LookupBlacklist() — Performs a lookup of a Caller ID name/number from the blacklist database
This application has been deprecated in favor of
GotoIf(${BLACKLIST()}?context|extension|priority)
Looks up the Caller ID number on the active channel in the
Asterisk database (family blacklist).
If the Caller ID number is found in the blacklist, Asterisk sets the
LOOKUPBLSTATUS channel variable to
FOUND. Otherwise, the variable is set
to NOTFOUND.
If the j option is used in the
options parameter, and the number is found,
and if there exists a priority n+101
(where n is the priority of the
current instance), the channel will be set up to continue at that
priority level.
To add to the blacklist from the Asterisk CLI, type database put blacklist name/ number
; send blacklisted numbers to an endless loop
; otherwise, dial the number defined by the variable ${JOHN}
exten => 123,1,Answer()
exten => s,2,LookupBlacklist()
; if the Caller ID number is found in the blacklist, jump to the "goaway" label
exten => 123,n,GotoIf($["${LOOKUPBLSTATUS}" = "FOUND"]?goaway)
; otherwise, go ahead and call John
exten => 123,n,Dial(${JOHN})
exten => 123,n(goaway),Busy(5)
exten => 123,n,Hangup()
