Explanation

Ad hoc conference restriction prevents a form of toll fraud called 'call transfer fraud' or 'conference toll fraud,' where an internal user bridges two external (off-net) PSTN calls together into a conference, leaving the company paying for both legs. By restricting ad hoc conferencing - or specifically blocking off-net-to-off-net conference legs - CUCM eliminates this attack vector. Option C ('Allow off-net to off-net transfers') actually enables toll fraud, not prevents it. Option D (route patterns) controls routing but does not by itself prevent fraud without proper Class of Service restrictions.
