Collect call

A collect call is a type of telephone call that is made at a payphone, but is charged to the person receiving the call.

Doctor Rebos made a call on a payphone to the SDI and he left a message, but he was interrupted by the operator, who told him he has to pay five more cents. So because of this, his call was interrupted, and his message cut short, so Robin said if he would have made a collect call they would have learned a whole lot more.
