As for me, I'm usually ready for work 20 minutes before my shift. I'll read all my work-related emails, then when it's time to start my shift, I put the head-set on and start receiving calls. It's not all talking and we get regular breaks or so. Sometimes, you have to handle calls one after another but normally, while you wait for calls to come through, you can talk to your work buddies too. The most enjoyable part is to relate to people and help them out of their problems.
