If your cat is say, casually walking by, and you call it by name, odds are that it will stop, if only momentarily, perhaps look at you, perhaps not, and then continue on it's way. This usually means there is no intention to 'get back' to you and any time soon! If they do, it will be for another reason altogether. Cats are kind-of narcissistic. If they perceive, infer, or conclude (always) the problem you are trying to explain is your problem, then obviously, it is your problem! And you bothering them with your problem is, of course, your problem. How can they make that more clear. Cats are pretty good about bringing you their problems, hence, its a one way street.
However, this aside, they are excellent listeners. They will tirelessly, give an ear. Just don't be too surprised if they simply act as if either; A)they have heard enough, or B)they weren't listening at all. When this happens, they will quickly decide that a nap (probably) is more therapeutic then offering you support. Try not to be offended, that's how they are; Easy come, easy to a nap!
