But you could implement your own pattern matching logic in your dialplan
and block anything you like, including a range of numbers. You could for
example strip the callerid number down to just the area code, check that
agains a blocked list. Or you could get creative with regular
expressions. Take this rather nasty segment from my own dialplan....
; Check against blacklist
same => n,GotoIf(${DB_EXISTS(blacklist/${CALLERID(num)})}?onblacklist)
; Not on blacklist, check Caller ID number for anonymous conditions...
; If all zeros (with or without international dialing + sign) then caller
is anonymous.
same => n,GotoIf($[${REGEX("^[+]?0+$" ${CALLERID(num)})} = 1]?unknown)
; If Caller ID is not a number at least 4 digits long (with or without +
sign)
; then caller is assumed to be anonymous. Alphabetic Caller ID "numbers"
; will therefore be considered anonymous. Common numbers for anonymous
callers
; are: "asterisk, unknown, anonymous, private, unavailable" which may be
upper, lower
; or mixed case. The regular expression catches everything non-numeric.
; If you want to permit a specific non-numeric Caller ID "number" add it
to whitelist.
same => n,GotoIf($[${REGEX("^[+]?[0-9]{4\,}$" ${CALLERID(num)})} !=
1]?unknown)
; Caller ID looks good.
