Asterisk – Resolve callerid using online phone directories.

Here’s how to automatically resolve incoming callerids using a public online phone directory with a bit of PHP.

First you need a few packages installed.. php(4/5)-cli and php(4/5)-curl.. Copy the following code and save it as a file (‘resolvnum.agi’) in your agi-bin directory, most likely /usr/share/asterisk/agi-bin. Make sure it’s executable: chmod +rx resolvnum.agi

#!/usr/bin/php -q

// Do not wait more than 4 secs..

$stdin = fopen("php://stdin", "r");
$stdout = fopen("php://stdout", "w");

// Get all agi-variables from asterisk via stdin:
while (!feof($stdin)) {
        $temp = fgets($stdin);
        $temp = str_replace("n", "", $temp);
        $s = explode(":", $temp);
        $agivar[$s[0]] = trim($s[1]);

        if (($temp == "") || ($temp == "n"))

// Get callerid from agi-variables.
$callerid = $agivar['agi_callerid'];

if (!is_numeric($callerid)) exit(1);

// Set up curl:
$user_agent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";
$ch = @curl_init("".$callerid."&x=0&y=0/");

@curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
@curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
@curl_setopt($ch, CURLOPT_TIMEOUT,4);

// Fetch us some data...
$html = str_replace("r", "", @curl_exec($ch));

// Got nothing? Oh, bother...
if (!$html) exit(0);

// Replace Norwegian characters..
$html = str_replace(array(chr(230), chr(248), chr(229), chr(198), chr(216), chr(197)),
                 array("ae", "oe", "aa", "AE", "OE", "AA"), $html);

// Try to match some names..
preg_match_all("|<h4 class="forste_linje">n(.*)n</h4>|U", $html, $names, PREG_SET_ORDER);

// Yay, we found something, set calleridname.. leave number alone..
if (isset($names[0][1])) {
        fputs($stdout,"SET CALLERID "".$names[0][1]." (".$callerid.") <".$callerid.">"n");


Then add the agi to your incoming extensions in extensions.conf. Mine is set up like this:

exten => 85XXXXXX,1,AGI(nummeroppslag.agi)
exten => 85XXXXXX,2,Macro(dialer,101,SIP/101&SIP/102,101)
exten => 85XXXXXX,3,Hangup

It should now query and set the callerid-name (which will show up on your phone) if it finds something. Since I’m pretty sure that kvasir won’t like this (I take no responsibility for your usage), I would recommend implementing a cache if you have a lot of traffic. You can also easily adapt it to other phone directories by changing the search URL and regexp.
