Otherwise, true is returned.[...]" Hello Nicolas, Before your quoted text there is this statement "Finds the longest prefix that matches the request URI user (or the number parameter) for the given user and domain name in the database." This means that you might have in the db a blacklist rule for the desired user for prefix 555123, that this will match the numbers 5551234 and 5551235. But you want to allow one of these numbers to be called by that user, you can specify that 5551234 is whitelisted. > Question: > > 1.) Is "not whitelisted" equal to "blacklisted"? Before your quoted text there is this statement "Finds the longest prefix that matches the request URI user (or the number parameter) for the given user and domain name in the database." This means that you might have in the db a blacklist rule for the desired user for prefix 555123, that this will match the numbers 5551234 and 5551235(and others of course). But you want to allow one of these numbers to be called by that user, you can specify that 5551234 is whitelisted. To answer your question no, if a R-URI is not whitelisted then it will be blacklisted only if there is a prefix that will match it(it the userblacklist table is empty no numbers are blacklisted) > 2.) Why is "false" returned if the blacklist_check is positive? This is the interface. The example in the documentation is like this: $avp(i:80) = $rU; # rewrite the R-URI if (!check_user_blacklist("$avp(i:80)", "$avp(i:82)")) sl_send_reply("403", "Forbidden"); exit; } > 3.) Is "true" even returned if there's no match? The check_use_blacklist will return true if no blacklisted prefix match is found, or a longer whitelisted prefix is found. For example if you have 123 blacklisted and 1234 whitelisted, 12345 will be whitelisted but 1233 will be blacklisted. > I'd have expected the following: > > if (user_is_blacklisted) > then return TRUE; > else return FALSE; > > > Can you please clarify the behavior?
