Sam, there was a SanBar KTU that allowed a two-way radio (half duplex) circuit to be interfaced to a PU key on a 1A2 set. A converted signal key on the telset became the PTT of the radio. Or a G5 handset could be installed. Maybe that's what you were thinking of.
The 425 KTU (that succeeded the 225, with wire spring relays) superinposed GRD/GEN on a pair, under control of a SIG lead to allow an OPX off a dial ICM.
Bugging? legal and illegal? I worked in Harlem from 1970 to 1989. I saw every possible example.
It would take a book to tell all the stories.
