Help staying busy at work

I started a new job a month ago. It is a call center for a bank so I answer phones. For the most part I like my new job but I am having issues because when I'm not on the phone I have nothing to do. I have asked my supervisor is she needs me to do anything and her response is always the same, not right now, we have it covered. I have a lot of down time. Everyone else has other things to work on and I sit there with nothing to do from 8-5pm. Yes I answer phones but when I'm not answering phones I have nothing to do. Does anyone have any suggestions?

I generally don't believe in hassling management too much but in this case it seems necessary. What are the other assignments people are working on? Can you ask for something like others are doing (be specific)? Present it like "I am good at doing X type work and would like to spend my time when I don't have calls working on that so I can be more productive. I am willing and eager to learn".

Boredom is a real killer. I feel your pain. (((maymie)))

Little Lulu, I hate being bored. Yes, I have done as you suggested and still always the same answer, not right now, we have it covered. So this tactic didn't work for me. Thanks for the suggestion though.
