Given how unreliable interviews can be (both phone and in person), you'd have to solve it with another mechanism. At my last company, we "screened" ~200-500 candidates per job with a work sample. It was really hard to put together, and worked amazingly well once we had it going. We did a structured interview everyone who passed the work samples and it never felt like a waste of time.
