Asterisk: The Future of Telephony, 2nd Edition

Name

LookupBlacklist() — Performs a lookup of a Caller ID name/number from the blacklist database

Synopsis

LookupBlacklist([options])

Note

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()
