Hopefully this is self documented and a little less obtuse.
Then the context you can send calls to:-
[from-nanp-trunks-susceptible-to-being-on-the-fcc-list]
exten => _X.,1,Set(CALLERID(number)=${CALLERID(number):-10})
same => n,Set(VALUE=${DB(blacklist/${CALLERID(num)})})
same => n,Set(LEVEL=${CUT(VALUE,-,2)})
same => n,gotoif($["${LEVEL}" = ""]?from-pstn,${EXTEN},1)
same => n,Playback(custom/fccsorry)
same => n,SayDigits(${CALLERID(num)})
same => n,Playback(custom/fccisblacklisted)
same => n,Set(PASSCODE=${RAND(100,999)})
same => n,SayNumber(${level})
same => n,Playback(custom/fccruhuman)
same => n,SayDigits(${PASSCODE}
same => n,PlayBack(custom/fccafterbeep)
same => n,read(HUMAN,beep,3,,,5)
same => n,gotoif($["${HUMAN}" = "${PASSCODE}" ]?voicemail:hangup)
same => n(voicemail),PlayBack(custom/fccconfirmedcode)
same => n,Voicemail(3101,s) ; WHERE 3101 is the the voicemail box of your sentient adult in charge
same => n(hangup),hangup
You get to record the custom/fcc*prompts, maybe something like
fccsorry: . . . . . .We are sorry, but your callerID . . .
fccisblacklisted: is on the fcc blacklist of robocallers and spammers for a count of
fccruhuman: To prove you are a human please dial
fccafterbeep: After the beep.
fccconfirmcode: Thank you. Please leave a message after the beep, include your phone number,
who you are and what your call is about.
It covers the ongoing conversations at the other site that got fahrenheit 451'ed , first off it t confuses the machines, then it covers the FedEX guys to actually let you know they are regular, and you can whitelist them as soon as you get the email. You don't need Superfecta and it should cover the whitelist/blacklist contretemps as the traditionally the Asterisk blacklist just looks at the "value" this script filters on the existance of FCC in value,
Also note that the context
from-nanp-trunks-susceptible-to-being-on-the-fcc-list
falls through to from-pstn "very quickly" if not needed. Those quick enough will notice that DB(blacklist*) could easily be replace with DB(fccblacklist*) making this whole snippet completely transparent to FreePBX yet attentive at level 1 to the FCC list (Please watch the logs, the list is NOT realtime, as some have stated, it updates at about every 25 to 28 hours, but might be real-time sometime real-soon (maybe) so please adjust down your cron job appropriately perhaps is sufficient (yes this is a little grumpy for root to do it

Any peer comments would be much appreciated, especially if you have actual tried it
