At our TOC drivers must not use the GSMR, PA or cab-cab unless in an emergency. If the signaller calls you on the move, you bring your train to a stand at the first suitable location and call them back (or pick the handset up if they're still there).
As a matter of interest, did the same rule apply in pre-GSMR days, ie with NRN ? I ask because Control was required to make NRN Test Calls, in theory from every single Base Station at least once a month, to make sure the system was working and also so that every Controller was able to immediately make an Emergency Call if needed. I don't ever recall a Driver stopping their train in such circumstances !
