I worked for an environment where I put on a microphone and answered questions on a conference line

Hello,

I'm writing an essay about my military experience for my job application.

I worked for an air control job and I want to say:

"I worked for an environment where I put on a microphone and answered questions on a conference line."

I want to deliver what I did in a concise way for readers to understand and grasp what I did easily.

Are there any suggestions as to put this setence, words differently and easily?

Thanks!
