wright said the call came in on a cell phone, there was a bad connection, and it was hard to understand. The operator also says equipment problems created a delay.

But Wright claims there was a reason for the delay in the police response. In her response to the complaint against her, she said the call came in from a cell phone and she had to get the address first. As soon as she got the address, she said, the phone went dead. She also said the call was breaking up and she couldn't understand what White said, so she hit a feature that allows for a replay of the call.

In the report, Wright says, "The recording didn't come up. As a result, I had to search for the call."
