Well, every single time I have talked to someone over the phone about a job, we have ALWAYS discussed a salary range. Either they ask me what my salary range is or I ask them.
However, I only ask if it sounds like a job I may not be that interested in. 95% of the time the employer is the one to ask me first, at which point we discuss whether my range is somewhat comparable to theirs. Most of the time they don't want to waste their time on me, just like I don't want to waste my time on them.
So I guess you run the risk of either being told that that information cannot be given out, or they may cut off contact with you like your previous experience. I would only do it if you were not sure you wanted the job,therefore not much to lose.
