I generally tell a recruiter on the first phone call to tell me the salary range. If they refuse, I tell them I'm not interested. If they name a range that's low, I tell them what I'm looking for, and see if they're able to budge. If not, I tell them I'm not interested. Sometimes the range is higher than I'd initially expected and end up pleasantly surprised.

Either way, I don't talk numbers first and I still don't waste time with places that can't offer the sort of salary I'm after. I'm not going to even bother with a phone interview if I don't have a firm number in hand.
