One thing's for sure: It has nothing to do with the 824. This line hunting is a service provider issue, period. Don't let them tell you anything otherwise. Key systems, regardless of brand cannot provide line hunting on POTS lines. This is always a central office feature.

Why you're receiving ringback tone when calling line one while it is busy is baffling. My guess is that the customer has somehow activated call forward-busy on that line, which overrides the normal preset line hunting.
