When can the C make an over and back call?

[JRutledge]

If the ball started in your primary and all the action with the ball happen in your primary, the C better make the call when it is obvious. It would be very hard pressed for a T to make a call they did not see or did not know why something happen. The T has this as their primary, but that does not mean that the C never can make this call.

Another situation that would be common for the C to make a call is when the ball is near half court on a press or trap, if the ball handler steps on the line or near the line (on the C's side especially), I do not expect the T to look through bodies and make this call.
