Problem users without prior command structure knowledge actually have a higher probability of finding a valid DTMF command when pre access / site prefixing is not used as there are likely more sequences that do something somewhere.
Either control scheme should be supplemented with supervisory level commands that can lock down sites if / when a fly becomes problematic (and as Skipp said metro areas many times have lots of flies). Site prefixing (with supervisory lock down commands) is used by every medium to large network I know of. Having both control methods available allows the system management to choose whichever method they prefer. Not having the ability for site prefixing eliminates those controllers for applications where it is desired / implemented as part of the system structure. Ed Yoho WA6RQD
