Crj-700 captain reports being cleared to descend now to FL240 then descend via the korry 3 arrival. ...

Narrative:

We received a clearance to descend to FL240 and then descend via the korry 3 arrival. We were currently at FL270; I set 24;000 in the altitude selector; we both verified the altitude; and then I asked the first officer if he wanted me to select a different altitude for the korry 3. He told me to set 10;000. I set 10;000; we again verified the altitude; and then failed to immediately descend to 24;000. The first officer was discussing something with the jumpseater. I was distracted by constantly listening for our new call sign; and didn't notice that he didn't descend immediately. It wasn't but a minute or two; and ATC queried us on our clearance. We verified it and the first officer started descending. The added concentration of listening for [for our new call sign] is a distraction in itself. Obviously paying more attention would avoid this situation from recurring.
