B calls at t=AB. A hears phone at t=AB+BA (so A knows AB+BA)

What does this mean?  Does B call back again at t=AB (that doesn't make
sense) or are you assuming that B can instantaneously "hear" the ring
from A's end at the first call and so calls A at t=AB+BA ringing at
A's end at AB+2BA?  I think this is where this method comes apart.
