Tapes sound good: ground controller is in the tower with the (tower), also reffered to as local Controller. Coordination to cross a runway requires ground control to coordinate with local. That is not always done on a recorded line. All towers are required to have procedures to alert both controllers when crossing runway. That ranges from, flight strips, lights, manuel promps as well as frequency warning when activated.
In most cases, ground thought they were cleared to cross however, someone screwed up.
What is needed is advanced electronic runway surveillance that communicated with pilot amd tower. There are some systems such as RWSL but these are not at all airports. Crossing runways is the greatest hazard at airports. Saw a SWA amd PA31 dang near prang each other out of the sky at DAL years ago.
