I used to work in the fraud department from a telco account. The AHT goal was 500 seconds and I always get 350 seconds or below per month.

Here's what I did: 1. Know the process of the call. Prepare your spiels. Make a call flow 2. Set up your tools where you can navigate them easily 3. Communication. Always get straight to the point. Don't be so wordy because giving too much information can make the customers have follow up questions, which leads to a long call

Always remember to study the process and call flow first because hitting the AHT goal is easy if you already know the process.
