I've worked for the same life/health insurance company for over 26 years(not Aetna, though). I know our Customer Service Reps are most definitely in a call center environment. I did it for a couple of years part-time and did enjoy it, for the most part. Our company does not believe in work-at-home, but not sure why. I know I'd get more work done in the peace and quiet of my home. Just be sure you know the hours expected of you as they like to gloss over that fact before you're employed.
