  Ah, well, then I don't think we're really talking about "land-lines" then.

  Ten years ago, during college, I worked for "The Phone Company" as a
switchman.  Way back then "land-line" meant metal.  Specifically, no
multiplexing (no microwave, no fiber, no satellite).

  But in any case, the receiver doesn't determine the routing.  If an
ordinary consumer makes a call it is routed via the most viable route.

PS:  There is a difference between copper wire, and microwave or fiber.
     Microwave and fiber are multiplexed and thus have some scheduling
     delays, albeit small.
