I haven't actually done this in production, but at various times when testing, I have noticed that if you have multiple dialer strings on the one dialer interface, the first string will be dialled, and then if that fails, the second string will be dialled, and so on. I suspect that what you want to do would work, although I doubt it would load balance between the two numbers - I think it would normally dial the first number, and only dial the second number if the first one failed (or is engaged?)
